Abstract:

A need was identified for an advanced fighter type inflight simulator. A preliminary design study was conducted to determine the nature and extent of modifications required to convert an existing airplane into an effective, large amplitude six-degree-of-freedom inflight simulator. Conceptual designs of the airplane configuration and variable stability system lead to a preliminary design of a model-following flight control system employing an airborne digital computer to be carried in a modified version of the Agile Eagle II F-4E. The preliminary design involved reconfiguration of the structural, electrical, and hydraulic systems of the airplane. The front and rear cockpits were reconfigured and aerodynamic analyses performed to establish the force and moment capability available to the variable stability system. The performance envelope of the modified airplane was established and the preliminary design study indicated that large amplitude six-degree-of-freedom total mission simulation was realizable with state-of-the-art equipment and techniques.
