Abstract

The invention discloses an air vehicle, which comprises a machine body, two front wings symmetrically arranged on the head part of the machine body, and two main wings symmetrically arranged on the tail part of the machine body. Each front wing is a lower single wing; each main wing is an upper single wing; the wing taper ratio of each main wing to each front wing is 1 to 1, and no weep back angleexists. According to the air vehicle provided by the invention, the wings adopt the double front and back wings, so that a sufficient area is ensured, and the requirements on a hangar and a taking-off and landing site are reduced; each front wing is the lower single wing, each main wing is the upper single wing, the wing taper ratio of each main wing to each front wing is 1 to 1, and no weepbackangle exists, so that the flying aerodynamic efficiency is improved; the air vehicle is improved in combination property, and has better flat light performance and vertical take-off and landing performance at the same time.

Description

technical field [0001] The invention relates to the technical field of aviation flight, in particular to an aircraft. Background technique [0002] The traditional types of small aircraft that realize vertical take-off and landing are mainly helicopters and multi-rotor aircraft. The traditional aircraft includes a fuselage body and wings arranged on the fuselage body. control device. [0003] Among them, the distributed propulsion system is an important part of the aircraft. Traditional vertical take-off and landing aircraft is difficult to balance between vertical take-off and landing performance and level flight performance. Improving one is generally at the expense of the other. [0004] Therefore, how to balance the performance of level flight and vertical take-off and landing, and obtain an aircraft design with high level flight performance and vertical take-off and landing performance simultaneously, is a technical problem to be solved urgently by those skilled in th...
