LIQUID JET COOLER BASED IMPROVED CRYOGENIC BENCH COMPLEX

I.I. Petukhov, Y.V. Shakhov

Variants of modernization of the liquid hydrogen ground-based storage, cooling and refueling system of the superheavy Energy launch vehicle Block C by liquid jet cooler replacement of the traditional heat exchangers were considered. In addition to large stand design simplification and materials consumption reduction it allow to realized the closed circuit circulation of the liquid hydrogen fuel at the launch vehicle fuel tank thermostating. This provides both cryogenic fuel component saving and the fueling and thermostating processes safety enhancement. Proposed in this article technical solutions can be used for development of new and modernization of existing systems for storage, cooling and fueling operation for liquid hydrogen launch vehicle fuel tank.

Key words: liquid hydrogen, rocket and space technology, bench and starting systems, evaporative cooling, cooling vessel, gas ejectors, liquid jet cooler, safety.
