Abstract

The invention discloses an electromagnetic arresting device for deck landing or landing of an aircraft and relates to an electromagnetic arresting system. The problems that an existing landing assisting and arresting system is large in weight and size, complicated in structure, low in reliability and the like are solved. The device comprises two rotary electromagnetic arresters of the same structure, and an arresting cable. Each rotary electromagnetic arrester comprises a rotary motor, a rotary eddy current retarder brake, an arresting cable drum and a motor driven controller, wherein the rotary motor, the rotary eddy current retarder brake and the arresting cable drum share one rotary shaft. The two rotary electromagnetic arresters are arranged symmetric with an aircraft landing runway as the center, and the two ends of the arresting cable are wound on the two arresting cable drums correspondingly. The electromagnetic arresting device adapts to deck landing or landing of a carrier aircraft.

Description

technical field [0001] The invention relates to an electromagnetic arresting system, which is suitable for the landing or landing of aircraft carriers. Background technique [0002] At present, the carrier-based aircraft landing-assisted arresting system on the aircraft carrier mainly uses arresting cables. Due to the very high flight speed, when the carrier-based aircraft is landing on the ship, the deck length of the aircraft carrier is far from meeting the landing glide distance, so the resistance of the arresting cable must be used to make it land smoothly. [0003] The traditional arresting cable system uses a hydraulic arresting device, which has the disadvantages of many moving parts, heavy system weight, large instantaneous impact force, and low reliability. In addition, in order to prevent the arresting load from exceeding the body strength or the braking force of the hydraulic arresting device during landing, the hydraulic arresting device has strict requirements ...
