Integration of a real-time parallel transputer-based helicopter simulation with real flight control hardware

A transputer-based parallel implementation of a helicopter model allows real-time operation with a high level of fidelity. Such an implementation, using a highly configurable transputer network has now been developed. Our model, of the EH101 helicopter, has a five-bladed main rotor, with twelve elements modelled for each blade. The subject of this paper is the integration of this model with production flight control computers as used on the EH101, a hardware-in-the-loop simulation
