Boeing Aims To Bring Flying Cars To Asia By 2030

Par : msmash
18 avril 2024 à 19:22
U.S. aircraft manufacturer Boeing plans to enter the flying car business in Asia by 2030, looking to tap demand for the fast travel the vehicles could provide in the region's traffic-choked cities. Nikkei: Boeing Chief Technology Officer Todd Citron revealed the plans in an interview with Nikkei. The company is developing electric vertical take-off and landing (eVTOL) craft at subsidiary Wisk Aero. The aircraft will adopt autonomous technology, rare among eVTOL craft. The plan is to first obtain certification in the U.S. before expanding into Asia. Details of the Asia business will be finalized in the future, including whether Boeing will sell the aircraft to companies aiming to provide eVTOL transportation services or operate the services itself. Boeing is currently considering which country in Asia to enter first, including Japan. In Japan, domestic startup SkyDrive and Germany's Volocopter are scheduled to operate air taxi services at the 2025 Osaka World Expo. Boeing opened a research and development base in Nagoya on Thursday. It first established R&D operations in Japan in 2022 but had been renting space from other companies until now.

Emissions Dropped 1.8% Every Year in California's Bay Area. Researchers Credit EVs

Par : EditorDavid
15 avril 2024 à 11:34
An anonymous reader shared this report from the Los Angeles Times: A network of air monitors installed in Northern California has provided scientists with some of the first measurable evidence quantifying how much electric vehicles are shrinking the carbon footprint of a large urban area. Researchers from UC Berkeley set up dozens of sensors across the Bay Area to monitor planet-warming carbon dioxide, the super-abundant greenhouse gas produced when fossil fuels are burned. Between 2018 and 2022, the region's carbon emissions fell by 1.8% each year, which the Berkeley researchers concluded was almost exclusively owed to drivers switching to electric vehicles, according to a study published in the journal Environmental Science & Technology. In that time, Californians purchased about 719,500 zero-emission or plug-in hybrid vehicles, more than triple the amount compared to the previous five years, according to the California Department of Energy. The Bay Area also had a higher rate of electric vehicle adoption than the state as a whole. While the findings confirm the state's transition to zero-emission vehicles is substantially lowering carbon emissions, it also reveals these reductions are still not on pace to meet the state's ambitious climate goals. Emissions need to be cut by around 3.7% annually, or nearly twice the rate observed by the monitors, according to Ronald Cohen, UC Berkeley professor of chemistry. Although cars and trucks are the state's largest source of carbon emissions, it underscores the need to deploy zero-emission technology inside homes and for the power grid. "I think what we see right now is evidence of strong success in the transportation sector," Cohen said. "We're going to need equally strong success in home and commercial heating, and in the [industrial] sources. We don't yet see significant movement in those, but policy pushing on those is not as far ahead as policy on electric vehicles." Although cities only cover roughly 3% of global surface area, they produce about 70% of carbon emissions.

Two Boeing Whistleblowers Allege Disregarded Worker Concerns, Pressure For Speed

"Federal regulators are investigating a whistleblower's claims about flaws in the assembly of Boeing's 787 Dreamliner," NPR reported this week: Longtime Boeing engineer Sam Salehpour went public Tuesday with claims that he observed problems with how parts of the plane's fuselage were fastened together. Salehpour warns that production "shortcuts" could significantly shorten the lifespan of the plane, eventually causing the fuselage to fall apart in mid-flight. "It can cause a catastrophic failure," Salehpour said Tuesday during a press briefing to discuss his claims. A spokesman for the FAA confirmed that the agency is investigating those allegations, which were first reported by the New York Times, but declined to comment further on them. Boeing immediately pushed back. "These claims about the structural integrity of the 787 are inaccurate and do not represent the comprehensive work Boeing has done to ensure the quality and long-term safety of the aircraft," Boeing spokeswoman Jessica Kowal said in a statement. "We are fully confident in the 787 Dreamliner." Salehpour and his lawyers argue that Boeing has never adequately addressed production flaws discovered in 2021 (which included unacceptable gaps between the fuselage panels), according to the article. "Instead, he says the company took 'shortcuts' by applying greater force to fit segments of the fuselage together." "Boeing hid the problem by pushing the pieces together with force to make it appear like that the gap didn't exist," Salehpour told reporters at Tuesday's press briefing. Salehpour says he repeatedly raised these concerns with management, but instead of addressing them, they transferred him to work on a different plane, the 777, where he alleges he saw similar problems. "I literally saw people jumping on the pieces of the airplane to get them to align," he said. "That's not how you build a plane." In a follow-up piece, NPR reports that former Boeing mechanic Davin Fischer "says he spoke up — and paid a steep price for it." He says Boeing's leaders were constantly pushing to speed up production. "Hey, we need to go faster, faster, faster," Fischer said. "They cared more about shareholders and investors than they did planes, their employees, anything." When Fischer finally pushed back, he says he was demoted in retaliation, and then fired from the company in 2019. Fischer says many of his friends who still work at Boeing are afraid to speak out. "People there are scared, a hundred percent," he said. "Because they don't want to get fired." NPR also cites the example of longtime quality manager John Barnett, who said in a 2019 interview with Ralph Nader that his managers at Boeing retaliated against him by docking his pay and creating a hostile environment.

