The sub-scale (15-foot) HySID configuration version was developed in response to a requirement for an unmanned, autonomous, hydrocarbon-fueled, Mach 0 - 7 hypersonic systems flight test demonstrator.  The mission requirements included take-off and landing operations, as well as acceleration, cruise, and descent.  Modularity to support the testing of alternate low and high-speed propulsion systems, other high-speed vehicle technologies, and the ability to carry cryogenic fuels was also required.

The overall objective of this effort (Phases I, II, and III) is to fly the HySID subscale shape first at subsonic speeds, and then through transonic speeds, utilizing the appropriate SWB micro-turbojet system [(3) SWB-100 turbojet engines].  The purpose of the present Phase II effort is to complete fabrication of a 15-ft HySID configuration remotely piloted vehicle (RPV) and perform initial flight tests at subsonic speeds.  Flight testing is tentatively scheduled for late Spring/early Summer of 2001 to be performed by SWB Turbines staff.  The vehicle will be piloted by SWB Turbines Consultant Robert Vess.
