Abstracts:

This work presents the theoretical and experimental justification for application of new type of materials - the combined porous-mesh materials (KPSM)- for the separation of gas from the liquid in the liquid-gas mixture flow in the real zero gravity in the fuel tanks of spacecrafts, final steps of carrier rockets and rockets' upper-stages. It is shown that KPSM work is accompanied with phenomena that do not appear while using meshy materials previously applied for this purpose. As a result, the efficiency of intratank devices (VBU) during multiple starts of liquid-propellant engine in the zero gravity greatly increases. In the final analysis, the use of KPSM in the VBU structure allows to minimize unusable fuel in tanks, and, thus, to raise total power mass efficiency of the spacecrafts mentioned.
