DEVICE FOR FIXATION OF ROTARY PLATFORMS FOR FASTENING OF USEFUL LOADS

摘要

FIELD: transportation. ^ SUBSTANCE: invention is related to devices for fixation of rotary platforms for fastening of objects, mostly spacecrafts and other useful loads, on adapters or instrumentation modules of carrier rockets and may be used in rocket-space equipment in case of group launching. Device for fixation of rotary platforms for fastening of useful loads comprises mechanical locks that retain rotary platforms on bearing structure of carrier rocket by means of pyro-units. Device is equipped with cable system that connects mechanical locks of every rotary platform with multiprong star, prongs number of which is equal to number of rotary platforms. Multiprong star is fixed on bearing structure by means of shaft with the possibility of turn and is retained against turn by pyro-unit that interacts with lever that is fixed on mentioned shaft. Every cable that connects with its ends mechanical lock of rotary platform and appropriate sprong of multisprong star is installed along bearing structure by means of rollers fixed in it and is tightened with tender. ^ EFFECT: provision of simultaneous symmetrical turn of rotary platforms group for their symmetrical turn by single pyro-unit from accumulator battery of low capacity with minimum effect at useful load. ^ 7 dwg
