PREDICTED DYNAMIC CHARACTERISTICS OF THE XV-15 TILTING PROPROTOR AIRCRAFT IN FLIGHT AND IN THE 40-BY 80-FT WIND TUNNEL

摘要

Pretest predictions of the dynamic characteristics of the XV-15 tilt¬ing proprotor aircraft are presented. The data for the aircraft in flight includes: trim conditions, flight dynamics, gust response, aeroelastic stability, and wing response to control. The data for the aircraft in the Ames 40- by 80-Ft Wind Tunnel includes aeroelastic stability, and the wing response to control. The calculations were made for pylon tilt angles of 0° (airplane mode), 0.1° (pylon unlocked), 30°, 60°, and 90° (helicopter mode).
