Re-usable research vehicle

This X-30 RSRV (re-usable suborbital research vehicle) will be carried under the lower fuselage of a modified Tri-Star aircraft and released at an altitude of approximately 40,000 ft. The RSRV is attached to the aircraft by special hooks which are hydraulically activated to effect release at the required altitude. So that the Launch Panel Officer has a continuous indication of the restraint force at each hook throughout the flight, a strain gauge is installed on each hook. The strain gauges were installed by the Measurements Group UK at the request of Marshall Aerospace who modified the Tri-Star. Orbital Science Corporation is Marshall’s client.
