Abstract:

A piloted simulation designed to examine the effects of terrain proximity and control system design on helicopter performance during one-on-one air combat maneuvering ACM is discussed. The NASA Ames Vertical Motion Simulator VMS and the Computer Generated Imagery CGI systems were modified to allow two aircraft to be independently piloted on a single CGI data base. Engagements were begun with the blue aircraft already in a tail-chase position behind the red, and also with the two aircraft originating from positions unknown to each other. Maneuvering was very aggressive and safety requirements for minimum altitude, separation, and maximum bank angles typical of flight test were not used. Results indicate that the presence of terrain features adds an order of complexity to the task performed over clear air ACM and that a mix of attitude and rate command-type Stability and Control Augmentation System SCAS design may be desirable. The simulation system design, the flight paths flown, and the tactics used were compared favorably by the evaluation pilots to actual flight test experiments. Keywords include Helicopter Rotorcraft Air combat NOENap Of the Earth Flight control systems.
