Airbreathing Propulsion (APS) Subcommittee

Technical Objectives

The general technical objectives of this subcommittee involve standardization of nomenclature, analytical techniques and test procedures, coordination of interagency programs, promotion of technical information and data exchange, and the solution of propulsion problems in present and future systems.



The scope of the Airbreathing Propulsion Subcommittee addresses technical problems and issues associated with airbreathing systems over the entire range of atmospheric propulsion. Airbreathing topics include technology, components and engines of the turbojet, ramjet, scramjet, and combined or mixed cycle family applied to missiles, launch vehicles, hypersonic cruise vehicles, and remotely piloted and uninhabited vehicles. Mixed cycle engines include air turborockets, turboramjets, ejector ramjets, ducted rockets (ramrockets), air augmented rockets and others. Aircraft applications, nuclear propulsion, and fundamental combustion studies are specifically excluded from the subcommittee scope of activities. Characterization of system performance is done through engine cycle analysis, CFD modeling and simulation, and engine testing and validation. Engine design issues are examined from propulsion system and airframe integration, active combustion control, through structures and materials, to characterizing advanced airbreathing fuels.
