Fixed-wing unmanned airplane vertical takeoff method

Abstract

The invention provides a fixed-wing unmanned airplane release mechanism. The fixed-wing unmanned airplane release mechanism includes a steering machine, a steering wheel, a transmission rod, and a mounting block, wherein the steering machine comprises an output shaft; one end of the steering wheel is fixedly connected to the output shaft; a latching rod is hinged to one end of a connecting rod andthe other end of the steering wheel; one end of the latching rod is hinged to the other end of the connecting rod; the mounting block is fixedly mounted on the steering machine, a clamping groove isformed in the middle of the mounting block, a through hole is formed in the mounting block in the transverse direction, and the other end of the latching rod penetrates the through hole and extends into the clamping groove; the inner side wall, away from the steering wheel, of the clamping groove abuts against the other end of the latching rod; and the steering machine can drive the latching rod to reciprocate in the through hole. The unmanned airplane release mechanism is stable in flight and long in duration of flight.

Description

technical field

[0001] The invention relates to the technical field of aircraft, in particular to a vertical take-off method for a fixed-wing unmanned aerial vehicle. Background technique

[0002] UAVs refer to unmanned aircraft controlled by wireless remote control equipment and their own control devices, such as unmanned helicopters, fixed-wing UAVs, and unmanned paragliders. In the past ten years, drones have been widely used in aerial photography, power inspection, environmental monitoring, forest fire prevention, disaster inspection, anti-terrorism lifesaving, military reconnaissance, battlefield assessment and other fields.

[0003] At present, the common fixed-wing UAV wings that can take off and land vertically are composite flying-wing UAVs that combine multi-axis and fixed wings. However, this type of multi-rotor will no longer work after take-off. The UAV is equivalent to flying with redundant multi-rotors, which seriously affects the endurance time and flight at...

The inner wall of the slot 401 away from the steering wheel 102 is against the other end of the latch rod 30, and the steering gear 101 can drive the latch rod. 30 reciprocates in...

Embodiment 2

[0051] Such as figure 2 As shown, the present embodiment provides a fixed-wing unmanned aerial vehicle, including the unmanned aerial vehicle release mechanism of embodiment 1; The other end of the connecting rod 60 is provided with a hanging ring 70;

[0052] Both the multicopter and the fixed-wing aircraft 50 structures are prior art.

[0053] The multi-axis aircraft and the fixed-wing aircraft 50 are connected through the unmanned aerial vehicle release mechanism. The fixed-wing aircraft 50 is hung on the latch rod 30 in the card slot 401 through the hanging ring 70 provided on the connecting rod 60 , and controlled by the steering gear 101. The rotation of the multi-axis aircraft and the fixed-wing aircraft 50 can be flexibly and quickly realized the switching between the fixation and release of the multi-axis aircraft and the fixed-wing aircraft 50, and the separation of the multi-axis aircraft and the fixed-wing aircraft 50 can be realized during flight, thereby avoidi...
