Embodiment Construction

[0014] like figure 1 Shown, a kind of unmanned aerial vehicle electromagnetic catapult, comprises landing gear assembly 1, draw bar 2, driving device and reclining device 5, and described driving device is made up of linear motor 3 and ejection shuttle 4, and described ejection shuttle 4 Hinged with the end of the drawbar 2.

[0015] The mover slider of the linear motor 3 drags the aircraft through the ejection shuttle 4 under the action of electromagnetic force to make it reach the take-off speed.

[0016] The ejection take-off of UAV mainly includes three stages: the tensioning stage, the ejection and sliding stage, and the thrust-off stage.

[0017] like figure 2 As shown, a magnetic device 41 with strong suction is designed inside the shooting shuttle 4, and a magnetic device 42 is arranged at the position where the draw bar 2 contacts the shooting shuttle 4, and a suction force is generated during the moving process of the shooting shuttle 4 to slow down the vibration,...

Abstract

The invention provides an electromagnetic catapult for an unmanned aerial vehicle. The electromagnetic catapult for the unmanned aerial vehicle comprises a landing gear assembly, a traction rod, a driving device and a leaning device; the driving device consists of a linear motor and a catapult shuttle; the catapult shuttle is hinged with the tail end of the traction rod; a magnetic device with strong suction power is arranged in the catapult shuttle; and a magnetic device is arranged in a position, in contact with the catapult shuttle, of the traction rod. Suction force is generated in the moving process of the catapult shuttle to relieve the vibration to be beneficial for the catapult of the unmanned aerial vehicle. The electromagnetic catapult for the unmanned aerial vehicle has the advantages that the vibration amplitudes of the catapult shuttle and the traction rod in the catapult process can be reduced, adverse effects brought by vibration can be weakened and the electromagnetic catapult is beneficial for the catapult of the unmanned aerial vehicle.

Description

technical field [0001] The invention relates to a launching device for an unmanned aircraft, in particular to an electromagnetic catapult for an unmanned aircraft. Background technique [0002] When the UAV takes off on the ground, it mainly adopts two methods: take-off on the launch vehicle and catapult take-off. The take-off on the launch vehicle is to install the UAV on the launch vehicle. Under the thrust of the engine on the aircraft, the combination of the UAV and the launch vehicle will slide along the ordinary slideway. man-machine. This launch mode has complex structure, high manufacturing cost and difficult maintenance. Catapult take-off is to install the UAV on the ejection frame. When the UAV ejects and takes off, the aircraft restraint lever and the ejection lever must be connected to the catapult restraint device and the catapult dragging shuttle respectively, and the restraint lever is pulled off by constant force. The bolt is hinged with the upper and lowe...
