Advanced Engine Transition Program (AETP)

Abstract

The Adaptive Engine Transition Program (AETP) will design and manufacture multiple adaptive engine prototypes, complete component rig assessments, characterize materials, and inform manufacturing process improvements. 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 program will also 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. AETP test objectives are foundational risk reduction activities for the Next Generation Adaptive Propulsion (NGAP) program providing capability enabling options for Next Generation Air Dominance (NGAD) capabilities. The Adaptive Engine Transition Program (AETP) Program Element is new in FY 2024 and responds to Congressional direction in the 2023 Appropriations Bill and accompanying Joint Explanatory Statement directing the Air Force to maintain separate budget lines for the AETP and Next Generation Adaptive Propulsion (NGAP) efforts. Prior to FY 2023 the entirety of both AETP and NGAP were reported in Project 643608, Advanced Engine Development in PE 0604004F, Advanced Engine Development. This is a congressionally directed administrative realignment to provide increased transparency to Congress and is not a new start. This program element may include necessary emergent or unanticipated civilian pay expenses required to manage, execute, and deliver weapon system capability. The use of such program funds would be in addition to the civilian pay expenses budgeted in program element 0605827F, 0605828F, 0605829F, 0605831F, 0605832F, 0605833F, 0605898F, 0606398F. In FY 2022 0.0 million was expended for civilian pay expenses in this program element, and in FY 2023 2.304 million is forecasted for civilian pay expenses in this program element. 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.
