Rotating-centrifugal acceleration takeoff device for light and small unmanned aerial vehicle

Abstract

The invention discloses a rotating-centrifugal acceleration takeoff device for a light and small unmanned aerial vehicle. The rotating-centrifugal acceleration takeoff device for the light and small unmanned aerial vehicle comprises a power mechanism, a cantilever structure, a brake device and a releasing device. one end of the cantilever mechanism is connected with the output end of the power mechanism and the other end of the cantilever mechanism is connected with the releasing device, and the unmanned aerial vehicle is provided with a connecting piece the lower part for being fixed on the releasing device; the power mechanism comprises a box-type base, a motor, a power supply, a clutch and a controller, the motor is vertically arranged in the box-type base, an output shaft of the motoris connected with the clutch, and the clutch is connected with a rotating shaft, and the rotating shaft is a hollow first straight pipe. By accelerating the rotation of a second straight tube, then, when the linear speed of the outer end of the second straight pipe reaches or exceeds the minimum flight speed of the unmanned aerial vehicle, the unmanned aerial vehicle is released for takeoff, the accelerated linear motion of the unmanned aerial vehicle is converted into rotating motion, the rotating-centrifugal acceleration takeoff device has low requirements on the takeoff site and can be usedas the takeoff device of the light and small rotating in most cases, and is convenient and flexible.

Description

technical field [0001] The invention relates to the technical field of take-off devices for unmanned aerial vehicles, in particular to a rotary centrifugal acceleration take-off device for light and small unmanned aerial vehicles. Background technique [0002] In recent years, drones have developed rapidly. UAVs can be divided into two categories: fixed-wing UAVs and rotary-wing UAVs. Rotary-wing UAVs can take off and land vertically. Good, less load and other shortcomings. The fixed-wing UAV has a relatively long battery life and a relatively large load, and its flight control is easier than that of a rotary-wing UAV. However, a fixed-wing UAV needs a certain speed to take off, and has higher requirements for the take-off site. [0003] The take-off methods of existing fixed-wing UAVs are mostly taxi take-off, vehicle take-off, rocket-assisted take-off, etc. These methods either require a long straight runway or a relatively open launch site, which is useful to use.

Problems solved by technology

UAVs can be divided into two categories: fixed-wing UAVs and rotary-wing UAVs. Rotary-wing UAVs can take off and land vertically. They have lower requirements on the take-off site and are flexible to use. However, they generally have a long battery life and unstable flight stability. Good, less load and other disadvantages

The fixed-wing UAV has a relatively long battery life and a relatively large load. The flight control is easier than that of the rotary-wing UAV, but the fixed-wing UAV needs a certain speed to take off, and has higher requirements for the take-off site.

[0003] The take-off methods of existing fixed-wing UAVs are mostly taxi take-off, vehicle-mounted take-off, rocket-assisted take-off, etc. These methods either require a long straight runway or a relatively open launch site. many inconveniences
