The Design and Implementation of Control Mode Switching Equipment for a Type of In-flight Simulator

The In-flight simulator can simulate the flight of the new aircraft before it takes off, and it plays a very important role in improving the design of the new aircraft, and it is an important link in the process of aircraft development. This paper analyzes the cross-linking relationship between the control instructions of the original aircraft and the variable stability aircraft, designs the control mode switching circuit, and gives the overall composition and implementation method of the control mode switching equipment. The gradual loop and double redundancy design are adopted in the design, which effectively ensure the stability and reliability of the equipment operation and realize the switching of the control command of the rudder surface between the original aircraft flight control system and the variable stability flight control system. The test results show that the equipment works well and meets the requirements of flight test.
