The General Electric XA100 is an American adaptive cycle engine demonstrator being developed by General Electric (GE) for the Lockheed Martin F-35 Lightning II and forms the technological foundation for the company's XA102 propulsion system for the United States Air Force's sixth generation fighter program, the Next Generation Air Dominance (NGAD).
The engine was conceived in 2014, and received US government funding to build a prototype engine in 2016. [2] By 2018, the USAF had committed US$295 million of government funding to develop the engine and build an initial engine prototype, while Aerojet will put US$86 million of private capital into the project through the prototype build.

The Pratt & Whitney XA101 is an American adaptive cycle engine demonstrator being developed by Pratt & Whitney for the Lockheed Martin F-35 Lightning II and form the technological foundation for the company's XA103 propulsion system for the United States Air Force's sixth generation fighter program, the Next Generation Air Dominance (NGAD).
After its partnership with Rolls-Royce fell apart, the Colorado-based jet startup unveiled its Symphony engine design — and its new design team — on Tuesday in Greensboro.
The 1973 oil crisis increased oil prices in the 1970s, which caused engine manufacturers to research new technologies to reduce fuel burn, including open rotor (also known as propfan) engines. However, none of those designs made it to production aircraft, mostly due to decreasing oil prices and concerns over the high noise footprint of those ...
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]
SpaceX has developed two kerosene-based engines through 2013, the Merlin 1 and Kestrel, and has publicly discussed a much larger concept engine high-level design named Merlin 2. Merlin 1 powered the first stage of the Falcon 1 launch vehicle and is used both on the first and second stages of the Falcon 9 and Falcon Heavy launch vehicles. The ...
The Stellantis Hurricane GME-T6 engine is a twin-turbocharged straight-six engine produced by Stellantis since November 2021 at their plant in Saltillo, Mexico, and announced publicly in March 2022. It debuted with two versions, one of standard output (SO) and one of high output (HO), both featuring a start-stop system but designed for more ...
