RESULTS OF A VTOL PROPELLER-TYPE AIRCRAFT TESTED IN THE SUBSONIC WIND TUNNEL IN A HIGHSPEED CONFIGURATION,

Abstract

The ability of a propeller to develop a force perpendicular to the axis of rotation is the basis for a VTOL aircraft that appears to be capable of hovering, and at the same time to be superior to existing types of VTOL aircraft in high-speed performance. Low-speed wind-tunnel test results for a model indicated a lift-drag ratio of 8 with propellers windmilling in the high-speed configuration. For existing VTOL aircraft, the maximum lift-drag attained in a high-speed configuration is about 5. (Author)