Should the US Ban Chinese EVs?

Par : BeauHD
13 avril 2024 à 13:00
An anonymous reader quotes a report from Ars Technica: Influential US Senator Sherrod Brown (D-Ohio) has called on U.S. President Joe Biden to ban electric vehicles from Chinese brands. Brown calls Chinese EVs "an existential threat" to the U.S. automotive industry and says that allowing imports of cheap EVs from Chinese brands "is inconsistent with a pro-worker industrial policy." Brown's letter to the president (PDF) is the most recent to sound alarms about the threat of heavily subsidized Chinese EVs moving into established markets. Brands like BYD and MG have been on sale in the European Union for some years now, and last October, the EU launched an anti-subsidy investigation into whether the Chinese government is giving Chinese brands an unfair advantage. The EU probe won't wrap until November, but another report published this week found that government subsidies for green technology companies are prevalent in China. BYD, which now sells more EVs than Tesla, has benefited from almost $4 billion (3.7 billion euro) in direct help from the Chinese government in 2022, according to a study by the Kiel Institute. Last month, the EU even started paying extra attention to imports of Chinese EVs, issuing a threat of retroactive tariffs that could start being imposed this summer. Chinese EV imports to the EU have increased by 14 percent since the start of its investigation, but they have yet to really begin in the U.S., where there are a few barriers in their way. Chinese batteries make an EV ineligible for the IRS's clean vehicle tax credit, for one thing. And Chinese-made vehicles (like the Lincoln Nautilus, Buick Envision, and Polestar 2) are already subject to a 27.5 percent import tax. But Chinese EVs are on sale in Mexico already, and that has American automakers worried. Last year, Ford CEO Jim Farley said he saw Chinese automakers "as the main competitors, not GM or Toyota." And in January, Tesla CEO Elon Musk said he believed that "if there are no trade barriers established, they will pretty much demolish most other car companies in the world." [...] It's not just the potential damage to the U.S. auto industry that has prompted this letter. Brown wrote that he is concerned about the risk of China having access to data collected by connected cars, "whether it be information about traffic patterns, critical infrastructure, or the lives of Americans," pointing out that "China does not allow American-made electric vehicles near their official buildings." At the end of February, the Commerce Department also warned of the security risk from Chinese-connected cars and revealed it has launched an investigation into the matter. "When the goal is to dominate a sector, tariffs are insufficient to stop their attack on American manufacturing," Brown wrote. "Instead, the Administration should act now to ban Chinese EVs before they destroy the potential for the U.S. EV market. For this reason, no solution should be left off the table, including the use of Section 421 (China Safeguard) of the Trade Act of 1974, or some other authority."

