The 27th AIAA International Space Planes and Hypersonic Systems and Technologies Conference, jointly organized with the Italian Association of Aeronautics and Astronautics (A.I.D.A.A), will provide a forum for discussion and exchange of information for attendees from across the globe about leading edge research and development activities associated with space planes and hypersonic atmospheric flight vehicles and the technologies underpinning these capabilities. Presentations will be provided on national programs from Europe, North America, South America, Australia, and Asia and multiple opportunities for international collaboration will be discussed. Technical paper topics include planned and ongoing space plane and hypersonic vehicle programs, advanced launch vehicle and hypersonic atmospheric flight vehicle concepts, commercial space tourism concepts, ground and flight testing techniques, results, and lessons learned, reentry vehicle systems and technologies, aerodynamics and aerothermodynamics of space planes and hypersonic vehicles, guidance and control systems, rocket, ramjet, scramjet, and other advanced propulsion systems, including component technologies (e.g., inlets, combustion systems, fuel injection concepts, ignition and flameholding concepts, nozzles), high-temperature materials, hot structures and thermal protection systems, health monitoring and management technologies, and more. Special panel sessions will be organized around relevant topics of strong global interest.
