Braking cooling system of main airplane wheel of multi-wheel-train airplane

Abstract

The invention discloses a braking cooling system of a main airplane wheel of a multi-wheel-train airplane. The braking cooling system comprises a plurality of braking cooling assemblies and a temperature monitoring control box. Temperature sensors in the braking cooling assemblies are inserted into temperature sensor installation holes in a braking shell correspondingly. The signal input ends of the temperature sensors are connected to a temperature socket of the temperature monitoring control box together, and the power source input ends of braking cooling motors communicate with a motor socket of a temperature detection unit together. An output bus of the temperature monitoring control box communicates with an airplane cockpit instrument panel, and a power source of the airplane serves as a power source of the temperature monitoring control box. The two ends of a cooling switch are connected with the input end of the temperature monitoring control box and the power source of the airplane correspondingly. By the adoption of the braking cooling system, cooling can be conducted in advance in the airplane taxiing process, the dispatching frequency of the airplane is increased, the aging rates of a braking device and parts of the braking device are reduced, the whole service life of the braking device is prolonged, and the economical index is improved.

Description

technical field [0001] The invention relates to the field of aircraft brake cooling systems, in particular to a multi-wheel system aircraft main engine wheel brake cooling system. Background technique [0002] When the aircraft performs various tasks, there is a need for long-distance and long-term taxiing such as waiting for dispatch and transition. During continuous taxiing, the temperature of the brake device will be too high due to frequent use of the brakes, and the temperature exceeding the take-off limit will affect the aircraft's re-scheduling. At present, the wheel cooling methods mainly include natural cooling, air-conditioning vehicle blowing and nitrogen cylinders. The natural cooling time is too long to meet the time requirements for dispatching again; air-conditioning vehicles can only be used to blow air or nitrogen cylinders to cool down after shutdown, and the operation is very inconvenient. The blowing efficiency is low and the cooling time is long, and th...
