A REVIEW OF THE V-22 DYNAMICS VALIDATION PROGRAM

The dynamics validation program for the V-22 is presented relative to the full scale design development and flight test program. Test results are discussed and compared to analytical predictions. Integration of test results into the aircraft development process is also described. The dynamics testing encompasses a broad range of V-22 program elements including the drivetrain, control system, airframe, and rotor. Objectives and results are described for full scale component stiffness, mass, and vibration tests, a series of small scale aeroelastic model tests, drive system critical speed tests, and ground vibration tests of the rotor and airframe.
