A Study on the Design of Electromechanical Safety Locking Device of Rail Launcher for Air Platform

Rail launchers for air platforms have store locking devices. If excessive force is applied to the launcher beyond the allowable store locking force, the locking device will unintentionally release the store. In order to prevent the inadvertent release, an electromechanical safety locking device(ESLD) is newly applied to the rail launcher. The ESLD includes a structure which supports the end-tip of the detent to prevent the detent from rotating except at the moment of launch. The ESLD prevents detent rotation even if vibration or impact is applied. In this paper, the performance of the ESLD was verified through dynamic analysis and tests. For the analysis, vibration test profile, shock test profile and actual Barrier Arresting Kit pass-through measurement data were used. The analsys was performed by applying these values to the model. For the tests, vibration tests, shock tests and Barrier Arresting Kit pass test were conducted.
