Embodiment Construction

[0048] The present invention will be further described below in conjunction with specific embodiment and accompanying drawing, set forth more details in the following description so as to fully understand the present invention, but the present invention can obviously be implemented in many other ways different from this description, Those skilled in the art can make similar promotions and deductions based on actual application situations without violating the connotation of the present invention, so the content of this specific embodiment should not limit the protection scope of the present invention.

[0049] The principle of the infrared temperature measurement sensor is as follows: objects with a temperature above absolute zero will radiate infrared rays due to their own molecular motion. After the power signal radiated by the object is converted into an electrical signal by the infrared detector, the processor can simulate the spatial distribution of the surface temperature...

Abstract

The invention relates to an airplane brake cooling system and method. The airplane brake cooling system comprises an infrared temperature measurement sensor, a brake temperature monitoring unit, and a brake cooling unit, wherein the infrared temperature measurement sensor is mounted on an airplane undercarriage and is used for measuring the temperature of an airplane brake disc; the brake temperature monitoring unit is connected to the infrared temperature measurement sensor and is used for monitoring temperature signals measured by the infrared temperature measurement sensor; the brake cooling unit is mounted on the undercarriage and is used for cooling down the airplane brake disc. The airplane brake cooling system and method have the following benefits: the temperature of the airplane brake disc can be conveniently measured, and the airplane brake disc can be effectively cooled down.

Description

technical field [0001] The invention relates to an aircraft brake cooling system and method, and belongs to the technical field of aircraft brake systems. Background technique [0002] At present, the aircraft brake temperature monitoring system generally consists of the following three parts: a) temperature sensor part: K-type thermocouple used to measure the temperature of the brake disc; b) brake temperature compensation module BTCM used to compensate the cold junction of the thermocouple; c ) The brake temperature monitoring unit receives and processes the signal from the brake temperature sensor. [0003] At present, the active cooling measures for aircraft brakes are mainly to use fans to blow air for cooling, and they are not linked with the aircraft brake temperature monitoring system to achieve automatic cooling control. [0004] The traditional thermocouple is installed on the inner side of the brake disc, close to the wheel shaft. The disadvantage of this method ...
