The 2nd stage servo-mechanism system design for the future liquid oxygen-kerosene manned launch vehicle is introduced. Based on requirement analysis and current development of both home and abroad, a highly reliable system architecture, namely, triple redundancy digital control and dual redundancy hydraulic power, is put forward, with a simple in-flight-cold-start approach, a new kerosene motor power assembly, and a new model of totally monolithic self-contained servo-mechanism analyzed. Study shows that the system design is highly reliable and easy to operate and maintain.
