The General Electric GE90 is a family of high-bypass turbofan aircraft engines built by ... Problems with GE90 development and testing caused delays in Federal ...
British Airways Flight 2276 was a scheduled international passenger flight from Las Vegas, Nevada, to London, England.On 8 September 2015, the Boeing 777-200ER operating the flight suffered an uncontained engine failure and fire in the left GE90 engine during take-off from Las Vegas-McCarran International Airport, prompting an aborted take-off and the evacuation of all passengers and crew.
The General Electric GE90 has an in-flight shutdown rate (IFSD) of one per million engine flight-hours. [5] The Pratt & Whitney Canada PT6 is known for its reliability with an in-flight shutdown rate of one per 333,333 hours from 1963 to 2016, [6] lowering to one per 651,126 hours over 12 months in 2016.

It is built around an 0.72 scale of the GE90-110B/115B core [1] and contains a Pratt & Whitney fan and low-pressure system design. The competing Rolls-Royce Trent 900 was named as the lead engine for the then-named A3XX in 1996 and was initially selected by almost all A380 customers. However, the GE/PW engine increased its share of the A380 ...
The thrust of a typical jetliner engine went from 5,000 lbf (22 kN) (de Havilland Ghost turbojet) in the 1950s to 115,000 lbf (510 kN) (General Electric GE90 turbofan) in the 1990s, and their reliability went from 40 in-flight shutdowns per 100,000 engine flight hours to less than 1 per 100,000 in the late 1990s.
GEnx on 747-8I prototype. As of 2016, the GEnx and the Rolls-Royce Trent 1000 were selected by Boeing following a run-off between the three big engine manufacturers. The GEnx uses some technology from the GE90 turbofan, [1] including swept composite fan blades and the 10-stage high-pressure compressor (HPC) featured in earlier variants of the engine.
A Boeing 777's two General Electric GE90 engines combine to create a thrust of approximately 200,000 pounds-force (900,000 N), [1] a level of force which is high enough to kill people. [2] To prevent these problems, jet blast deflectors redirect the air stream in a non-dangerous direction, frequently upward.
Development of the engine was abandoned with its problems unsolved, as the war situation worsened for Germany. Later in 1943, the British ground tested the Metrovick F.3 [ 40 ] turbofan, which used the Metrovick F.2 turbojet as a gas generator with the exhaust discharging into a close-coupled aft-fan module comprising a contra-rotating LP ...
