Fixed-wing air vehicle with plurality of rotary wings

Abstract

The invention discloses a fixed-wing air vehicle with a plurality of rotary wings, and belongs to the field of air vehicles, aiming at solving the problems that an existing air vehicle is limited by a taking-off and landing field and a horizontal flight speed is slow. The fixed-wing air vehicle comprises a fuselage, two wings, a first propulsion unit and a second propulsion unit; the two wings are movably fixed at two sides of the fuselage respectively; the two wings are arranged in a V shape and openings of the two wings are arranged toward a tail part of the fuselage; the first propulsion unit is used for generating a horizontal pulling force or a horizontal pushing force on the air vehicle; the second propulsion unit is coupled onto the fuselage or the wings; the second propulsion unit is used for generating a vertical lifting force on the air vehicle.

Description

technical field [0001] The invention relates to the field of aircraft, in particular to a fixed-wing aircraft with multi-rotors. Background technique [0002] Common aircraft in the aviation field include fixed-wing and multi-rotor. Among them, the fixed-wing is driven by the engine, which generates horizontal thrust parallel to the axis of the fuselage, so that the fixed-wing can fly at high speed in the air. However, since the engine cannot produce lift perpendicular to the axis of the fuselage, the fixed wing can only obtain lift through the relative movement between the fixed wing and the air, so as to overcome the gravity of the fixed wing, the magnitude of the lift and the relative movement between the fixed wing and the air There is a positive correlation between the speed and the greater the relative speed, the greater the lift obtained by the fixed wing. However, there are two disadvantages in the fixed wing of the prior art: the first, a long runway is needed to m...
