ROCKET STAGE Russian patent published in 2002 - IPC

FIELD: rocketry; instrumentation sections with rod frame at group injection of spacecraft. SUBSTANCE: stage includes instrumentation section with rod frame mounted on body, spacecraft separation system in form of four brackets with pyro pushers secured on butt of rod frame by means of threaded studs with nuts, as well as main and accompanying spacecraft. Fitted on studs of frame are trough-shaped brackets with beads inside which brackets with main spacecraft separation system are mounted on the same studs; platform with two parts projecting as cantilever are secured on said beads; projecting parts have seats for mounting accompanying spacecraft. Cantilever parts of platform are strengthened with V-shaped rod struts whose free ends are secured on platform and engaged ends are secured on brackets of instrumentation section. Total height of trough-shaped brackets and platform for accompanying spacecraft does not exceed height of brackets for mounting main spacecraft. EFFECT: reduced mass of stage at preset parameters of rigidity of rod frame and platform; increased zones of location of main spacecraft. 9 dwg
