The first engine to test (FETT) completed its first run in April 2016. [9] This engine completed 375 cycles in 335 hours run-time, which validated the engine design in terms of aerodynamic performance, mechanical system behavior and secondary air system heat management. [10] The GE9X conducted icing tests in Winter 2017. [11]
The first flight with one of these engines took place on 22 February 2007, using a Boeing 747-100, fitted with one GEnx engine in the number 2 (inboard left hand side) position. By fall 2019, General Electric was offering the GEnx-2B, developed for the 747-8, for the revised 767-XF variant based on the 767-400ER, but needed enough volume to ...
General Electric Co said on Monday its GE9X engine for Boeing Co's 777X passenger jet has been certified by the U.S. aviation safety regulator, clearing a hurdle in the planemaker's path to bring ...
General Electric offered to develop the GE90-115B engine, [8] while Rolls-Royce proposed developing the Trent 8104 engine. [9] In 1999, Boeing announced an agreement with General Electric, beating out rival proposals. [8] Under the deal with General Electric, Boeing agreed to only offer GE90 engines on new 777 versions.

The coronavirus crisis compounded that hold up this year as demand for air travel plunged, with Boeing saying in July it was delaying the 777X's entry to service by a year to 2022. GE said on ...
Workshare on the joint venture's first engine, the V2500, was divided between the constituent aero-engine companies. Rolls-Royce based the high pressure compressor on a scale-up of the RC34B eight stage research unit used in the RB401-06 Demonstrator Engine, but with a zero-stage added at the front and a tenth stage added to the rear.

The Rolls-Royce Trent 1000 is a high-bypass turbofan engine produced by Rolls-Royce, one of the two engine options for the Boeing 787 Dreamliner, competing with the General Electric GEnx. It first ran on 14 February 2006 and first flew on 18 June 2007 before a joint EASA/FAA certification on 7 August 2007 and entered service on 26 October 2011.
The type of jet engine used to explain the conversion of fuel into thrust is the ramjet.It is simpler than the turbojet which is, in turn, simpler than the turbofan.It is valid to use the ramjet example because the ramjet, turbojet and turbofan core all use the same principle to produce thrust which is to accelerate the air passing through them.
