Functional Statement

The Hypersonic Airbreathing Propulsion Branch in the Research Directorate at the NASA Langley Research Center performs multidisciplinary research to develop advanced technology for hypersonic airbreathing propulsion systems for aerospace vehicles. The focus is on airframe-integrated engine concepts having high performance over a wide range of flight Mach numbers. Synergistic research provides integrated multidisciplinary methods for design and analysis with both fundamental physics and phenomenological models including effects of turbulence, mixing, finite-rate reactions, fuel injection, and geometry on ignition, combustion, and thrust performance across the speed regime from takeoff to orbital velocity. Innovative concepts for vehicle-integrated airbreathing-engines are developed and evaluated. Complete airframe-engine performance characteristics for both ground-test and flight-test conditions are predicted with experimentally verified analysis methods. Innovative experimental techniques, diagnostics, and facilities for airframe-integrated engines are developed. Tests of complete subscale and large scale engines are made to assess and to improve integrated engine and aero-thermo-structural performance.
