The JANNAF 39th Airbreathing Propulsion Subcommittee sessions will discuss technical problems and issues associated with airbreathing propulsion systems for applications to missiles, launch vehicles, aerospace planes, and remotely piloted vehicles. These include technology, components, and engines within the turbojet, ramjet, scramjet, and combined cycle families. Session topics may include characterization of system performance, engine cycle analysis and testing, engine design, engine/airframe integration, thermal management, fluid and structural mechanics, advanced engine structures and materials, fuel control systems, and characterization of advanced airbreathing fuels.
Areas of interest included in the Call for Papers are:

Basic Technology and System Applications: Turbopropulsion technologies related to missiles, drones, and UAV systems for both subsonic and supersonic mission applications. Areas of interest include, but are not limited to, the following: innovative architectures, performance and operability, system integration, fuels, structures, materials and manufacturing, controls, thermal management, modeling and simulation, component level testing, ground/flight test experiments, and system-level assessments. Papers in this mission area will be considered for joint APS/CS sessions.

Ramjets: Welcome are papers describing either experimental or theoretical studies related to solid, liquid, and gaseous (ducted rocket) fueled ramjet systems or the constituents thereof. Authors are welcome to submit papers addressing ramjet and ducted rocket technologies at the component, section, or system level. By example, topics at the component level include techniques for mixing enhancement, active and passive control, plume signature reduction, instability and testing techniques. Papers describing modeling and simulation studies of ramjets or their subcomponents are encouraged. Fuel development for subsonic, air-breathing applications continues to be an active area of research within the ramjet propulsion mission area.
Mode Transition: Papers that address mode transition either to or from that of conventional ramjet operation, e.g., boost to conventional ramjet or subsonic to supersonic combustion are welcome. Papers should emphasize the technology that assists in this transition.
Technologies with a Ramjet Application: Authors are encouraged to submit papers that address technologies applicable to ramjet systems, e.g., manufacturing technologies and fabrication techniques, etcetera. Papers need not be associated with a particular system but should be applicable to materials associated with such vehicles and their corresponding flight environment.

Fundamental and Applied Technology: Combined and advanced cycle airbreathing propulsion and engine controls technology and systems. Of particular interest is numerical and experimental research regarding: 1) Aerodynamic, thermodynamic, and structural integration of multiple propulsive cycles and the manner of mode transition between cycles; 2) Methods of broadening the flight Mach number range of gas turbine and dual-mode ramjet cycles to facilitate mode transition; 3) Exploration of airbreathing cycles other than the Brayton cycle; and 4) System-level evaluations to include the choice of fuels, propulsion-airframe integration, and payoff assessments. Papers in this mission area will be considered for joint APS/CS sessions.