Waymo Launches Paid Robotaxi Service In Los Angeles

Par : BeauHD
10 avril 2024 à 13:40
Beginning today, Waymo said it would start offering paid robotaxi rides in Los Angeles. It's been offering free "on tour" rides since it announced plans for the service in January, and last month it received regulatory approval for the expansion to a paid service. NBC News reports: Waymo said Tuesday that more than 50,000 people were on its waitlist to use the service. The company did not say how many users it would allow to fully use the app starting Wednesday. Last month, the company said it was starting with a Los Angeles fleet of fewer than 50 cars covering a 63-square-mile area from Santa Monica to downtown L.A. Los Angeles County has a population of 9.7 million people. The service works similarly to other ride-hailing smartphone apps such as Flywheel, Lyft and Uber, except that Waymo's vehicles have no human drivers present. Riders follow instructions on the app and through the vehicle's sound system, though Waymo workers can assist remotely. [F]or now, Waymo's only competition is traditional, human-driven car services. Waymo's expansion to Los Angeles will bring autonomous for-profit taxis to the nation's second-largest city -- and to a city long synonymous with car travel. Waymo already operates commercial robotaxi services in San Francisco and Phoenix. The Los Angeles Department of Transportation said the Waymo expansion was happening too soon, without enough local oversight of autonomous vehicle operations, but in an order last month state officials said that those concerns were unfounded.

Cruise Robotaxis Are Back in Phoenix - But People Are Driving Them

Cruise is redeploying robotaxis in Phoenix after nearly five months of paused operations, the company said in a blog post. The catch? The cars will be in so-called "manual mode," so they won't be driving themselves. From a report: Cruise will resume manual driving of its autonomous vehicles to create maps and gather road information in certain cities, starting with Phoenix, the company said Tuesday. The General Motors subsidiary already had a presence in Phoenix before it pulled its entire U.S.-based fleet last year following an incident in San Francisco that left a pedestrian stuck under and dragged by a Cruise robotaxi. Prior to that incident, Cruise had been announcing launches in new cities -- including Dallas, Houston and Miami -- at a startling pace. Critics accused the company of expanding too fast and cutting corners on safety.

Report: Boeing 'Put Wall Street First, Safety Second', Creating 'Yearslong Decline of Safety Standards'

Par : EditorDavid
8 avril 2024 à 11:34
The Seattle Times has a Pulitzer Prize-winning aerospace journalist named Dominic Gates. Sunday he published an expose on "a yearslong decline of safety standards" at Boeing. After a 1997 merger, its new executive leaders "treated experienced engineers and machinists as expendable, ignoring the potential damage to Boeing's essential mission of designing and building high-quality airplanes...." The arc of Boeing's fall can be traced back a quarter century, to when its leaders elevated the interests of shareholders above all others, said Richard Aboulafia, industry analyst with AeroDynamic Advisory. "Crush the workers. Share price. Share price. Share price. Financial moves and metrics come first," was Boeing's philosophy, he said. It was, he said, "a ruthless effort to cut costs without any realization of what it could do to capabilities...." Its leaders outsourced work, sold off whole divisions and discarded key capabilities such as developing avionics, machining parts and building fuselages. On the 787, they even outsourced the jet's wings to Japan. They moved work away from Boeing's highly skilled, unionized base in the Puget Sound region. They weakened unions and extorted state government with repeated threats to build future airplanes elsewhere. They squeezed suppliers by demanding price cuts every year that in turn forced the suppliers into ruinous cost-cutting and left them vulnerable to collapse during shocks like the COVID-19 pandemic.... Belatedly, Boeing's current leaders, overwhelmed by criticism, mockery and outrage since January, have finally admitted publicly that some key strategies they pursued for decades were flawed. "Boeing, more than 20 years ago, probably got a little too far ahead of itself on the topic of outsourcing," Chief Financial Officer Brian West said last month. And in January, on CNBC, Boeing Chief Executive Dave Calhoun conceded: "Did it go too far? Yeah, probably did." Both were speaking about major supplier Spirit AeroSystems of Wichita, Kan., part of Boeing until it was sold off two decades ago, part of a broad divestment of assets to please Wall Street and boost the stock. Following a litany of quality lapses in Wichita, Boeing is now admitting a mistake and trying to buy Spirit back — "for safety and for quality," said West. Another mistake belatedly recognized: With annual bonuses for Boeing's factory managers based largely on meeting cost and schedule targets, it was long a cardinal sin to stop the assembly line. That meant unfinished jobs piled up on aircraft as they moved forward down the line, what Boeing calls "traveled work." Done out of sequence, this work is more difficult and takes much longer. If too much traveled work piles up, it creates chaos. That's what happened in Renton on the 737 assembly line. "For years, we prioritized the movement of the airplane through the factory over getting it done right, and that's got to change," West said. "Once you reduce traveled work, your quality gets better...." Speaking of how Spirit might be fixed, West said: "It's really about focus and running it, not as a business, as a factory. Run it as a factory and stay focused on safety and quality and stability." Phil Chandler, a highly skilled Boeing machinist for more than 42 years (retiring in 2020), saw a "dictatorial" approach on the factory floor, according to the article. "Whereas in the past, first-level and even second-level managers in the factory had come up through the ranks as mechanics and had deep knowledge of the work, after [Boeing president Harry] Stonecipher came in those jobs shifted to white-collar people with degrees, often with MBAs." And a former Boeing physicist also complains about the "shoot-the-messenger" management approach when developing their 787, according to the article: "Engineers who raised technical doubts were told: 'Follow the plan. If you can't do your job, I'll fire you and get someone who can.'"

