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.
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
Create new operational possibilities
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.
Adaptive three-flow architecture helps reduce fuel expenses and reduce reliance on tankers
To give fighter pilots more of what they need, when they need it
Better heat absorption
Activated via 3D printed heat exchangers (additives)
Thermal management capability
Carbon Reduction Benefits
Reduction of CO2 emissions over the life cycle of the F-35
Can run on US Air Force-approved Sustainable Aviation Fuels (SAF), commonly referred to as “biofuels”
Lighter and more durable
Ceramic Matrix Composites (CMC) are 1/3 the weight of traditional metal parts
Can withstand 500°F more heat
Advantages of the plane
Uniquely designed to fit both F-35A and F-35C without any structural changes to either airframe
So pilots can fly longer in more combat scenarios
To allow pilots more agile tactics and aggressive pursuit
Next Generation Mission Systems
As new mission systems are introduced, the third stream of this engine will bring significant improvements in thermal management
Growth potential of mission systems
The XA100 is a product of GE’s Edison Works, a team dedicated to the research, development and production of advanced military solutions.
