Sweepforward canard flying wing aerodynamic layout unmanned aerial vehicle

Abstract

The invention discloses a sweepforward canard flying wing aerodynamic layout unmanned aerial vehicle, and the unmanned aerial vehicle comprises a vehicle body, main wings, edge strip wings, full-motion canard wings and full-motion vertical tail wings, wherein the main wings, the edge strip wings, the full-motion canard wings and the full-motion vertical tail wings are connected with the vehicle body, and the full-motion canard wings and the full-motion vertical tail wings are arranged at the front end of the vehicle body; the main wings and the edging wings are arranged at the rear end of thefuselage and are of an integrated structure; the flying wing aerodynamic layout, the canard aerodynamic layout and the sweepforward wing aerodynamic layout are fused, so the flying performance of thefixed-wing aircraft is well improved, the contradiction between sweepforward wing aerodynamic divergence and structural quality is solved, the problems that the maximum lift coefficient Clmax of the flying wing layout is too small and the pitching maneuverability is poor are solved, and the problem that a canard layout structure is complex is solved; the maneuvering performance, the loading capacity, the low-speed performance and the like of the canard layout structure are greatly improved, and compared with a conventional aerodynamic layout fixed-wing unmanned aerial vehicle, the effective load of the canard layout structure is increased by 20%, the take-off and landing distance is shortened by 35%, the maximum flight speed is increased by 5%, and the minimum flight speed is reduced by 30%.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a forward-swept duck-type flying-wing aerodynamic layout unmanned aerial vehicle. Background technique [0002] At present, fixed-wing aircraft have conventional layout, tailless layout, three-wing layout, etc., which mainly generate relative motion between the aircraft and the air, and use the air pressure difference between the upper and lower surfaces of the wings to generate lift to make the aircraft fly. It has a large load capacity and high flight speed. However, there are still defects such as poor low-speed performance, poor take-off and landing performance, and insufficient maneuverability that need to be improved urgently. Contents of the invention [0003] Aiming at the defects in the prior art, the present invention provides a forward-swept canard flying-wing aerodynamic layout UAV to improve the low-speed performance, poor take-off and landing perf...
