Four-ducted propeller powered fixed-wing unmanned aerial vehicle capable of achieving vertical take-off and landing

Abstract

The invention discloses a four-ducted propeller powered fixed-wing unmanned aerial vehicle capable of achieving vertical take-off and landing, and belongs to the field of unmanned aerial vehicles. Thefour-ducted propeller powered fixed-wing unmanned aerial vehicle capable of achieving vertical take-off and landing comprises a structural unit, power units and a flight control and avionic unit, wherein the structural unit comprises a fuselage, wings, control planes and tail supporting rods; the fuselage is positioned at a central position of the whole unmanned aerial vehicle; four wings are fixed to the fuselage; the adjacent wings of the four wings form included angles of 90 degrees; the power units are arranged on the tips of the four wings; the control planes are arranged on the four wings; the tail supporting rod is arranged on each wing; each power unit comprises four sets of ducted propellers; a set of ducted propeller is arranged on each wing; the flight control and avionic unitis mounted inside the inner cavity of the fuselage. The unmanned aerial vehicle system has relatively low overall power redundancy and relatively high using efficiency, and can achieve vertical take-off and landing, fixed-point hover in the air and efficient cruise and level flight.

Description

technical field [0001] The invention belongs to the general technical field of unmanned aerial vehicles, and more specifically relates to a fixed-wing unmanned aerial vehicle capable of vertical take-off and landing in a four-duct propeller power mode. Background technique [0002] Traditional unmanned aerial vehicles can be divided into two types: fixed-wing and rotary-wing aircraft. When the fixed-wing aircraft is flying, the lift is provided by the wings, and the flight time and range are relatively large. According to the difference in weight and size, the fixed-wing aircraft can choose to take off by hand throwing, ejection, taxiing, etc., and land and recover by hitting the net, parachuting, and taxiing. [0003] Generally speaking, the take-off and landing conditions of fixed-wing aircraft are relatively harsh. Rolling take-off or landing requires a relatively flat runway. Catapult take-off requires a special ejection device. navigation control system, etc. In addi...

AI Technical Summary

Problems solved by technology

The tilting device of the tilting-rotor aircraft is technically difficult and the mechanism is complicated, so it is difficult to guarantee reliability, and the tilting mechanism itself has a considerable part of the weight, which also affects the cruise efficiency to a certain extent
