DRAIN DEVICE FOR CRYOGENIC COMPONENT OF ROCKET ACCELERATING UNIT WITH DISMOUNTABLE CELL Russian patent published in 2015 - IPC B64G1/00 

FIELD: transport.

SUBSTANCE: invention relates to aerospace engineering, particularly, to cryogenic component draining from cryogenic tank of rocket accelerating unit in the configuration of space rocket. Drain device for cryogenic component of rocket accelerating unit with dismountable cell consists of drain valve, drain pipeline and angular motion compensator in configuration of drain pipeline. The drain pipeline is made of two parts interconnected by in-flight separable coupling. The first part of drain pipeline passes inside rocket accelerating unit. In the first part of drain pipeline, flexible element and additional angle motion compensator are introduced. Angle motion compensator and additional angle motion compensator are connected by flexible element. The second part of drain pipeline equipped with line motion compensator passes through dismountable cell and is brought outside of rocket accelerating unit.

EFFECT: providing reliable operation of drain line and fire and explosion safety of rocket accelerating unit with dismountable cell.
