Hypersonic Airbreathing Propulsion

Abstract This White Paper examines the current state of Hypersonic Airbreathing Protmlsion attile NASA Langley Research Center and the factors influencing this area of work and its personnel Using this knowledge, the paper explores beyond tile present day and suggestsfuture directions and strategies for the field. Broad views are first taken regarding potentialmissions and applications of hypersonic propulsion. Then, candidate propulsion systemsthat may be applicable to these missions are suggested and discussed. Design tools andexperimental techniques are then described_ and approaches for applying them in the designprocess are considere thernlodynamic, and AeroacousticsCompetency.
