主　　题：actuating cylinder inner-lock core components workmanship requirements 

摘      要：Three kinds of landing gear actuating cylinder inner-locks of an aircrafi ： block ring lock, steel ball lock, finger lock are taken as the study object based on the mechanics, geometry, materials, technology etc and some aircrafi typical inner-lock practical applications. The working principle of the three typical actuating cylinder innerlocks are expounded and the stress and workmanship requirements of the three inner-lock core components are analyzed. The advantages and disadvantages of different kinds are compared and the characteristics and applications of the three inner-locks investigated. The research and analysis results provide valuable information for the actuating cylinder inner-lock of the aircraft landing gear design.