Boeing Engine Cover Rips Apart During Takeoff This Morning

"Scary moments for passengers on a Southwest flight from Denver to Houston," tweets an ABC News transportation reporter, "when the engine cover ripped off during flight, forcing the plane to return to Denver Sunday morning." "Think that big circular metal panel surrounding the engine," writes QZ — adding that after it ripped off, the engine cowling "struck the 737-800's wing flap." It happened during takeoff, so the plane was towed back to the gate after returning to the airport. All passengers and crew were safe, and passengers boarded a replacement plane for their flight to Houston: Southwest was already having a rough few weeks before this event occurred. Last Thursday, an engine on one of its Boeing 737-800 planes caught fire before taking off from an airport in Texas, and before that, two FAA-scrutinized Southwest flights were disrupted by turbulence [One last month in New York City and the other in Florida on Wednesday. "Two hours later, an All Nippon Airways Boeing 787 reported an oil leak on arrival at Naha Airport, Japan," adds Newsweek.]. "We apologize for the inconvenience of their delay," Boeing said in a statement, adding that they "place our highest priority on ultimate Safety for our Customers and Employees. "Our Maintenance teams are reviewing the aircraft."

Elon Musk Says Tesla Will Unveil Its Robotaxi on August 8

The San Francisco Chronicle reports that Tesla "is poised to roll out its version of a robotaxi later this year, according to CEO Elon Musk." ("Musk made the announcement on social media saying 'Tesla Robotaxi unveil on 8/8.' His cryptic post contained no other details about the forthcoming line of autonomous vehicles.") Electrek thinks they know what it'll look like. "Through Walter Issacson's approved biography of Musk, we learned that Tesla Robotaxi will be 'Cybertruck-like'." 8/8 (of the year 2024) would be a Thursday — although CNBC adds one additional clarification: At Tesla, "unveil" dates do not predict a near-future date for a commercial release of a new product. For example, Tesla unveiled its fully electric heavy-duty truck, the Semi, in 2017 and did not begin deliveries until December 2022. It still produces and sells very few Semis to this day. "Tesla shares rose over 3% in extended trading after Musk's tweet."

Will EVs Kill the Stick Shift Car?

