Piloted Simulation in the Development of the XV-15 Tilt Rotor Research Aircraft

R. L. Marr / G. B. Churchill

The effective use of simulation in the XV-15 preliminary design was demonstrated. All primary program objectives were met. The initial simulation evaluation during the source evaluation board proceedings contributed significantly to performance and stability and control evaluations. Subsequent simulation periods provided major contributions in the areas of control concepts, cockpit configuraiton, handling qualities, pilot workload, failure effects and recovery procedures. The fidelity of the simulation also provided a valuable pilot training aid as well as a means of evaluating the tilt rotor concept for various military and civil missions. Simulation continues to provide valuable design data for refinement of automatic flight control systems and design support for future tilt rotor applications. Throughout, fidelity has been a prime issue and has resulted in unique data and methods to validate and update the tilt rotor math model. Researchers participation from contractor and government agencies in the development of this simulation effort has led to a generic tilt rotor simulation capability on numerous facilities.
