Problems solved by technology

When the aircraft needs to brake for take-off and landing, the accurate speed signal is particularly critical, which directly affects the braking performance; during the taxiing process, due to insufficient pressure or burst tires of individual wheels, it may lead to deviation from the runway and cause safety hazards; while long-distance taxiing may Frequent use of the brakes will cause the temperature of the brake device to be too high. In severe cases, it may cause the aircraft brake device to catch fire

Embodiment Construction

[0037] In order to make the objects, technical solutions and advantages of the present invention clearer, the following will describe the embodiments of the present invention in detail with reference to the accompanying drawings. It should be noted that, the embodiments in the present application and the features in the embodiments may be arbitrarily combined with each other if there is no conflict.

[0038] In the existing patent CN105752053A "Aircraft Brake Cooling System and Method", compressed gas is used to cool the brake device. The compressed gas cylinder used in this method is suitable for small aircraft with a small number of wheels. The method has a long cooling time and high efficiency. Low. This method is different from the cooling method used in the following embodiments of the present invention. The embodiment of the present invention adopts the method of a brake cooling fan to rapidly cool the wheel, and it has been verified that the cooling time is short and t...

Abstract

The embodiment of the present invention discloses a multifunctional aircraft brake cooling control device, comprising: a brake cooling fan, a tire pressure sensor, a wheel speed sensor and a brake cooling motor; the central shaft hole of the wheel speed sensor passes through the long length of the brake cooling motor The shaft is fixed at one end of the brake cooling motor; the wheel speed sensor is used to monitor the speed of the aircraft tires; the central shaft hole of the tire pressure sensor passes through the long shaft of the brake cooling motor and is fixed at one end of the wheel speed sensor ; The tire pressure sensor is provided with a pressure sensor connected to the aircraft tire, which is used to rotate synchronously with the aircraft tire, so as to monitor the pressure of the aircraft tire; the brake cooling fan is installed at the end of the long shaft of the brake cooling motor to pass the brake The long shaft of the cooling motor is driven to rotate, and the airflow for cooling the aircraft tires is generated. The embodiment of the present invention realizes the integration of aircraft tire pressure detection, wheel speed detection and brake cooling and cooling functions.

Description

technical field [0001] The present application relates to, but is not limited to, the technical field of aircraft brake systems, and more particularly, to a multifunctional aircraft brake cooling control device. Background technique [0002] In the stages of take-off, landing, taxi braking, etc., factors such as wheel speed, tire pressure and braking temperature directly affect the reliability and safety of aircraft braking. When the aircraft needs to be braked for take-off and landing, the accurate speed signal is particularly critical, which directly affects the braking performance; during the taxiing process of the aircraft, due to insufficient tire pressure or tire blowout of individual wheels, it may lead to deviation from the runway and cause safety hazards; and long-distance taxiing may Frequent use of the brakes will cause the brakes to overheat, and in severe cases may cause the aircraft brakes to catch fire. Therefore, it is very necessary for aircraft tire pressu...
