Vertical take-off and landing fixed-wing unmanned aerial vehicle

Abstract

The invention provides a vertical take-off and landing fixed-wing unmanned aerial vehicle, which belongs to the technical field of aircrafts. The purpose is to solving problems that the take-off and landing condition of a fixed-wing aircraft is harsh, the loitering speed of a rotor craft is low and the endurance of the rotor craft is short in the prior art are solved. The vertical take-off and landing fixed-wing unmanned aerial vehicle comprises a fixed-wing structure system, a fixed-wing power system, a rotor structure and power system, a rotor structure supporting piece as well as a flight control system and an avionic system, wherein the fixed-wing power system comprises a single cylinder two-stroke engine and a propeller A, which are fixed at the tail end of an aerial vehicle body; a power output end of the engine is connected with the propeller A; the rotor structure and power system is arranged on the fixed-wing structure system; the rotor structure and power system comprises a motor, an electronic speed controller and propellers B; the motor is electrically connected with the electronic speed controller; an output end of the motor is connected with the propellers B; four propellers B are respectively arranged on the upper end surfaces of two supporting rods of the fixed-wing structure system; the propeller A is perpendicular to the propellers B; the rotor structure supporting piece is fixed at the upper end of a wing of the fixed-wing structure system and used for mounting a rotor power system; and the flight control system and the avionic system are used for controlling the flight path and posture of the unmanned aerial vehicle.

Description

technical field [0001] The invention belongs to the technical field of aircraft, and in particular relates to a vertical take-off and landing fixed-wing unmanned aircraft. Background technique [0002] Traditional unmanned aerial vehicles can be divided into two types: fixed-wing aircraft and rotary-wing aircraft. Fixed-wing aircraft fly fast, and have a long range and flight time. According to the size of the model, it can take off by hand throwing, catapulting or sliding, and land by opening the parachute, hitting the net or sliding, but the general take-off and landing conditions demanding. The flying speed of the rotorcraft is slow, but because of its regular fuselage structure and simple flight principle, it can use the rotor to take off and land vertically, and hover in the air with a stable attitude. Both fixed-wing aircraft and rotary-wing aircraft have their own shortcomings and cannot fully meet the needs. Contents of the invention [0003] The purpose of the ...
