A. Mission Description and Budget Item Justification
The Advanced Engine Development Program enables demonstration of advanced turbine engine prototypes. This program is maturing fuel efficient adaptive engine
component technologies and reducing associated risk in preparation for next-generation propulsion system development for combat aircraft applications. Adaptive
engine technology enables next generation combat aircraft capabilities by combining the efficiency of high bypass turbofans used by commercial airlines with the
performance demanded of military fighter engines. This technology has undergone initial development under the auspices of the Air Force Research Laboratory through
the Adaptive Engine Technology and Adaptive Engine Technology Demonstrator programs.
In addition, this program element may include necessary civilian pay expenses required to manage, execute, and deliver advanced engine capabilities. The use of such
program funds would be in addition to the civilian pay expenses budgeted in program element 0605831F.
This effort is in Budget Activity 4, Advanced Component Development and Prototypes (ACD&P), because efforts are necessary to evaluate integrated technologies,
representative modes or prototype systems in a high fidelity and realistic operating environment.

C. Accomplishments/Planned Programs ($ in Millions)
FY 2019 FY 2020 FY 2021
Title: Adaptive Engine Transition Program
Description: The Adaptive Engine Transition Program (AETP) will design and manufacture multiple flight-weight adaptive engine
prototypes, complete component rig assessments, characterize materials, and inform manufacturing process improvements.
The program will demonstrate adaptive engine technology can be scaled to meet military fighter engine size requirements, while
ensuring appropriate manufacturing and technology readiness levels by producing flight-weight prototypes. The prototype engines
will demonstrate fuel efficiency increases, thrust increases, and new component technologies by performing sea-level, altitude,
and durability assessments across multiple power settings. These assessments will provide data to quantify the capability and
reduce risk in areas such as thermal capacity, reliability, and supportability, among others.
The FY 2021 Budget Justification Exhibit has been updated to reflect the breakout of the FY2019 through FY 2021 Next
Generation Adaptive Engine (NGAP) funds from the AETP effort to increase transparency to Congress. This breakout will be
reflected in future Budget Exhibits.
FY 2020 Plans:
Continue component rig activities. Continue technology, affordability, and sustainability studies. Continue engine fabrication.
Begin engine assessments. Continue additional airframe integration/adaptive propulsion design efforts. More details can be
provided in an appropriate forum.
FY 2021 Plans:
Complete component rig activities. Complete technology, affordability, and sustainability studies. Complete engine fabrication and
assessments. Complete airframe integration/adaptive propulsion design efforts. More details can be provided in an appropriate
forum.
FY 2020 to FY 2021 Increase/Decrease Statement:
FY 2021 decreased compared to FY 2020 by $214.018 million. Funding decreased due to completion of numerous activities
leading up to the final prototype ground-run demonstrations in FY 2021.
589.729 447.449 233.431
Title: Next Generation Adaptive Propulsion
Description: The Next Generation Adaptive Propulsion (NGAP) effort will design and perform component risk reduction
for flight-weight adaptive engine prototypes for next generation fighter applications. NGAP will demonstrate that adaptive
engine technology can be scaled to meet next generation military fighter engine size requirements, while ensuring appropriate
manufacturing and technology readiness levels.

E. Acquisition Strategy
For Adaptive Engine Transition Program, the Air Force has awarded two limited source, cost plus incentive fee contracts to General Electric and Pratt & Whitney due to
their unique qualifications to design a high performance, flight-weight adaptive turbine engine in the thrust class for AETP. Incentive categories include engine weight,
performance factors, and maintainability and supportability, with specific metrics for each area incentivized. The government agency responsible for managing this
program is the Air Force Life Cycle Management Center, Propulsion Directorate, Wright-Patterson Air Force Base, Ohio.
