The Feasibility of the Jet-Flap Rotor as a Lift Generator for Vertical Takeoff and Landing Aircraft.
Authors: John Charles Ball; NAVAL POSTGRADUATE SCHOOL MONTEREY CALIF |

Abstract: The objectives of this study were first to determine the effectiveness of the jet-flap rotor relative to other lift generators, and second to examine the potential effectiveness of the jet-flap rotor in a tactical VTOL aircraft. It was found that the jet-flap rotor has a high theoretical potential, but at present is the least-developed of the lift generators considered. The jet-flap rotor was found to be unattractive as a means of providing vertical lift, except when a long hover duration is necessary. With regard to weight considerations alone, the jet-flap rotor was found to be inadvisable for use in a tactical VTOL aircraft. However, its benign downwash characteristics could make the jet-flap rotor advantageous if high downwash velocities and temperatures could not be tolerated. (Author)
