In February 2012, GE announced studies on a more efficient derivative of the GE90, calling it the GE9X, to power both the -8 and -9 variants of the new Boeing 777X.It was to feature the same 128 in (325 cm) fan diameter as the GE90-115B with thrust decreased by 15,800 lbf (70 kN) to a new rating of 99,500 lbf (443 kN) per engine.

The 777-8 provides seating for 395 passengers and has a range of 8,745 nmi (16,196 km; 10,064 mi) while the 777-9 has seating for 426 passengers and a range of over 7,285 nmi (13,492 km; 8,383 mi). The 777X program was proposed in the early 2010s with assembly at the Boeing Everett Factory and the wings built at a new adjacent building.
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]
First delivery of the 777-9 has since been pushed back to 2026, followed by the smaller 777-8 and a freighter version later in the decade. Boeing's other 777X airline customers include Emirates ...
The company said it conducted its first flight on Friday night after receiving Type Inspection Authorization (TIA). The development is a boost for Boeing, which has been grappling with production ...

In 2018 Honeywell had a 65% share of the airliner APU market and is the sole supplier for the Airbus A350, the Boeing 777 and single-aisle airliners: the Boeing 737 MAX, Airbus A220 (formerly Bombardier CSeries), Comac C919, Irkut MC-21 and Airbus A320neo after Airbus removed the Hamilton Sundstrand APS3200 option.
The 280 cm (110 in) fan has 26 wide chord titanium fan blades. [10]The Trent 800 is an axial flow, high bypass turbofan with three coaxial shafts. The fan is driven by a 5-stage axial LP turbine (3300 rpm), the 8-stage IP compressor (7000 rpm) and the 6-stage HP compressor (10611 rpm) are each powered by a single stage turbine.
