Fixed-wing aircraft capable of vertically taking off and landing

Abstract

The invention discloses a fixed-wing aircraft capable of vertically taking off and landing. The fixed-wing aircraft comprises a wing, a power system, a control system and an aircraft body connecting and supporting mechanism, wherein the wing uses high lift-to-drag ratio design, and is used for providing lift force during horizontal flight, the power system comprises an even number of screw propellers having a total number of at least 4 and corresponding motors, the screw propellers are symmetrically fixed to both sides of the wing, the control system controls the normal flight, the vertical taking-off and landing, and the flight state switching of the aircraft, and the body connecting and supporting mechanism comprises aircraft arms for connecting the wing and the power system and landinggears for supporting the whole aircraft. According to the technical scheme of the embodiments of the present invention, the aircraft uses the taking-off mode similar to the multi-rotor taking-off mode, the whole aircraft is converted into the horizontal flight state, and the wing supplies the lift life during the horizontal flight so as to prolong the continuous flight time of the aircraft; and excluding the screw propeller, the aircraft does not have other moving mechanism, such that the fixed-wing aircraft has characteristics of simple structure, high reliability and energy saving.

Description

technical field [0001] This application generally relates to the field of aviation aircraft technology. In particular, it relates to a fixed-wing aircraft that can take off and land vertically. Background technique [0002] Fixed-wing aircraft have the characteristics of long flight time and long range, but take-off and landing generally require long-distance taxiing runways, so there are relatively large restrictions on the use environment. Some small fixed-wing aircraft use catapult takeoff or hand-throw takeoff, and parachute-assisted landing. Although they do not need a special runway, they need special catapults or professionally trained operators when taking off. Although parachutes can slow down The impact of the aircraft landing still has some damage to the aircraft, which is obviously not an ideal way. [0003] Vertical take-off and landing fixed-wing aircraft can solve the above problems. Existing vertical take-off and landing fixed-wing aircraft mainly include ...

AI Technical Summary

Problems solved by technology

[0004] Among the above three methods, the tailstock vertical take-off and landing aircraft is difficult to control due to the low speed and limited effectiveness of the rudder surface during the take-off and landing phases.

Both the first and third methods require additional mechanisms, which increase the weight of the aircraft, reduce reliability, and shorten the flight range of the aircraft
