Abstract:This paper describes some of the criteria used in designing the HueyCobra for the helicopter attack mission. A new concept in stability and control augmentation systems is described in detail and applied to the HueyCobra. Developmental flight-test problems and their solutions are described. Maneuverability criteria and theory are discussed and important maneuverability parameters of the HueyCobra and several other helicopters are compared. Some aspects of the helicopter flying qualities specification, MIL-H-8501A that are no longer adequate for high-speed helicopters are discussed. Alternate criteria are suggested which emphasize the importance of the mission on the Selection of criteria. The overall flying qualities are presented and compared with contemporary criteria.
