The GE90-115B diameter is 128 in (325 cm) while the 777 fuselage is 244 in (620 cm) The GE90's 10-stage high-pressure compressor developed a then-industry record pressure ratio of 23:1 and is driven by a 2-stage, air-cooled, HP turbine. A 3-stage low-pressure compressor, situated directly behind the fan, supercharges the core.
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.

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.
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 ...
As other Rolls-Royce Trent 900 engines also showed problems with the same oil leak, Rolls-Royce ordered many engines to be changed, including about half of the engines in the Qantas A380 fleet. [424] During the aeroplane's repair, cracks were discovered in wing structural fittings, which also resulted in mandatory inspections of all A380s and ...
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.
