Aerospace Testing Seminar (ATS): (Oct) hosted by Aerospace Corporation
AIAA: (Thermophysics (June) and Aerospace Sciences (January) are the most relevant for us) — highly academic in nature but usually good papers.
ASME Heat Transfer: (July) American Society of Mechanical Engineers
USACA Annual Conference on Composites, Materials, and Structures: (Jan) All ITAR sessions, mostly hypersonic and high-temperature materials.
Space Cryogenics Workshop (July, biannual) workshop with papers specific to space-based cryogenic applications and research
Joint Army Navy NASA Air Force, JANNAF: (December: Combustion/Airbreathing Propulsion/Propulsion Systems Hazards/Modeling and Simulation Joint Subcommittee, & March: Nondestructive Evaluation/Rocket Nozzle Technology/Structures and Mechanical Behavior Joint Subcommittee)
AIAA / ICES, International Conference on Environmental Systems: (June) – usually heavily international, less academic.
SAMPE, Society For the Advancement of Material and Process Engineering: (May/Sept) Materials & processing oriented. Heavily populated with materials vendors: carbon fibers, aluminum – metal matrix, etc. Papers are not as academic, very practical.
Spacecraft Thermal Control Technology Workshop: (March) hosted by Aerospace Corporation
Nuclear and Emerging Technologies for Space (NETS) (Feb) hosted by the American Nuclear Society’s Aerospace Nuclear Science & Technology Division (ANSTD)
TFAWS: (Aug/Sept) Thermal and fluids workshop hosted by a NASA Center (hosting rotates by year), offers software training, short courses, vendor displays and paper sessions. A great way to meet others in the thermal/fluids community.
