The overall structural design of the culverted flyer layout aircraft and the angle-of-view characteristics

Abstract

In view of the advantages of both vertical landing and flying wing layout aircraft, the culverted rotor has the advantages of a larger thrust-to-weight ratio and higher net lift efficiency. The culverted rotor is used to achieve a vertical landing. Landing of the aircraft will be an important research direction in the future. This type of aircraft can realize the automatic closing of the upper and lower culvert closing plates when the vertical landing and landing state is changed to the high-speed level flight state. This paper gives a detailed overview of the overall mechanical design of this new culverted wing layout aircraft. Then it analyses that the wing surface aerodynamic characteristics of the culverted wing layout aircraft change abruptly before and after the transition state. This is because the closure of the closing plate achieves a rapid change in the angle of orientation to avoid the degradation of the aircraft’s aerodynamics. The angle of orientation of the wing should be calculated before and after the two states.
