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 General Electric XA102 is an American adaptive cycle engine demonstrator being developed by General Electric (GE). It is competing with the Pratt & Whitney XA103 as the powerplant for the United States Air Force's sixth generation fighter program, the Next Generation Air Dominance (NGAD).
Cut-away view of a prospective ADVENT engine. The Adaptive Versatile Engine Technology (ADVENT) program was an aircraft engine development program run by the United States Air Force with the goal of developing an efficient adaptive cycle, or variable cycle engine for next generation military aircraft; initial demonstrators were expected to be in the 20,000 lbf (89 kN) thrust class.
Cut-away view of a prospective Adaptive Versatile Engine Technology (ADVENT) engine. A variable cycle engine (VCE), also referred to as adaptive cycle engine (ACE), is an aircraft jet engine that is designed to operate efficiently under mixed flight conditions, such as subsonic, transonic and supersonic.
The three-stream adaptive cycle design can direct air to the bypass third stream for increased fuel efficiency and cooling or to the core and fan streams for additional thrust and performance. The engine thrust has not been disclosed, although it is speculated by aviation reporters to be in the 35,000–40,000 lbf (156–178 kN) thrust class. [2]

The J33 was originally developed by General Electric as a follow-on to their work with the designs of Frank Whittle during World War II.Their first engine was known as the General Electric I-A, but after major changes to adapt it to US production and to increase thrust, it started limited production as the I-16 in 1942, the 16 referring to its 1,600 lbf (7.1 kN) thrust.
General Electric (GE) began developing the GE37, which would become basis of the XF120 and YF120, for the Joint Advanced Fighter Engine (JAFE) program in the early 1980s aimed at supplying the powerplant for the Air Force's Advanced Tactical Fighter (ATF) and the Navy's Advanced Carrier-Based Multirole Fighter (VFMX); JAFE was later renamed the ATF Engine (ATFE) following VFMX's cancellation.
