Separation device for spacecraft unpressurized platforms based on isogrid structures

Design solution of the separation device for spacecraft unpressurized platforms with foundation central tube based on isogrid carbon structure is presented. The structure analysis based on the optimal mass, separation parameters, reliability under the worst operational conditions, etc. was performed for the new launch adapter. As a result, the new launch adapter was developed, which allows to eliminate additional spacers and interfaces, tightening frames for adapter and load-bearing structure at 12 uniformly spaced points on the circle (mechanical locks). The designed launcher adapter allows to unify the structure of incoming elements and to use different configurations (of locks, injector springs, etc.). The launch adapter has better characteristics, as compared to foreign prototypes, depending on mass structure of SV to be launched. At the present time the launch adapter structure is successfully used in «Amos-5», «Telkom-3», «Yamal-300К», «Louch-5B» satellites.
