Abstract : A ground-based simulation of the CH-47C tandem rotor helicopter was constructed and evaluated. The mathematical model provided a fully coupled, large-perturbation representation of the aircraft which was used in conjunction with a five-degree-of-freedom motion base and a wide-angle point light source visual display. The mathematical model was validated by comparing its static and dynamic characteristics with flight test data. A test pilot flew the simulated aircraft to determine the degree of realism achieved and to evaluate the accuracy with which the CH-47 was represented. Representative data and pilot comments are presented in support of the evaluation.
