This paper is aimed to investigate the difference of closed stage separation and separation with vent-window open for launch vehicles. Firstly, the separation sequence design and special environmental conditions are analyzed. Then, the working characteristics of electromechanical servo system which first applied in a kind of solid engine vehicle are presented. Subsequently, environmental adaptability of electromechanical servo under the closed stage separation condition in terms of disturbed moment and close pressure and thermal flow is analyzed. The presented method of adaptability analysis can be applied to other servo systems design for closed stage separation condition.
