Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0030] Such as Figures 1 to 2 As shown, a permanent magnet linear motor type unmanned aerial vehicle electromagnetic catapult of the present invention includes: an ejection frame 1, an unmanned aerial vehicle supporting ejection platform 2, a control system 3, a braking system 4, an electromagnetic protection device 5, a power supply System 6 etc. The ejection frame 1 can be directly installed and fixed on a small-tonnage truck 7 or be connected with a trailer tow to realize fast transportation. The ejection frame 1 is composed of 5# square tube profiles and plates welded and spliced, and has a simple and firm structure. The front part of the ejection frame is made of 3# angle steel to form a support rod, so that the entire ejector forms a certain ejection angle with the horizontal plane. Eject Rack1. First, it plays the role of supporting...

Abstract

The invention provides a permanent magnet linear motor type electromagnetic catapult for an unmanned aerial vehicle. The permanent magnet linear motor type electromagnetic catapult comprises a catapulting rack, an unmanned aerial vehicle supporting and catapulting platform, a power supply system, a brake system and a control system. The permanent magnet linear motor type electromagnetic catapult is characterized in that the catapulting rack can be carried on transport equipment and is provided with linear slide rails, the unmanned aerial vehicle supporting and catapulting platform is supported on the linear slide rails of the catapulting rack through the two sides of the unmanned aerial vehicle supporting and catapulting platform, the catapulting rack is provided with the brake system, the unmanned aerial vehicle is carried on the unmanned aerial vehicle supporting and catapulting platform which can be driven by a catapulting motor to accelerate along the linear slide rails, the catapulting motor is a permanent magnetic linear motor, and when the unmanned aerial vehicle reaches the speed needed for taking-off, the unmanned aerial vehicle supporting and catapulting platform is braked under the damping effect of the brake system, and the unmanned aerial vehicle flies out inertially. The permanent magnet linear motor type electromagnetic catapult overcomes the problems that in the prior art, an unmanned aerial vehicle is poor in maneuverability, low in reliability, poor in concealment and low in efficiency during catapulting.

Description

technical field [0001] The invention mainly relates to the field of unmanned aerial vehicle ejection and take-off, in particular to an electromagnetic ejector adopting a moving-coil permanent magnet linear motor. Background technique [0002] With the development of high technology and the continuous revolution of information technology, the form of modern warfare is also changing. Unmanned combat has become the development trend of modern warfare, and drones have become an indispensable weapon and play an important role. With the development of unmanned combat situation, the role of unmanned aerial vehicles (UAVs) has become increasingly prominent on the modern battlefield, and the research on various launch and take-off technologies of fixed-wing UAVs has also highlighted its urgency. [0003] At present, most large and medium-sized UAVs use fixed-site run-up take-off, pyrotechnic boost, and gas-liquid catapult to take off; Due to the constraints of pyrotechnics, a large ...
