DEVICE FOR LEAKAGE TEST OF PRESSURIZATION SYSTEM OF FUEL AND OXIDANT TANKS OF SPACE VEHICLE Russian patent published in 2004 - IPC

FIELD: space materiel, in particular, designing and operation of pressurization systems of fuel and oxidant tanks used in propulsion systems of space vehicles and in refuelling systems positioned on freight spaceships.

SUBSTANCE: the device has transducers of pressure in the tank-pressurezation lines, high-pressure gas bottle communicating with the gas chamber of the fuel and oxidant tanks, shut-off valves and gas pressure regulators as well as test fillers. The device uses also detachable by-pass-lines, each of them including a receiver, throttling device and an additional pressure transducer, one end of the by-pass line is connected to the test filler installed in the pressurization line at the inlet to the gas chamber of one of the fuel tanks, and the other - to the test filler installed in the fuel feed line at the outlet from the liquid chamber of the same fuel tank, the throttling device is installed in the detachable by-pass line at the end connected to the test filler installed in the pressurization line.

EFFECT: simplified and economic efficiency of tests of fuel and oxidant lines within the pressurization system.
