METHOD OF QUALITY CONTROL IN PRODUCTION OF SPACESHIP LIQUID PATH Russian patent published in 2011 - IPC B64G1/50 

FIELD: transport.

SUBSTANCE: invention relates to production of liquid paths and collectors of temperature control systems integrated with cellular panels of spaceship. Proposed method fabricating reference resistances and liquid path and measuring hydraulic resistances in parallel hydraulic lines by blowing. Measurement is performed continuously at identical ambient conditions and separately at identical temperature, humidity and consumption of blowing air. In measurement of hydraulic resistance of reference resistance and liquid path at the same flow rate of blowing air, absolute pressures at their outlets are measured. Measured hydraulic resistance is compared with tolerance defined from certain relationship. Said relationship allows for tolerable hydraulic resistance at above conditions of blowing and acceptance tests. Proposed method allows connecting parallel line to tested element with increased total hydraulic resistance and different from line connected to reference resistance.

EFFECT: valid quality control, reduced costs.
