The primary performance differentiator between the HTF and other hypersonic free jet facilities is its non-vitiated (clean) flow. The HTF is a blow-down, non-vitiated, free jet wind tunnel that is capable of simulating Mach 5, Mach 6, and Mach 7 true enthalpy conditions. Due to the high-energy nature of the facility, it is operated remotely from a control room approximately one-quarter mile from the actual facility. Its experimental infrastructure includes a shop area for fabrication of materials for facility subsystems and assembly of customer hardware. Facility Overview Direct connect configuration of the interior of the Hypersonic Tunnel Facility (HTF).ĭesigned to conduct research, development, and acceptance testing of hypersonic airbreathing propulsion systems, the Hypersonic Tunnel Facility (HTF) is a fully self-contained facility.
Armstrong Test Facility (ATF) located in Sandusky, OH, originally designed to test nuclear thermal rocket nozzles, is a hypersonic (Mach 5, 6, and 7) blowdown, nonvitiated freejet facility that tests large-scale hypersonic air-breathing propulsion systems.
