AI Technical Summary

Technical Problem

During ground taxiing, using the main engine is inefficient, consumes a lot of fuel, and requires manual operation of the towing vehicle, which wastes time and cannot meet different speed requirements.

Method used

Design a dual-speed ratio reducer with power separation function, including housing assembly, first clutch assembly, planetary assembly, disengagement and engagement assembly, etc. By controlling the state switching of clutch and brake, two reduction ratios and power separation function are realized, and the aircraft wheels are driven by electric actuator.

Benefits of technology

By using electric motors to drive the aircraft to taxi without using the main engine, different speed requirements can be met, achieving power separation, saving fuel consumption and scheduling time, and improving economic efficiency.
