Embodiment Construction

[0037] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0038] Such as figure 1 As shown, the single-wing aircraft with rotor and fixed-wing flight modes includes a fuselage 6, an empennage 7, a wheel set 8, a control box 9 with a power supply that can receive remote control signals, and a fuel tank that is arranged on the fuselage 6. The power system 3, the rotating main shaft system 1, and the wing system 2 combined with the rotating main shaft system 1; the aircraft has its own electric drive system, which makes the wheel set 8 roll through a series of transmissions to drive the entire aircraft to slide on the ground, so that Drive to park or take-off position. The above-mentioned rotating spindle system 1 includes a brake mechanism 10 for braking the spindle 102, a spindle base 101 fixed on the fuselage 6, and a spindle 102 rotatably mounted on the spindle base 101 through a spindle bearing ass...

Abstract

The invention relates to a single-wing aircraft with both rotor and fixed-wing flight modes and a mode switching method in the field of aircraft technology. The controllable combination of jet flow through the jet holes at the wing end can realize the deceleration, speed-up and speed-up of wing rotation of the drone. and deceleration, automatically switch the rotor-vertical lift, fixed wing-high-speed cruise mode, reduce energy consumption during flight; when driving the wings to rotate, the high-pressure airflow formed by the turbojet engine flows through the cavity of the main shaft and passes to the wing end The air jet hole, the main shaft communicates with the air connection pipeline through the rotary joint, so that two of the air jet holes at the wing end arranged diagonally discharge high-speed airflow, forming a reverse torque to drive the wing to rotate around the main shaft; the wing rotation only applies The lifting force of the fuselage can realize the vertical take-off and landing function of the rotor; the main shaft is equipped with an incomplete gear positioning mechanism and a brake mechanism to realize the fast switching between the rotor and fixed wing modes and the precise positioning function and are independent of each other; when adjusting the angle of attack of the wing, the air supply pipe The road can be adaptively deformed.

Description

technical field [0001] The invention relates to the field of aircraft technology, in particular, an unmanned aircraft with switchable flight modes. Background technique [0002] The wing types of unmanned aerial vehicles can be roughly divided into fixed wings, rotary wings, flapping wings, and umbrella wings; unmanned aerial vehicles can also be divided into monoplane aircraft and compound wing aircraft according to the number of wings. At present, most common compound-wing aircraft are a combination of rotors and fixed wings. The rotors can not only realize the vertical take-off and landing function of the aircraft, but also realize the cruise function; most of the fixed wings realize the cruise function. Patent CN107719659A discloses a fixed-wing aircraft capable of vertical take-off and landing, which combines the advantages of vertical take-off and landing and hovering of multi-rotor aircraft with the advantages of fast cruise speed of fixed-wing aircraft; patent CN1080...
