Elastic feed systems of fuel tanks

The article presents the results of experiments, bench test facilities and studies of corrosion resistance, operability of materials, units and assemblies of feed systems with long-term simulation of real resource testing of fuel tanks with environment simulation of the space station «Fobos-Ground». The results of the tests showed that by the end of the flight under flight conditions of spacecraft transfer module the expected gassing in the tank with oxidizer should be 0.16 l, and 0.02 l in a tank with fuel, if the leakage of the elastic feed systems is 1,0•10 -3 l μm Hg/s. Efficiency (constructive integrity) provides for transfer module flight duration of 510 days. Amilin and heptyl components met the requirements of normative and technical documentation before and after the tests.
