Abstract: A model-controlled-system method for airborne simulation that overcomes some disadvantages of present variable-stability airplanes has been studied analytically and proved feasible. This new approach has been a natural outgrowth of the development of model adaptive control systems and uses a similar model-following concept. Satisfactory matchmg of specific motion parameters can be obtained for model frequencies at least up to the natural frequency of the base airplane used for the airborne simulator. Time histories from analog studies of a simulator using a model-controlled system in a small subsonic jet transport and using a hypothetical supersonic transport as the model are presented as examples of the simulation performance expected. In a general discussion of airborne simulation, it is observed that the motion of a specific aircraft cannot be matched completely with an airborne simulator, except at certain specific conditions, if the number of independent control devices for angular and linear motion is less than the number of corresponding degrees of freedom to be simulated. However, airborne simulators can be valuable research and pilot-training tools through proper choice of the motion parameters to be matched and by tailoring the program to the particular simulator used.