Par : EditorDavid
31 mars 2024 à 11:34
A CNN opinion piece looks at "the moaning about manual transmission's demise," noting that "it's not just Europeans (literally) clinging on. In the U.S., there's apparently a young (also predominantly male) demographic that is embracing manual driving — championing it as retro, much like Gen Z's affinity to typewriters and vintage cameras. "They feel there's something authentic about it: a connection between driver and vehicle that automatization cuts out." But CNN's writer argues the case against stick shifts... [Automatic vehicles] chalk up better mileage and drive faster than their stick-shift counterparts. The explanation: automatics select the right gear for the vehicle, usually the highest gear possible. The average manual driver is not always so proficient. In getting the gear right, automatics consume less fuel, save money and emit fewer emissions. These are among the reasons why it's ever harder to buy a new manual-transmission model of any kind in many countries. In the US, less than 1% of new models have stick shifts (compared to 35% in 1980), according to the Environmental Protection Agency. It's really only sports cars, off-road truck SUVs and a handful of small pickups that still have clutches.... While all gasoline-run cars and trucks are climate killers with stick shifts being the slightly worse of two evils, combustion-engine automatics themselves are on their way out. They are tooling along the highway side-by-side with their stick-and-clutch counterparts toward the junkyard of history. Electric vehicles have gear systems, too: a single speed transmission that transmits energy from the motor to the wheels. But because only one gear exists, there is no switching of gears, neither automatically nor manually... Road transportation accounts for 15% of the world's greenhouse gas emissions, according to Our World Data, as well as being a huge contributor to the air pollution that claims around nine million deaths a year from respiratory and lung diseases. Transportation noise, though less deadly, also contributes to stress and sleep disorders. Thankfully, there's a convenient way to circumvent these blights: electric vehicles... But for those aficionados who really can't go without a clutch and gear shifter, Toyota is planning a realistic-feeling fake manual transmission for some EV models. It serves no purpose whatsoever — save to comfort bruised egos.

New Pollution Rules Aim To Lift Sales of Electric Trucks

Par : BeauHD
30 mars 2024 à 03:30
An anonymous reader quotes a report from the New York Times: The Biden administration on Friday announced a regulation designed to turbocharge sales of electric or other zero-emission heavy vehicles, from school buses to cement mixers, as part of its multifront attack on global warming. The Environmental Protection Agency projects the new rule could mean that 25 percent of new long-haul trucks, the heaviest on the road, and 40 percent of medium-size trucks, like box trucks and landscaping vehicles, could be nonpolluting by 2032. Today, fewer than 2 percent of new heavy trucks sold in the United States fit that bill. The regulation would apply to more than 100 types of vehicles including tractor-trailers, ambulances, R.V.s, garbage trucks and moving vans. The rule does not mandate the sales of electric trucks or any other type of zero or low-emission truck. Rather, it increasingly limits the amount of pollution allowed from trucks across a manufacturer's product line over time, starting in model year 2027. It would be up to the manufacturer to decide how to comply. Options could include using technologies like hybrids or hydrogen fuel cells or sharply increasing the fuel efficiency of the conventional trucks. The truck regulation follows another rule made final last week that is designed to ensure that the majority of new passenger cars and light trucks sold in the United States are all-electric or hybrids by 2032, up from just 7.6 percent last year. Together, the car and truck rules are intended to slash carbon dioxide pollution from transportation, the nation's largest source of the fossil fuel emissions that are driving climate change and that helped to make 2023 the hottest year in recorded history. Electric vehicles are central to President Biden's strategy to confront global warming, which calls for cutting the nation's emissions in half by the end of this decade.

New York City Welcomes Robotaxis - But Only With Safety Drivers

Par : msmash
28 mars 2024 à 18:40
An anonymous reader shares a report: New York City announced a new permitting system for companies interested in testing autonomous vehicles on its roads, including a requirement that a human safety driver sit behind the steering wheel at all times. As cities like San Francisco continue to grapple with the problems posed by fully driverless for-hire vehicles, New York City is trying to get ahead of the problem by outlining what it calls "a rigorous permitting program" that it claims will ensure applicants are "ready to test their technology in the country's most challenging urban environment safely and proficiently." "This technology is coming whether we like it or not," Mayor Eric Adams said in a statement to The Verge, "so we're going to make sure that we get it right." The requirements would exclude companies without previous autonomous vehicle testing experience in other cities. Applicants would need to submit information from previous tests, including details on any crashes that occurred and how often safety drivers have to take control of the vehicle (also known in California as "disengagements"). And in what is sure to be the most controversial provision, fully driverless vehicles won't be permitted to test on the city's public roads; only vehicles with safety drivers will be allowed.

