DEVICE FOR FILLING AND DRAINING ROCKET BOOSTER OXIDISER Russian patent published in 2012 - IPC B64G1/40 B64G5/00 

FIELD: transport.

SUBSTANCE: invention relates primarily to surface operation of space rocket equipment. Proposed device comprises filling and draining pipeline sections and common pipeline secured on fuel tank frame 4 by means of brackets 12 and spherical support 16. Filling pipeline section has no relative displacement compensators. Inner surface of support 16 features cylindrical shape changing into that of truncated cone. The latter limits displacement of spherical insert 8 toward oxidiser tank. Common pipeline surrounds fuel tank external side and features a lyre shape to compensate relative displacements of the device. Spherical insert 8 slides on cylindrical surface of the support while bellows compensators of angular and linear displacements of draining pipeline section (not shown) ensure compensation of difference in relative displacements of aforesaid pipeline sections. This design allows ~ 25%-reduction in booster weight.

EFFECT: reduced weight of booster.
