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 ...
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 engine is the largest reciprocating engine in the world. The 14-cylinder version first entered commercial service in September 2006 aboard the Emma Mærsk . The design is similar to the older RTA96C engine, but with common rail technology (in place of traditional camshaft , chain gear , fuel pump and hydraulic actuator systems).
The Astazou XX received a third axial stage, raising compression even further to achieve a projected output of 1,075 kW (1,442 hp) in the turboprop application. The XXB derivative, used in the single engine Aérospatiale SA 361H Dauphin , delivered 1,043 kW (1,399 shp).
PSA PureTech engine (Opel, Vauxhall) The GM E-Turbo engine is a gasoline-fueled engine developed by General Motors as part of the company’s next-generation turbocharged engine family. The engine features a start-stop system , gasoline direct injection , an electric water pump and an electric turbocharger wastegate to optimize fuel efficiency .
The aim of the MB-XX program was to develop an engine with "robust operating margins, high reliability, increased thrust, and high specific impulse at an affordable cost". [2] The MB-XX family of engines was intended to be used on new or upgraded upper stages of Boeing's Delta IV and MHI's H-IIA families of launch vehicles.
The engine is propelled by liquid oxygen and anhydrous ammonia, pumped into the engine by turbopumps at a mass flow rate of over 10,000 lb (4,500 kg) per minute. After one hour of operation, the XLR99 required an overhaul. Operating times nearly twice that were recorded in tests, but declared largely unsafe.
The Turbomeca Arrius is one of a family of turboshaft engines for helicopter use, first produced in 1981. As of 2012, some 2,700 units had been sold. As of 2012, some 2,700 units had been sold. Power ranges between 357 kW (479 shp) and 530 kW (716 shp) for different versions.