Air Industry Trends Safer, But 'Flukish' Second Crash Led Boeing to Mishandled Media Storm, WSJ Argues

Par : EditorDavid
23 mars 2024 à 22:34
There's actually "a global trend toward increased air safety," notes a Wall Street Journal columnist. And even in the case of the two fatal Boeing crashes five years ago, he stresses that they were "were two different crashes," with the second happening only "after Boeing and the FAA issued emergency directives instructing pilots how to compensate for Boeing's poorly designed flight control software. "The story should have ended after the first crash except the second set of pilots behaved in unexpected, unpredictable ways, flying a flyable Ethiopian Airlines jet into the ground." Boeing is guilty of designing a fallible system and placing an undue burden on pilots. The evidence strongly suggests, however, that the Ethiopian crew was never required to master the simple remedy despite the global furor occasioned by the first crash. To boot, they committed an additional error by overspeeding the aircraft in defiance of aural, visual and stick-shaker warnings against doing so. It got almost no coverage, but on the same day the Ethiopian government issued its final findings on the accident in late 2022, the U.S. National Transportation Safety Board, in what it called an "unusual step," issued its own "comment" rebuking the Ethiopian report for "inaccurate" statements, for ignoring the crew's role, for ignoring how readily the accident should have been avoided. So the Wall Street Journal columnist challenges whether profit incentives played any role in Boeing's troubles: In reality, the global industry was reorganized largely along competitive profit-and-loss lines after the 1970s, and yet this coincided with enormous increases in safety, notwithstanding the sausage factory elements occasionally on display (witness the little-reported parking of hundreds of Airbus planes over a faulty new engine). The point here isn't blame but to note that 100,000 repetitions likely wouldn't reproduce the flukish second MAX crash and everything that followed from it. Rather than surfacing Boeing's deeply hidden problems, it seems the second crash gave birth to them. The subsequent 20-month grounding and production shutdown, combined with Covid, cost Boeing thousands of skilled workers. The pressure of its duopoly competition with Airbus plus customers clamoring for their backordered planes made management unwisely desperate to restart production. January's nonfatal door-plug blowout of an Alaska Airlines 737 appears to have been a one-off when Boeing workers failed to reinstall the plug properly after removing it to fix faulty fuselage rivets. Not a one-off, apparently, are faulty rivets as Boeing has strained to hire new staff and resume production of half-finished planes. Boeing will sort out its troubles eventually by applying the oldest of manufacturing insights: Training, repetition, standardization and careful documentation are the way to error-free complex manufacturing. As he sees it, "The second MAX crash caught Boeing up in a disorienting global media and political storm that it didn't know how to handle and, indeed, has handled fairly badly."

Truck-To-Truck Worm Could Infect Entire US Fleet

Par : BeauHD
23 mars 2024 à 10:00
Jessica Lyons reports via The Register: Vulnerabilities in common Electronic Logging Devices (ELDs) required in US commercial trucks could be present in over 14 million medium- and heavy-duty rigs, according to boffins at Colorado State University. In a paper presented at the 2024 Network and Distributed System Security Symposium, associate professor Jeremy Daily and systems engineering graduate students Jake Jepson and Rik Chatterjee demonstrated how ELDs can be accessed over Bluetooth or Wi-Fi connections to take control of a truck, manipulate data, and spread malware between vehicles. "These findings highlight an urgent need to improve the security posture in ELD systems," the trio wrote [PDF]. The authors did not specify brands or models of ELDs that are vulnerable to the security flaws they highlight in the paper. But they do note there's not too much diversity of products on the market. While there are some 880 devices registered, "only a few tens of distinct ELD models" have hit the road in commercial trucks. A federal mandate requires most heavy-duty trucks to be equipped with ELDs, which track driving hours. These systems also log data on engine operation, vehicle movement and distances driven -- but they aren't required to have tested safety controls built in. And according to the researchers, they can be wirelessly manipulated by another car on the road to, for example, force a truck to pull over. The academics pointed out three vulnerabilities in ELDs. They used bench level testing systems for the demo, as well as additional testing on a moving 2014 Kenworth T270 Class 6 research truck equipped with a vulnerable ELD. [...] For one of the attacks, the boffins showed how anyone within wireless range could use the device's Wi-Fi and Bluetooth radios to send an arbitrary CAN message that could disrupt of some of the vehicle's systems. A second attack scenario, which also required the attacker to be within wireless range, involved connecting to the device and uploading malicious firmware to manipulate data and vehicle operations. Finally, in what the authors described as the "most concerning" scenario, they uploaded a truck-to-truck worm. The worm uses the compromised device's Wi-Fi capabilities to search for other vulnerable ELDs nearby. After finding the right ELDs, the worm uses default credentials to establish a connection, drops its malicious code on the next ELD, overwrites existing firmware, and then starts the process over again, scanning for additional devices. "Such an attack could lead to widespread disruptions in commercial fleets, with severe safety and operational implications," the researchers warned.

