Pulsed-Detonation Engine Powers Manned Aircraft Published June 17, 2008 By Thomas Brown, AFRL/RZOP Propulsion Directorate WRIGHT-PATTERSON AIR FORCE BASE, Ohio -- Aviation's first-ever flight test of a manned aircraft powered by a pulsed-detonation engine (PDE) was a success. An AFRL-designed PDE that produced greater than 200 lbs of thrust powered the Long EZ test aircraft, which achieved a speed of 120+ mph and an altitude of 60-100 ft. AFRL propulsion researchers worked alongside experts from industry partner Innovative Scientific Solutions, Inc., to develop and manufacture the engine in-house. The success of this effort is attributable to the active involvement and collaboration of multiple AFRL technical disciplines in completing the range of required activities, including the research and development associated with the PDE and propulsion package; structural support, aero, and acoustical components; pilot exposure limits and acoustic protection; and structural materials. Scaled Composites, Inc., provided vehicle integration and flight test support.
