High Speed Systems Integ & Demo
Abstract
This project develops and demonstrates, via modeling, simulations and analysis (MS&A), and ground and flight tests, advanced technologies that enable future high speed/hypersonic weapons and platforms (vehicles). System level integration brings together air vehicle technologies (including high speed structural solutions) with avionics, propulsion, warheads and other aerospace subsystems for demonstration in a near-realistic operational environment. Integration and technology demonstrations reduce the risk and time required to transition technologies into operational systems. Digital engineering is utilized to develop and deliver an integrated digital environment (IDE) to assess technology, evaluate its impacts, and make capability-focused investment decisions. One key technology is a scramjet/dual-mode ramjet propulsion system. The development, integration, and demonstration of this propulsion system to a readiness level appropriate for full integration with other engine cycles (including turbine and rocket-based) is critical to provide the Air Force with revolutionary military capabilities. Multi-cycle engines will provide the propulsion systems for possible application to support aircraft and weapon platforms. Efforts include: scramjet flow-path (from inlet to nozzle) optimization to enable operation over the widest possible range of Mach numbers; active combustion control to assure continuous positive thrust (even during mode transition); robust flame-holding to maintain stability through flow distortions; maximized volume-to-surface area to minimize the thermal load imposed by the high-speed engine; thermal management systems (for example fuels, structural considerations, and power) play a vital role in scramjet and combined cycle engines, including considerations for protecting low speed propulsion systems (e.g., turbine engines) during hypersonic flight. In FY 2025, the entirety of PE 0603216F, Aerospace Propulsion and Power Technology, Project 635098 Advanced Aerospace Propulsion, is transferred to PE 0603211F, Aerospace Technology Dev/Demo, Project 634926 High Speed Systems Integ & Demo.
