Modeling The OH-6A Using FLIGHTLAB And Helicopter Simulator Considerations

Recent technological advancements in robust computer hardware, simulation modeling technology, newer electronic actuators and advanced computer graphics have enabled manufacturers to develop low cost, affordable helicopter flight simulators. This thesis presents detailed information on the U.S. Army Hughes OH-6A “Cayuse” helicopter together with a comprehensive model of the aircraft suitable for high fidelity simulator modeling. Fidelity of the model is obtained through use of commercial off-the-shelf software that is incorporated in a low-cost flight simulator, which is marketed as FLIGHTLAB. The FLIGHTLAB development system facilitates rapid design and analysis of a high fidelity helicopter model using non-linear dynamic modeling techniques. The simulator model of the Hughes OH-6A helicopter is presented and its fidelity is compared to actual fight test data conducted at the U.S. Naval Test Pilot School in Patuxent River, MD. Advancements in electromagnetic actuators and visual rendering systems are also presented to provide insight into the direction simulator technology is progressing.
