Amendment to Request for Information (RFI) DARPA-SN-24-49
This document is an amendment to a request for information (RFI) issued by the Defense Advanced Research Projects Agency (DARPA)’s Aerospace Projects Office (APO) under the title DARPA-SN-24-49. The RFI seeks information and understanding of component technologies that support the development of high Mach gas turbine (HMGT) engines for integration into turbine-based combined cycle (TBCC) propulsion systems.
The document provides background information on DARPA's vision for reusable hypersonic aircraft attributes and the previous Advanced Full Range Engine (AFRE) program, which explored turbine-based combined cycle engine concepts. The RFI outlines specific details regarding the characteristics and requirements for the HMGT engines, including continuous thrust, sustained cruise Mach number, expected life, altitude range, and fuel type. It also requests information on engine architectures, technology development, notional schedules for design reviews and demonstrations, limitations within the trade space, and additional requirements for a future request for proposal (RFP). Respondents are instructed to submit a single integrated response addressing these areas in a specific format and are provided with submission guidelines.
The amendment introduces specific questions related to HMGT architecture proposals, technology development activities, notional schedules for design reviews and demonstrations, trade space limitations, additional information requirements for a future RFP, concerns about commercial engine militarization, required test facilities and investments, capital expenditures and infrastructure needs. It also provides instructions on how to submit responses in a specific format and mentions the availability of a classified appendix upon formal request.
Additionally, disclaimers and important notes are included regarding the voluntary nature of response submission, non-disclosure of proprietary information obtained as a result of the RFI, and reimbursement policies. The document emphasizes that responses to this RFI do not constitute formal proposals or offers but are intended for information and program planning purposes only.
