Novel Thermal and Power/Energy Management Architectures for Hypersonic Applications

The Air Force Research Laboratory is seeking industry input on advanced thermal and power management systems for future reusable hypersonic aircraft, with a focus on integrated technologies that replace traditional discrete thermal batteries. The solicitation targets novel architectures for onboard enthalpy management, including power generation, thermal regulation, and combined power-thermal subsystems that leverage innovative fuel technologies and fluid-based cooling solutions beyond conventional onboard fuel. Emphasis is placed on validated modeling, risk-reduction strategies, and mid-term auxiliary power technologies capable of delivering mechanical and electrical energy efficiently in extreme hypersonic environments. This sources-sought notice, identified as RFI-RAP-26-01, is open for responses until August 15, 2026, and is administered by the Department of Defense through the AFRL office at Wright-Patterson Air Force Base in Ohio. The NAICS code 541715 indicates the work relates to research and development in physical, engineering, and life sciences. Primary point of contact is Kenya Martin, with Mitch Boisel as secondary contact, and all submissions must be directed through the SAM.gov portal. The information gathered will inform near-term program requirements and shape mid-term development initiatives for next-generation hypersonic platforms.
