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 ...
GE said on Monday it has received orders and commitments for more than 600 GE9X engines, and has delivered eight GE9X test engines and two test spares for Boeing's four 777X test aircraft.
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.
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 ...
