AI Technical Summary
Existing helicopter flight control system functional testing devices cannot realistically simulate complex motions, cannot be applied at the pilot's hand grip points, and occupy a large space and are complex to control, resulting in low testing accuracy and long testing cycles.
The motor torque is amplified by using gear transmission. The design includes a control stick adapter unit, force sensor, screw drive unit, and universal deflection unit, enabling the control stick to move in curves and be directly loaded at the hand grip point. The structure is compact and the control is simple.
It achieves real loading at the driver's hand position, reduces the space requirement of the device, improves the accuracy and efficiency of the test, and can meet the verification of airworthiness requirements.
