What is the problem with the bulkhead of the 787?

What is the problem with the bulkhead of the 787? What is the problem with the bulkhead of the 787? The inspection found gaps that exceeded maximum tolerance and forced Boeing to the decision that the forward pressure bulkhead on every undelivered aircraft would need to be removed and replaced.

Which planes have no horizontal stabilizer?

A tailless aeroplane has no separate horizontal stabilizer.

Is a 787 Dreamliner a good plane?

Excellent design choices all around. Better sleep on long flights. Because the 787 is pressurized at about 6,000 feet rather than 8,000 feet, you'll breathe easier. More oxygen in your lungs means better sleep, less chance of headache, no difficulty breathing (flying at altitude is like sleeping at a ski resort).

What is the problem with the 787 Dreamliner fuselage?

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.

Why is Boeing 787 so quiet?

To combat the sound of jet-blast from the rear of the engine, Boeing, General Electric, and NASA developed serrated edges called chevrons for the back of the nacelle and the engine exhaust nozzle. The chevrons reduce jet blast noise by controlling the way the air mixes after passing through and around the engine.

Is Boeing 787 a failure?

Jun. 28—After debuting in 2011, Boeing Co.'s 787 Dreamliner has become popular among the world's airlines. But heightened scrutiny both inside and outside the company in recent years has revealed a number of production flaws and largely prevented it from delivering new Dreamliner jets for nearly two years.

Why is a Boeing 787 Dreamliner grounded?

On January 17th, 2013, the FAA ordered the entire 787 fleet across all airlines to be grounded, and the NTSB launched an investigation. The culprit was eventually identified as a lithium-ion battery. A cell within the battery was believed to have short-circuited, causing what is known as a thermal runaway.

What is the new issue with Boeing 787?

The problem involves a fitting for the 787's horizontal stabilizer installed by a Boeing production facility in Salt Lake City, Utah, the company said. The horizontal stabilizer, located at the base of an aircraft's tail, allows a plane to maintain longitudinal balance while flying.

What are the defects of the 787 Dreamliner?

It's the latest in a long and very expensive litany of 787 quality woes. The affected attachment fitting is provided by a supplier and installed on the horizontal tail at Boeing's manufacturing facility in Salt Lake City. The defect is a small, paper-thin gap in the attachment, Boeing said.

Why did Boeing stop making the 787?

“In reviewing certification records, Boeing discovered an analysis error by our supplier related to the 787 forward pressure bulkhead,” said the company, referring to the portion of a plane at its nose that maintains the pressurized conditions in the cabin.

Why are Dreamliners being scrapped?

They were part of a group of 35 Boeing 787s that were grounded because of problems with their engine blades, which were cracking or corroding prematurely.

Why 787 is better than A350?

The Bottom Line: The Airbus A350-900 and Boeing 787-9 are very similar aircraft, suited for similar missions. As one would expect, the slightly larger A350-900 has a seat-mile cost advantage, while the 787-9 has an advantage in cost per block hour. These aircraft are competitive, and nearly tie in economic performance.

What is the lifespan of the 787 Dreamliner?

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 Dreamliner so comfortable?

The Air Inside The cabin pressure on the 787 is higher and the humidity higher than other airplanes. Basically, passengers on board will feel like they are at an altitude of 6,000 feet, 2,000 feet lower than a standard flight.
