Has a 787 ever broken the sound barrier?

Has a 787 ever broken the sound barrier? “Fair winds and following seas” ? a Virgin Atlantic's Boeing 787-9 Dreamliner reached a thrilling speed of 801 mph while flying over the United States. While this ground speed seemingly leaves behind the speed of sound (767 mph), the jetliner did not, in fact, magically turn supersonic.

Why is Boeing 787 a failure?

As Boeing examined its 787 production, certain defects came into focus: improperly sized shims that fill tiny gaps between sections of the airplane body, known as the fuselage, and variations on skin flatness in certain sections of the interior of the fuselage.

Why did Boeing stop delivering 787?

The latest announcement brings back memories of the delivery drought that affected Boeing's 787s not too long ago. Deliveries of the Boeing 787 were stopped by the FAA in May 2021 after production flaws surfaced and concerns over Boeing's inspection methods.

Is Boeing 787 loud?

The 787 is on average up to 7 dB quieter on departure than the 767, and up to 8 dB quieter than the A330 aircraft. The results also confirm that the 787 is up to 3 dB quieter on arrival than the aircraft types it is intended to replace.

Why is the 787 so special?

Ecologically, and compared to previous generation wide-body aircraft, the Dreamliner has avoided more than 85 billion pounds of carbon emissions, achieved 20-25% greater fuel efficiency, realized 20-45% more cargo revenue capacity, and produced a 60% smaller airport noise footprint.

Has a Boeing Dreamliner ever crashed?

A report in 2021 revealed that Boeing Dreamliners are among the world's safest planes in terms of accidents. There have been no fatalities or events involving extensive damage during more than a decade of flights using the model.

Has an a380 ever broken the sound barrier?

However, upon the completion of the test, the aircraft entered a shallow dive and started picking up speed, before breaking the sound barrier at approximately 10,000 meters (33,000 feet).

Can a Boeing 747 break the sound barrier?

Aircraft are put through extreme testing during their certification, but such limits are never intended to be actually faced. The 747 -100, for instance, was tested up to Mach 0.99, almost breaking the sound barrier. Other 747s, such as Air Force One, have approached the sound barrier but never crossed it.

Why is supersonic flight illegal?

Fifty years ago, the federal government banned all civilian supersonic flights over land. The rule prohibits non-military aircraft from flying faster than sound so their resulting sonic booms won't startle the public below or concern them about potential property damage.

Why is the 787 so loud?

The sound comes from the rotary hydraulic motor situated in the wheel well of the jet which turns the drive shaft for the flap drive screw jacks.

Is the 787 still grounded?

While the 787 Dreamliners have not been grounded, the FAA had ordered a halt to deliveries of the widebody jet between May of 2021 and July of 2022 as it looked into questions about quality control during its assembly process.

Does the 787 have a rat?

Did you know that the 787 can deploy a propellor underneath its fuselage? It's called a RAT.

What is the lifespan of a Boeing 787?

The typical lifespan of airliners The composite-driven Boeing 787 Dreamliner is designed for 44,000 flight cycles. These jets can theoretically last several decades with an average of two flight cycles a day. Unlike commercial airliners, fighter jets are unique due to their mission requirements.

Why is the 787 being retired?

The longer the 787s remained on the ground, the more it would cost to get them to fly again, due to the maintenance work required. As a result, they were no longer airworthy.

Is the 787 a success or failure?

The Dreamliner is a successful aircraft, still in production with more than 1600 delivered or on order. The list price for a new Boeing 787-8 is $239 million dollars. Yet even as international travel opens again for these long-range aircraft, two Dreamliners barely ten years old are waiting for the wrecker's ball.

What is the 787 controversy?

The FAA said the leaks could damage critical equipment and lead to a “loss of continued safe flight and landing.” The agency said one airline found wet carpet in the cockpit of a plane and, when it inspected its entire fleet of 787s, found “multiple” planes with leaking faucets.

What are the flaws of the 787 Dreamliner?

The 787's latest problem mirrors production issues discovered over 2020 and 2021 that included improperly fitted shimming that led to paper-thin gaps between surfaces on the Dreamliner's fuselage.
