Abstract
This paper provides an overview of the results of on-going research investigations associated with the XV-15 program. The XV-15 data and an understanding of the technological elements that go into tilt rotor design can provide a series of benchmark points from which to proceed with new design. The work to refine our estimates of vertical-lift performance, the influence of airframe aerodynamics, and the work planned to establish rotor-limiting flight conditions are discussed. An initial look at short takeoff and landing (STOL) performance is provided and the lessons learned and on-going work in aeroelastic testing and data handling is described. Structural loads and stability and control systems work which have applicability to new design efforts are also shown. The paper concludes with some ideas for longer-range generic investigations to advance the state of the art.