Boom's XB-1 Supersonic Demonstrator Makes First Flight

Par : BeauHD
22 mars 2024 à 22:40
Boom Supersonic's first aircraft, the XB-1, completed its first flight today and met "all of its test objectives." From a report: This initial test only saw the aircraft 7,120 feet above sea level and fly at a top speed of 238 knots (274 mph) -- far from Mach 1, the speed of sound. The first flight of XB-1 took place at the Mojave Air & Space Port in California, in the same airspace where the X-1 broke the sound barrier, the X-15 conducted test flights for altitude and speed records, and the SR-71 Blackbird was also tested. According to Boom, the XB-1 will be testing, among other things: Augmented reality vision system: Two nose-mounted cameras, digitally augmented with attitude and flight path indications, feed a high-resolution pilot display enabling excellent runway visibility. This system allows for improved aerodynamic efficiency without the weight and complexity of a movable nose. Digitally-optimized aerodynamics: Engineers used computational fluid dynamics simulations to explore thousands of designs for XB-1. The result is an optimized design that combines safe and stable operation at takeoff and landing with efficiency at supersonic speeds. Carbon fiber composites: XB-1 is almost entirely made from carbon fiber composite materials, enabling it to realize a sophisticated aerodynamic design in a strong, lightweight structure. Supersonic intakes: XB-1's engine intakes slow supersonic air to subsonic speeds, efficiently converting kinetic energy into pressure energy and allowing conventional jet engines to power XB-1 from takeoff through supersonic flight. Another thing being tested by XB-1 is the construction of a safety culture. With XB-1 now a flying test vehicle, there are many flights ahead before we get to Overture One's first flight, much less dramatically expanding access to supersonic flight. This work will require much engineering and a resilient safety culture. But the first flight of the first step was carried out by Boom Supersonic today, March 22, 2024.

EPA Sets Strict New Limits On Tailpipe Emissions That Could Boost EV Sector

Par : BeauHD

sinij shares a report from the New York Post: The Biden administration finalized its crackdown on gas cars Wednesday, with the Environmental Protection Agency announcing drastic climate regulations meant to ensure more than two-thirds of passenger cars and light trucks sold by 2032 are electric or hybrid vehicles. The EPA rule imposes strict limits on tailpipe pollution, limits the agency says can be met if 56% of new vehicles sold in the US are electric by eight years from now, along with 13% that are plug-in hybrids or other partially electric cars. That would be a huge increase over current EV sales, which rose to 7.6% of new vehicle sales last year, up from 5.8% in 2022. [...] The new rule slows implementation of stricter pollution standards from 2027 through 2029, before ramping up to near the level the EPA preferred by 2032. "Personal car ownership is about to get A LOT more expensive as it will have to carry the costs of deep discounts to entice EV sales," adds Slashdot reader sinij.

Was Nosediving Boeing Plane Caused By a Flight Attendant Hitting a Motorized Seat Switch?

Par : EditorDavid
18 mars 2024 à 11:34
Last week 50 people were injured when a Boeing 787-9 Dreamliner experienced a sudden mid-air drop — raising concerns about the possibility of a new safety issue. But the Wall Street Journal offers a follow-up report. "A flight attendant hit a switch on the pilot's seat while serving a meal, leading a motorized feature to push the pilot into the controls and push down the plane's nose, according to U.S. industry officials briefed on preliminary evidence from an investigation." The switch, on the back of the chair, is usually covered and isn't supposed to be used when a pilot is in the seat. Boeing issued a memo late Thursday to operators of 787 jets recommending that they inspect the cockpit chairs for loose covers on the switches and instructing them how to turn off power to the pilot seat motor if needed. Boeing said it is considering updates to flight crew manuals. "Closing the spring-loaded seat back switch guard onto a loose/detached rocker switch cap can potentially jam the rocker switch, resulting in unintended seat movement," according to the memo, which was viewed by The Wall Street Journal. The memo says this was a known issue and that Boeing had issued a related service notice in 2017.... American Airlines issued a notice to 787 captains advising them of the potential hazard. It asked them to instruct the crew not to use the switch while the chair is occupied and said that its maintenance teams would check that the switches are properly secured. Ipeco, the cockpit seat supplier, didn't respond to the Journal's request for a comment. But in a new CNN video, a pilot demonstrates the location of the button — and speculates that a seat pushing a pilot forward could abruptly override the plane's auto-pilot system. "It would be good news for Boeing if it is cleared of any fault in the Latam flight," adds another CNN report. "The company is facing multiple investigations by both the Federal Aviation Administration and the National Transportation Safety Board..." The Journal's article includes footage from inside the plane just moments after the incident and notes that some passengers had been "pinned to the ceiling as the airplane suddenly descended."

