ROCKET UNIT ENGINE PLANT Russian patent published in 2010 - IPC B64G1/40 

FIELD: transport.

SUBSTANCE: proposed invention relates to aerospace engineering, namely to rocket unit engine plant. Proposed engine plant comprises oxidiser cryogenic tank and/or fuel cryogenic tank, air valve and pipelines. T-tubes are added to pipelines connected with air valves. Inner space of every T-tube accommodates section of air valve control pressure pipeline with its one end communicated with air valve control pressure union and its other end welded to T-tube via adapter. Section of air valve control pressure pipeline is furnished with compensating element to compensate for temperature and mechanical displacements between air valve and T-tube at all stages of preparation and operation of rocket unit engine plant.

EFFECT: improved heat isolation of fuel tanks.
