Description

The Aerodynamic and Propulsion Test Unit (APTU) is a blowdown facility designed for true temperature aerodynamic, propulsion, and material/structures testing. A vitiated air heater (VAH) provides the required temperature. Liquid oxygen is added in an oxygen mole fraction exists in the test medium. The facility is completely computer-controlled during a run, and very rapidly transitions in pressure and temperature (altitude changes) that can be accomplished at a fixed Mach number. The remote location of the facility plus the straight line ejector exhaust configuration, allows for unique test capabilities. For example, test article hardware separation, i.e. releasable model shrouds, is allowed. Certain types of ammunition/explosive (live-fire testing can be done. The facility is also sited for 10,000 pounds of Class 1.3 explosives.
