Abstract

The invention relates to a quick release circuit for redundancy control. The quick release circuit for redundancy control comprises a power supply and a first quick release unit. The first quick release unit comprises a pure resistor, a diode and a quick release component. One end of the resistor is connected with the anode of the power supply while the other end of the resistor is connected with the cathode of the diode. The anode of the diode is connected with one end of the quick release component, the other end of the quick release component is connected with the cathode of the power supply, and a coil of an electromagnetic valve is connected to both ends of the power supply. According to the quick release circuit for redundancy control provided by the invention, the closing response speed of the electromagnetic valve is improved, the closing response time of the electromagnetic valve is shortened, and the design difficulty of the electromagnetic valve is reduced by further arranging the quick release circuit in a control loop of the electromagnetic valve.

Description

technical field [0001] The invention belongs to the technical field of aerospace engine control, and mainly relates to an aerospace engine solenoid valve control system, in particular to a redundant control solenoid valve rapid release circuit. Background technique [0002] During the flight of the aerospace vehicle, it is necessary to control and adjust the attitude of the aircraft through the rapid operation of the engine solenoid valve. The solenoid valve has high working pressure, large flow rate and fast response speed. The general method is to adopt a special structure in the design of the solenoid valve coil, the product process is complicated, the development is difficult and the cost is high. Contents of the invention [0003] In order to solve the technical problems of complex process, difficult research and development, and high cost in the prior art, the present invention provides a redundant control quick release circuit, which can improve the closing respons...