Boeing Whistleblower Found Dead in Apparent Suicide

A Boeing quality manager for more than 30 years "learned of and exposed very serious safety problems with the Boeing 787 Dreamliner," according to his lawyers, "and was retaliated against and subjected to a hostile work environment." After retiring in 2017 he'd filed a whistleblower retaliation case, and "was in the middle of giving deposition testimony... when he died, his lawyers, Robert Turkewitz and Brian Knowles, told NPR." "He was in very good spirits and really looking forward to putting this phase of his life behind him and moving on," the South Carolina-based attorneys said in a joint statement. "We didn't see any indication he would take his own life. No one can believe it." Police said officers were sent to the hotel to conduct a welfare check after people were unable to contact Barnett, who had traveled to Charleston to testify in his lawsuit against Boeing. "Upon their arrival, officers discovered a male inside a vehicle suffering from a gunshot wound to the head," police said in a statement sent to NPR. "He was pronounced deceased at the scene...." Barnett, who spent decades working for Boeing at its plants in Everett, Washington, and North Charleston, South Carolina, had repeatedly alleged that Boeing's manufacturing practices had declined — and that rather than improve them, he added, managers had pressured workers not to document potential defects and problems. "We are saddened by Mr. Barnett's passing, and our thoughts are with his family and friends," Boeing said in a statement sent to NPR.... Barnett filed a whistleblower complaint against Boeing in early 2017; his case against the company was heading toward a trial this June, his family said. "He was looking forward to having his day in court and hoped that it would force Boeing to change its culture," the family said in a statement shared with NPR by his brother, Rodney Barnett. The family says Barnett's health declined because of the stresses of taking a stand against his longtime employer. "He was suffering from PTSD and anxiety attacks as a result of being subjected to the hostile work environment at Boeing," they said, "which we believe led to his death." "Two of his attorneys called on police to fully investigate how he had died," reports the BBC. And for what it's worth, the New York Post says Barnett "made a grim prediction that he could potentially end up dead after raising safety concerns about the jetliner giant, allegedly telling a family friend: 'If anything happens, it's not suicide.'" UPDATE: Fortune just published an article called "The last days of the Boeing whistleblower." Thanks to Slashdot readers wgoodman and sinij for sharing the article.

US Investigates Fatal Crash of Ford EV With Partially Automated Driving System

America's National Transportation Safety Board "is investigating a fatal crash in San Antonio, Texas, involving a Ford electric vehicle that may have been using a partially automated driving system," reports the Associated Press: The NTSB said that preliminary information shows a Ford Mustang Mach-E SUV equipped with the company's partially automated driving system collided with the rear of a Honda CR-V that was stopped in one of the highway lanes. Television station KSAT reported that the Mach-E driver told police the Honda was stopped in the middle lane with no lights on before the crash around 9:50 p.m. The 56-year-old driver of the CR-V was killed. "NTSB is investigating this fatal crash due to its continued interest in advanced driver assistance systems and how vehicle operators interact with these technologies," the agency statement said. Ford's Blue Cruise system allows drivers to take their hands off the steering wheel while it handles steering, braking and acceleration on highways. The company says the system isn't fully autonomous and it monitors drivers to make sure they pay attention to the road. It operates on 97% of controlled access highways in the U.S. and Canada, Ford says.
