Rotor Performance of an Isolated Full-Scale XV-15 Tiltrotor in Helicopter Mode

Abstract

The performance of a full-scale XV-15 rotor operating in low-speed helicopter-mode flight on a rotor test apparatus was measured in the NASA Ames 80- by 120-Foot Wind Tunnel. The hub-tare-corrected results yield essentially isolated rotor performance minimally affected by the presence of the rotor test apparatus. These data comprise the most extensive data set published for a full-scale tiltrotor in low-speed helicopter-mode flight and can be used for validation of analytical techniques for the prediction of tiltrotor performance.
