An experimental investigation was carried out to determine the effect of subsonic Mach number on the drag characteristics of a high-speed wingless and winged helicopter when equipped with two different rotor head fairings. A simulated unfaired rotor head was provided as a basis for comparison. Test were performed using a 1/9th scale model of a 60,000-pound class helicopter design. Data acquired included gross model force and rotor head force data, wing and pylon surface pressures, and tuft photos.
