Abstract:

A systematic research program to investigate the capability of the Lockheed-developed rigid rotor system in the XH-51A helicopters is discussed. The primary objective of the research program was to attain level flight performance at a true airspeed of 200 knots 210 knots true airspeed was actually attained with the Compound XH-51A. Analytical studies, design, fabrication and modification, laboratory tests, wind tunnel and ground tests, and research flight tests of two rotor configurations and a compound version of the helicopter were performed.
