Advanced target drones will require increased performance and time-on-station to provide adequate simulation of future airborne threats. To be operationally attractive these units should provide realistic simulation over a broad operating envelope, have a low initial cost, and be capable of recovery and reuse. The normal shock inlet ramjet as exemplified by the technology obtained in the surface launched RedheadROADRUNNER Target Drone Program U.S. Army Contract DA-01-021-AML-10991 Z appears to be particularly well suited to this requirements. This volume of the report presents the results of the operation of the normal shock ramjet engine and versions thereof during the wind tunnel test of the Sandpiper Ramjet Target Drone Model. The Beech Aircraft Corporation conducted the test in conjunction with NASA-Langley, Langley AFB, Virginia during the period of November 10 to November 22, 1969. Significant variations in total system drag were observed, varying only the inlet shape and location with respect to the support structure. Author
