The Bell-Boeing V-22 Osprey Tiltrotor is an unique aircraft capable of landing vertically like a helicopter, flying at speeds in excess of 300 KTAS (True Airspeed, Knots) like a turoprop, with the added feature of folding the rotor wing for deployment from shipboard for U.S. Navy/Marines operations. During the development of the V-22 and subsequent 1000+ hours of flight testing, many technical challenges were encountered and overcome. These challenges included: aerodynamic characteristics of the wing, tail buffet, hover performance, hover downwash, structural loads limiting, vibration reduction, landing gear fatigue life, and control law design/Handling Qualities. This paper presents an overview of many of these challenges, discusses the techniques used to perform analysis and flight test, and presents results of the relevant portions of the test program.
