DEVICE TO FILL IN AND DISCHARGE OXIDISER OF ROCKET BOOST VEHICLE Russian patent published in 2009 - IPC B64G1/40 

FIELD: aircraft engineering.

SUBSTANCE: invention relates to space engineering, namely, to filling in and discharging oxidiser from the rocket boost vehicle. The proposed device comprises filling and discharge valves fitted on the oxidiser tank, filling and discharging pipelines and hydraulic split-joint arranged on the fuel tank and used in uncoupling aforesaid filling and discharging lines when boost vehicle gets separated from the rocket launcher. The sections of aforesaid filling and discharging pipelines are connected to the common pipeline fastened on the fuel nark frame with the help of a spherical support representing a spherical insert - thermal bridge, clamp with a spherical surface, thermal bridge and bracket with slots. Aforesaid spherical support redistributes angular shifts between the sections of aforesaid filling and discharging lines and the common pipeline. Both said sections are furnished with the bellow-type angular shift and linear shift compensators. The common pipeline incorporates additional bellow-type angular shit compensator. The said compensators served compensate for the device shifts relative to attachments points on the fuel and oxidiser tanks.

EFFECT: reduced weigh, compensation of relative shifts of pipelines.
