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]
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 ...
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 ...
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 ...
The higher thrust GE90-110B1 and -115B engines, in combination with the second-generation 777 variants -200LR and -300ER, were primary reasons for 777 sales being greater than those of the rival A330/340 series. [19] Using two engines produces a typical operating cost advantage of around 8–9% for the -300ER over the A340-600. [20]

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.
General Electric Company, doing business as GE Aerospace, [4] is an American aircraft engine supplier that is headquartered in Evendale, Ohio, outside Cincinnati.It is the legal successor to the original General Electric Company founded in 1892, which split into three separate companies between November 2021 and April 2024, adopting the trade name GE Aerospace after divesting its healthcare ...
