Aircraft airborne brake air cooling control system based on temperature and design method thereof

Abstract

The invention provides an aircraft airborne brake air cooling control system based on a temperature and a design method thereof. A relay power supply communicates with one end of a fan control circuitprotection automatic switch; the other end of the fan control circuit protection automatic switch communicates with an input end of a right brake aircraft wheel landing switch; an output end of the right brake aircraft wheel landing switch communicates with an input end of a left brake aircraft wheel landing switch; and an output end of the left brake aircraft wheel landing switch communicates with an input end of a brake fan switch. When an input end a of the brake fan switch communicates with a turn-off end c, the brake fan switch is turned off; and when the input end a of the brake fan switch communicates with an input end b of a relay working contact, the brake fan switch communicates with a working contact of the replay power supply. According to the aircraft airborne brake air cooling control system based on the temperature and the design method thereof, when the temperature of a brake aircraft wheel reaches a condition of high temperature, the brake aircraft wheel can be reliably cooled in time after an aircraft lands on the ground; and therefore, the taking-off and landing period of the aircraft is shortened from 60-90 min to 30 min so that the taking-off and landing timeof the aircraft is shortened, and the taking-off and landing frequency of the aircraft is increased. Meanwhile, the energy is saved, and the labor intensity of the ground crew is reduced.

Description

technical field [0001] The invention relates to an air-cooling system for airborne brakes of an aircraft, in particular to an air-cooled control system for airborne brakes of an aircraft and a design method thereof. Background technique [0002] Modern aircraft have higher take-off speeds, heavier landing weights, and higher braking speeds, which increase the braking energy of the aircraft and greatly increase the temperature of the brakes, wheels, and brakes. To ensure that the aircraft is dispatched quickly, forced cooling of the brakes is necessary. Modern aircraft brake wheel cooling device has become a necessary device for aircraft brake wheel and brake system design. [0003] Most of the second-generation and third-generation aircraft in active service use metal-based powder alloy brake materials. In order to ensure the rapid dispatch of the aircraft, forced water cooling or air cooling on the ground is adopted to ensure the rapid dispatch of the aircraft. C / C and C / S...

[0008] But the publication number is CN106005379A, and this invention is to adopt the cooling plate and the air inlet joint to import the cooling gas into the ventilation hole of the aircraft brake wheel to implement the cooling effect, and punching holes on the aircraft brake wheel will reduce the structural strength of the aircraft brake wheel, and at the same time Using an external air source to cool the aircraft brake wheel increases the labor intensity of the staff and delays the cooling time of the aircraft brake wheel

The invention did not clearly state the specific reasonable value of the temperature warning value setting and the specific requirements for the automatic start and stop of the air cooling system
