DEVICE TO DISCHARGE LIQUID OXYGEN VAPORS FROM CARRIER ROCKET SIDE BLOCK OXIDISER TANK

摘要

FIELD: transport.;SUBSTANCE: invention relates to carrier rocket ground fueling equipment. Proposed device comprises vapor bleeding-off element with its one end secured to carrier rocket side block fairing flange (4). Said element has two bellows rigidly jointed by branch pipe. One of said bellows is made from nonmetal material inert to cryogenic fuel vapors. It has breaking groove (7), while flange cylindrical surfaces have circular grooves (8) to accommodate semi-rings (9). The latter interact by their face surfaces extending beyond outer diametre of the flange cylindrical surface with inner face surfaces of pressure rings ledges (11). Semi-rings (9) can turn about bellows flange cylindrical surfaces to interact with side fairing flanges (4). Face surfaces of the latter has circular ledges (12) and (13) arranged on the side of nonmetal bellows. Said ledges thrust against face surfaces of nonmetal bellows to ensure joint tightness. Note also that vapor bleeding-off element is furnished with rope suspension (14) with its one end secured to one of the flanges of branch pipe (3) and another end secured on veering boom. The other end of vapor bleeding-off element is rigidly fixed on the flange of vapor bleeding-off line arranged on said boom (not shown in the figure).;EFFECT: expanded operating performances due to possibility to work in premises thanks to vapor tight bleeding-off.;3 dwg
