Integral construction of hydraulic-electric composite brake aircraft carrier arrester and arrester system

Abstract

The invention provides an integrated hydraulic-electric composite braking aircraft carrier arrester, which includes a hub-type eddy-current auxiliary brake with a distributed arrangement of multiple sets of excitation coils. The hub-type eddy-current auxiliary brake includes a stator, a side cover and a rotor. The stator and the rotor are the same The shaft is set, the stator is located outside the rotor, the side covers are sealed at both ends of the stator and the rotor, and there are interpenetrating coolant channels between the rotor and the side covers, and between the rotor and the stator, and the coolant channels form a hydraulic auxiliary brake The present invention overcomes the deficiencies of existing arresting devices, provides a kind of high power density, simple structure, small size, low cost, convenient control, fast response speed, torque-adjustable novel hydraulic-electric composite structure aircraft carrier arrester and the application of the arrester The blocking system of the machine.

Description

technical field [0001] The invention belongs to the field of non-contact auxiliary braking, and in particular relates to an aircraft carrier arrester with an integrated hydraulic-electric composite brake and an arrester system using the arrester. Background technique [0002] The flight speed of modern fixed-wing carrier-based aircraft is about 200-300km / h. In order to make it safely land on the deck of an aircraft carrier with limited length, an aircraft carrier blocking device must be installed. The device also needs to meet the safe landing of carrier-based aircraft of different tonnages; most aircraft carriers in the prior art use hydraulic buffer arresting devices, which are complex in structure, expensive, and technically difficult; carrier-based aircraft deviate from the normal track, As a result, the force on both ends of the hooked arresting cable is unequal, and it is necessary to correct the deviation of the carrier-based aircraft by adjusting the output braking p...

The existing liquid-cooled eddy current retarder with a salient pole structure, the patent application number 201210061975.6 compensates for the lack of braking power by increasing the diameter. This type of brake only works on the outer ring, and the inner ring space is wasted

Among the electromagnetic auxiliary brakes, the response time of the eddy current retarder distributed by multiple excitation coils (such as the traditional air-cooled eddy current retarder) is faster than that of the eddy current retarder distributed by the single excitation coil (such as the liquid-cooled retarder with salient pole structure). type electric eddy current retarder); for the hydraulic retarder, the performance is superior at high speed, but the braking power at low speed is low, the response time is long, and it is difficult to adjust the torque in time
