XA100 adaptive cycle engine for the F-35 aircraft



Sized and optimized for the F-35

A new era of combat propulsion

As we enter a new phase of near-peer competition, more capability is needed from the engines that power our military’s aircraft. GE is ready to meet this need with the XA100 engine. Designed, built and tested with the US Air Force, the XA100 is the world’s first adaptive three-stream flight weight engine. The XA100 engine represents the next generation of propulsion for the F-35.

Unparalleled performance,
validated by test

GE’s XA100 became the world’s first three-stream, flight-weight adaptive cycle engine to start in December 2020 before launching tests on a second engine in August 2021.

GE’s engine is uniquely designed to fit both the F-35A and F-35C without any structural changes to either airframe, allowing for better range, acceleration and cooling power of the aircraft to accommodate next-generation mission systems, while ensuring durability and improved readiness.

Why now is the time for GE’s XA100

The future of the F-35 is adaptive

General Electric

Create new operational possibilities

Adaptive Engine

This variable cycle motor provides a high thrust mode for maximum power and a high efficiency mode to extend mission range. Automatic switching between these modes radically transforms mission capability and enables unrestricted operations.

Thermal management capability

Advantage of the third component

This advanced capability provides an additional source of cooled air to improve propulsion and fuel efficiency. Most importantly, it allows for a step change in thermal management capability to accommodate next-generation mission systems and provide higher thrust in and out of supersonic flight.

Advanced materials and components

Ceramic matrix composites (CMC) can withstand temperatures of hundreds of degrees while being lighter and more durable than traditional materials. The use of additive manufacturing has made it possible to lighten the weight of the engine, reduce the number of parts and improve the ease of maintenance.

Fuel savings

Adaptive three-flow architecture helps reduce fuel expenses and reduce reliance on tankers
