The results of a flight research program conducted to investigate methods of improving maneuvering capability of the UH-2 compound helicopter are presented. The effects of wing/rotor load sharing were determined during symmetrical pullup maneuvers using preselected longitudinal cyclic inputs. The wing/rotor load sharing ratio was varied by automatically reducing collective pitch as a function of normal load factor. This was found to increase the attainable maximum normal load factor by 78 percent. Automatic reduction of collective pitch also reduced longitudinal cyclic control sensitivity during maneuvering flight. Roll control augmentation using ailerons was found to be one satisfactory method for imparting acceptable handling qualities for lateral/directional maneuvers in compound aircraft. (Author)
