The paper presents theoretical and experimental substantiation of the prospects to use materials of the new type, i.e. the combined porous-mesh materials (CPMM), in the in-tank devices (ITD) structures of spacecraft propulsion systems and upper stages to ensure multiple liquid-propellant rocket engine start in practical zero gravity. It is shown that CPMM operation was accompanied by phenomena that were missing, when using mesh materials previously used for this purpose, the so-called mesh separators (MS). It is concluded that at present it should be considered expedient to widely introduce CPMM in the ITD structure elements, since in this capacity the CPMM properties are noticeably superior to those of conventional MS. As a result, the ITD efficiency based on CPMM increases significantly, which finally makes it possible to minimize unusable fuel residues in the tanks and, thereby, increase the energy-mass efficiency of the aerial vehicle as a whole.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
