Innovative Aerojet Propulsion System Powers High-Speed Anti-Radiation Demonstration (HSAD) Flight Vehicle SACRAMENTO, Calif., Aug. 19 /PRNewswire-FirstCall/ -- Aerojet, a GenCorp (NYSE: GY) company, announced today that its Integral Rocket Ramjet (IRR) propulsion system which incorporates a nozzleless booster and Variable-Flow Ducted Rocket (VFDR) ramjet technologies, powered a successful air-launched flight vehicle demonstration at White Sands Missile Range in New Mexico. Aerojet's propulsion system, developed for the High-Speed Anti-Radiation Demonstration (HSAD) program, is designed to meet the evolving requirements for a long-range, reactive missile propulsion system with near-term transition to the war-fighter. The HSAD program is sponsored by the Office of Naval Research (ONR) Air Warfare and Naval Weapons Applications (Code 352) with the Naval Air Warfare Center Weapons Division/China Lake (NAWCWD/CL) serving as the program lead and system integrator. For the flight test, the controlled test vehicle (CTV) was successfully rail-launched from a QF-4 drone aircraft, accelerated to supersonic speed, and transitioned to supersonic sustain-phase ramjet flight using Aerojet's VFDR ramjet propulsion system. The VFDR ramjet system features a responsive energy-management capability that provides the CTV with active propulsion throughout the entire sustain flight enabling flight at speeds much higher than standard solid propellant rocket-powered systems. The HSAD system passed a rigorous ground and environmental test program prior to flight. Using flight-weight hardware, these tests demonstrated the transition-readiness of the system. "What makes the HSAD program unique is that this high-performance propulsion system was manufactured and integrated into a war-fighter-class weight and size-compliant missile airframe," said Gariel D. Randolph, PE, HSAD program manager. "We are truly excited about these results and for what they bring to future capabilities." The HSAD all-solid propellant IRR design provides improved Munitions Safety and other benefits over standard solid propellant rockets. The VFDR flight test continues Aerojet's leading role in the development of next-generation tactical propulsion for the U.S. military.
