The report summarizes the preliminary results of a flight research program conducted on the UH-2 compound helicopter for the acquisition of data relative to improving the maneuver capabilities of compound helicopters. The subject program was conducted during the period from 6 October 1965 through 25 January 1966. A total of 25 flights, involving 13.2 hours of aircraft time were conducted. Detailed results and analysis thereof will be included in the final report currently in preparation. Specifically, the program encompassed three areas of technical significance. 1 Wingrotor load sharing during development of load factor buildup in a series of programmed symmetrical pullup maneuvers. 2 Evaluation of automatic rotor load reduction by collective pitch reduction as a function of increasing load factor for a series of programmed symmetrical pullup maneuvers. 3 The use of aerodynamic control surfaces ailerons to augment rotor roll control power.
