The background of a program focused on extending its moving base research flight simulator facility with real time helicopter simulation, and its objectives and the approach to accomplish them are discussed. The available hardware systems (e.g., a multiprocessor computer system, a model board/television camera visual system, and motions systems) in combination with the development software contain sufficient capabilities to establish a helicopter research facility for research concerning handling qualities, digital control laws, man machine interface, etc. The procurements expected in the near future, a generic helicopter cockpit and a computer generated imagery visual system, will not only support but also increase these capabilities. Specific helicopter software modules ware developed and tested separately. At present, the modules are integrated within the comprehensive flight simulation program and off line validation are in progress. The helicopter software modules developed are outlined and suggestions for further improvements are given.
