Arresting Hook Retractable Control System for Shipborne Aircraft

Abstract

The invention provides a carrier-based aircraft arresting hook collecting and releasing control system which comprises a control valve, a collecting and releasing actuating cylinder, a collecting position lock actuating cylinder and a bypass valve. An oil inlet port of the bypass valve is connected with a pressure supply pipeline, and an oil return port of the bypass valve is connected with an oil return pipeline. One working port of the bypass valve is communicated with an oil inlet port of the control valve through a hydraulic pipeline, and the other work port of the bypass valve is communicated with a working port of a connecting collecting pipeline of the control valve through a hydraulic pipeline. An oil return port of the control valve is communicated with the oil return pipeline, a working port of the connecting collecting pipeline of the control valve is communicated with one cavity of the collecting and releasing actuating cylinder and one cavity of the collecting position lock actuating cylinder through hydraulic pipelines. A working port of a connecting releasing pipeline of the control valve is connected the other cavity of the collecting position lock actuating cylinder through a hydraulic pipeline. The carrier-based aircraft arresting hook collecting and releasing control system has the functions of normally collecting and releasing an arresting hook, when the arresting hook cannot be normally released, the collecting pipeline can be communicated with the return oil of the system by operating the bypass valve, it is ensured that the arresting hook is urgently put down, and the reliability of collecting and releasing of the carrier-based aircraft arresting hook is ensured.

Description

technical field [0001] The present disclosure relates to a shipboard aircraft arresting hook retraction control technology, in particular to a shipboard aircraft arresting hook retraction control system. Background technique [0002] During the landing process of carrier-based aircraft, due to the limitation of the size of the ship deck space, the way of arresting the aircraft is usually stopped by arresting hooks. Once the arresting hook cannot be put down, the aircraft will not be able to land on the ship. Therefore, the reliability of the arresting hook retraction control system on the carrier-based aircraft is very important. Under normal conditions, the arresting hook is equipped with a normal retractable system and an emergency release system. When the normal retractable system breaks down and the arresting hook cannot be put down, the arresting hook must be put down in an emergency release mode. [0003] However, there is such a situation that when the arresting ho...

Problems solved by technology

[0003] However, there is such a situation that when the arresting hook control valve is faulty and is in the retracted state, the arresting hook actuator is retracted due to the action of the oil circuit, so that the emergency release system cannot work normally and the arresting hook is put down in an emergency

In this way, the emergency release system of the arresting hook will not be able to play its role in emergency release, and it will also reduce the reliability of the release of the arresting hook.
