double wing aircraft

Abstract

The invention discloses a double-layer-wing aircraft relating to the technical field of aviation. The double-layer-wing aircraft comprises an upper wing, a lower wing, a left vertical wing, a right vertical wing, a rear vertical wing, a power device, an undercarriage and an aircraft body. The upper wing is composed of a fixing part positioned at the front and an elevator. The rear vertical wing is composed of a fixing part close to the front and a rudder. The left section of the lower wing and the right section of the lower wing are respectively, symmetrically and fixedly connected to the left side and the right side of the front lower part of the aircraft body, and a left aileron and a right aileron are arranged at wing tips of the left section of the lower wing and the right section of the lower wing. The left vertical wing and the right vertical wing are respectively symmetrically arranged at the left wing tip part and the right wing tip part of the overlapped part of the upper wing and the lower wing in a vertical direction. The aircraft can be controlled to laterally move by controlling the deflection of the left vertical wing and the right vertical wing. A left vane grid and a right vane grid for horizontally guiding a flow are respectively additionally arranged at rear parts of a left propeller and a right propeller. The aircraft is compact in structure, high in efficiency, and capable of performing high-incidence flight, and facilitates the realization of super-short take-off and landing and ultra-low speed flight.

Description

technical field [0001] A double-wing aircraft belongs to the technical field of aviation, and in particular relates to a double-wing aircraft. Background technique [0002] Traditional biplanes are difficult to achieve short-distance takeoff and landing, and have a long tail, which takes up a lot of space; the efficiency of the wings is low, and it is easy to stall. The critical stall angle of attack is small and the stability is poor. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned deficiency of traditional biplane, invent a kind of double-wing aircraft that does not have long tail and can take off and land in a short distance. [0004] A double-wing aircraft comprises an upper wing, a lower wing, a left vertical wing, a right vertical wing, a rear vertical wing, a power unit, a landing gear and a fuselage. The fuselage is equipped with a control system and airborne equipment. The landing gear adopts the front t...
