Study and Analysis of a Landing Gear Actuating Cylinder Inner-lock

摘要

Three kinds of landing gear actuating cylinder inner-locks of an aircraft:block ring lock,steel ball lock,finger lock are taken as the study object based on the mechanics,geometry,materials,technology etc and some aircraft typical inner-lock practical applications.The working principle of the three typical actuating cylinder inner-locks 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.
