Abstract:

An analytical study was performed to contribute toward design criteria for the Utility Tactical Transport Aircraft System UTTAS through an analysis of maneuvers to determine effects of the maneuvers on helicopter design characteristics. Maneuverability requirements examined were combinations of maximum flight speeds and maneuvering load factors and sustained high load factors for long periods of time as might be expected in nap-of-the-earth flying. The study included analyses to examine the possibility of gaining maneuver capability at high speeds by adding wings to helicopters. Analysis of results showed no large difference between winged and nonwinged helicopters. Those differences that did emerge, however, were in favor of adding the wing. Whether or not these differences would become more significant through additional design iterations of a particular design is not yet clear.
