AI Technical Summary

Technical Problem

Existing simulators cannot effectively simulate the side stick jamming of pilots in the loop, resulting in unrealistic test scenarios and difficulty in accurately assessing the side stick jamming state.

Method used

A test device was designed, comprising a comprehensive control console, a controller, a data acquisition unit, and a locking mechanism. The device acquires the position of the side rod in real time and locks or releases the side rod according to preset commands. The device utilizes a motor-controlled gear locking device and a linkage mechanism to achieve the actual locking and releasing of the side rod.

Benefits of technology

It enables real-time jamming of the pilot's side stick in the loop, simulating the actual hardware jamming state, improving the realism of the test scenario, and meeting the needs of maneuverability and safety assessment.

Abstract

A test apparatus for real-time locking of a side rod includes an integrated control console for injecting signals; a controller connected to the integrated control console to receive input signals from the integrated control console and issue commands according to the signals; a data acquisition unit connected to the controller to acquire the real-time position of the side rod and transmit the position to the controller; and at least one locking mechanism connected to the controller to receive commands from the controller and lock or release the side rod according to the commands. When the controller receives a signal indicating that the side rod is locked at a real-time position, the controller directly issues a locking command to the locking mechanism to lock the side rod. When the controller receives a signal indicating that the side rod is locked at a preset position, the controller compares the real-time position with the preset position, such that when the side rod moves to the preset position, the controller issues a locking command to the locking mechanism to lock the side rod.
