Similar flying saucer type rotaplane

Abstract

The invention provides a similar flying saucer type rotaplane, and relates to an unmanned aerial vehicle. The invention provides a similar flying saucer type rotor unmanned aerial vehicle which fully utilizes the self-stabilization effect of a top. The rotaplane is provided with a plane body, plane wings, two motors, a variable pitch system and variable pitch propellers, wherein the plane body is connected with the roots of the plane wings, and the inside space of the plane body is used for loading airborne equipment; the plane wings which adopt small short-edge oval wing shapes are used for realizing conversion among the vertical take-off and landing state, hovering state and cruise of fixed wings; the two motors are mounted on the positions of the wing tips of the plane wings on two sides, and the rotating directions of the two motors are consistent; the variable pitch system is used for regulating the propeller pitch of the variable pitch propellers; the variable pitch system is used for regulating the propeller pitch of the propellers to change the thrust direction and the thrust of the propellers, and the switchover between a hovering mode and a cruise mode is realized. The structure is simple, the sensitivity to the center of the gravity of an airplane is weak, and the overall aerodynamic efficiency is high.

Description

technical field [0001] The invention relates to an unmanned aerial vehicle, in particular to a flying-saucer type rotorcraft which can combine vertical take-off and landing of a helicopter, hovering in the air and cruising of a fixed-wing aircraft. Background technique [0002] In order to design an unmanned aerial vehicle that has both the vertical take-off and landing performance of a helicopter and the high-speed and long-range performance of a fixed-wing aircraft, humans have proposed various unmanned aerial vehicles with vertical take-off and landing capabilities, including composite Unmanned helicopters, unmanned aircraft equipped with thrust vector engines, rotating wing unmanned aircraft, tilting ducted propeller unmanned aircraft, tilting rotor unmanned aircraft, etc. [0003] In our country, due to the late start of research on unmanned aerial vehicles, the development of unmanned aerial vehicles with the vertical take-off and landing performance of helicopters, ho...
