The XV-15 tilt rotor research aircraft has recently completed the contractor flight test program at the Bell Helicopter Textron Flight Research Center, Arlington, Texas. During these development and envelope expansion flights (60 flight hours, 140 flights), the aircraft has been tested up to a maximum true airspeed of 557 km/h (346 mph, 301 knts). Results of the structural characteristics obtained during this testing are presented. Included is a discussion concerning the rotor and airframe loads, natural frequency placements, airframe control system interaction, and wing-rotor-pylon aeroelastic stability. Measured data are compared with predicted values for many cases.
