Redundancy control switch of flight control system

Abstract

The invention belongs to flight control technology and relates to improvement on the redundancy control switch of a flight control system. The system comprises a manual quad four-pole double-throw switch [1] consisting of a first single-pole double-throw switch, a second single-pole double-throw switch, a third single-pole double-throw switch and a fourth single-pole double-throw switch, and is characterized in that: a light-operated switch [2] is provided; the public end of the fourth single-pole double-throw switch of the manual quad four-pole double-throw switch [1] is connected with a 27Vpower supply; the normally-open contact of the fourth single-pole double-throw switch of the manual quad four-pole double-throw switch [1] is connected with the power supply input end of the light-operated switch [2] and a redundancy control switch position indicating lamp; the signal input end of the light-operated switch [2] is connected with a fourth redundancy control signal output end; and the signal output end of the light-operated switch [2] is connected with the fourth redundancy control signal output end of the flight control system. In the invention, the requirements of the novel flight control system can be met without replacing the conventional four-pole double-throw switch, and the research progress of the novel flight control system is ensured.

Description

technical field [0001] The invention belongs to the flight control technology and relates to the improvement of the redundancy control switch of the flight control system. Background technique [0002] Existing flight control system redundancy control switch is a manual quadruple four-pole double-throw switch composed of the first single-pole double-throw switch to the fourth single-pole double-throw switch, the first single-pole in the manual quadruple four-pole double-throw switch The four common terminals from the double-throw switch to the fourth single-pole double-throw switch are respectively connected with the first redundancy control signal output terminal to the fourth redundancy control signal output terminal of the flight control system, and the first four corresponding to the above four common terminals The normally open contacts of one single pole double throw switch to the fourth single pole double throw switch are respectively connected to the acquisition term...

AI Technical Summary

Problems solved by technology

This kind of redundancy control switch does not meet the requirements of the new flight control system, because the new flight control system requires adding a position indicator light of the redundancy control switch to give the position status of the redundancy control switch

However, the existing 4-pole double-throw switch has only 4 signal paths, which cannot give switch position information

At the same time there is no more space in the control box to replace the existing 4PDT switch with a 5PDT switch
