| description abstract | An investigation has been made in the 17-foot test section of the Langley 300-MPH 7- by 10-foot tunnel to determine the longitudinal aerodynamic characteristics of tilt-wing, deflected-slipstream, and combination tilt-wing - deflected-slipstream VTOL configurations in the transition speed range. The results of this investigation are in general agreement with prior related investigations in that although the tilt-wing configuration requires the least power in hovering, the combination tilt-wing-deflected-slipstream configuration has relatively low power requirements throughout the transition speed range. In addition, the longitudinal trim problems of the combination configuration can be handled easily by use of a rearward location of the wing pivot and by properly programing the flap deflection angle with wing tilt angle. | |
