GE Initiates Testing on Second XA100 Adaptive Cycle Engine

GE has initiated testing on its second XA100 adaptive cycle
engine as part of the U.S. Air Force’s Adaptive Engine Transition
Program (AETP). Testing began on August 26, 2021, at GE’s Evendale,
Ohio, altitude test facility. This is GE’s final planned prototype
engine as part of AETP.
Full-scale prototype engine testing in the AETP program is the
capstone of a multi-year technology maturation and risk reduction
effort to bring an adaptive cycle engine to full maturity in close
partnership with the U.S. Air Force. GE’s first XA100 engine tests
began in December 2020, marking the world’s first ever run of a
flight-weight three-stream adaptive cycle engine. Tests
successfully validated the engine’s ability to deliver
transformational propulsion capability to current and future
fighter aircraft. Engine prototypes assembled as part of AETP are
designed to fit and integrate directly into the F-35.

The XA100-GE-100 engine combines three key innovations to
deliver a generational change in combat propulsion performance:
- An adaptive engine cycle that provides both a high-thrust mode
for maximum power and a high-efficiency mode for optimum fuel
savings and loiter time
- A third-stream architecture that provides a step-change in
thermal management capability, enabling future mission systems for
increased combat effectiveness
- Extensive use of advanced component technologies, including
ceramic matrix composites (CMC), polymer matrix composites (PMC),
and additive manufacturing
These revolutionary innovations increase thrust 10%, improve
fuel efficiency by 25%, and provide significantly more aircraft
heat dissipation capacity, all within the same physical envelope as
current propulsion systems. The XA100’s improved fuel efficiency
provides significant reduction in carbon emissions. The engine will
also operate on any U.S. Air Force-approved biofuels.
“The U.S. Air Force and Congress have invested more than $4
billion in adaptive cycle engine development over the past 14 years
to mature its associated technologies. We’re confident this phase
of the program will significantly reduce risk and prepare GE for a
low-risk engineering and manufacturing development program,
consistent with Air Force objectives,” said David Tweedie, GE
Edison Works’ General Manager for Advanced Combat Engines. “Getting
our second prototype engine into the test cell means we’re one step
closer to getting this transformational technology into the hands
of the warfighter.”
Testing on the second XA100 will allow GE to continue gathering
high-quality test data and further mature the engine’s advanced
componentry and revolutionary three-stream design. Once first phase
testing is complete in Evendale, GE plans to test the engine at the
U.S. Air Force’s Arnold Engineering Development Complex (AEDC) to
finish out all planned AETP testing activities.
“The Air Force has put a tremendous amount of rigor into the
AETP product requirements. We believe we’re delivering on those
requirements, and a big reason for that is our close collaboration
with the Air Force. Our partnership there has been a critical
factor in our success,” Tweedie added.
The XA100 is a product of GE Edison Works, a business unit
dedicated to the research, development, and production of advanced
military solutions. This business unit has full responsibility for
strategy, innovation, and execution of advanced programs.
