Aircraft hydraulic trainer brake system

Abstract

The invention belongs to the technical field of aircraft braking system design, and especially relates to a hydraulic training braking system for aircraft. The hydraulic training braking system for aircraft includes a braking distribution valve (1), a braking switch valve (2), an always-open the two-position two-way electromagnetic valve (3), an always-closed two-position two-way electromagnetic valve (4), a hydraulic power source (5), an accumulator (6), a hydraulic oil tank (7), a braking sensor (8), a one-way valve (9), a braking airplane wheel (10), a normal emergency braking switch valve (11), a braking distribution valves (12) and a braking sensor (13). After the installation of the training braking system, the aircraft can adapt to a variety of terrains and environment for braking, so as to expands the application range of the aircraft in the training condition and improve the safety of aircraft braking on the ground.

Description

technical field [0001] The invention belongs to the technical field of aircraft brake system design, in particular to an aircraft hydraulic trainer brake system. Background technique [0002] Domestic and foreign existing training aircraft, there is no record of the aircraft hydraulic trainer overriding the brake system that the trainer can completely remove or restore the brake authority of the pilot at any time. At present, conventional trainer-type aircraft instructors can only brake synchronously with students or give priority to braking, but cannot fully control the brake authority of students at any time. Therefore, when an emergency occurs during the taxiing process and the student's brake authority needs to be released immediately, the brake action that the student has already performed cannot be quickly released, or the brake is stuck and stuck, resulting in unpredictable deflection, overturning and other forms of the aircraft. Danger. In view of the above-mention...

AI Technical Summary

Problems solved by technology

At present, the conventional trainer-type aircraft trainer can only brake synchronously with the trainee or give priority to the brake, but cannot fully control the brake authority of the trainee at any time

Therefore, when an emergency occurs during the taxiing process and the student's brake authority needs to be released immediately, the brake action that the student has already performed cannot be quickly released, or the brake is stuck and stuck, resulting in unpredictable deflection, overturning and other forms of the aircraft. Danger

In view of the above-mentioned shortcomings of the existing aircraft bilateral braking system, a technology is needed to change the situation that the flight instructor can only brake synchronously with the student or give priority to braking, but cannot fully control the braking authority of the student at any time. The present invention is based on the above reasons. The principle design of the hydraulic system and the combination of various hydraulic components and hydraulic mechanisms solve the problem that the aircraft instructor can only brake synchronously with the students or give priority to braking, but cannot fully control the students' braking authority at any time, and improves the ground taxiing of the aircraft. security
