HEAT EXCHANGERS OF RD119 ENGINE OF "COSMOS" LAUNCH-VEHICLE
This article supplements the series of articles dedicated to improvement of heat exchangers of NPO Energomash development included in LRE composition and intended for pressurization of propellant tanks of launch-vehicles. Shell-tube nitrogen evaporator of RD107 and RD108 engines, cylindrical heat exchanger of RD171 engine and plate-fin pressurization unit of single-chamber LRE had been considered previously. Principle scheme of pressurization system of propellant tanks of second stage of "Cosmos" LV is presented in article. Descriptions of designs and coolants flow schemes, technological and overall-mass characteristics, features of development of designs and main parameters of shell-tube evaporator of oxygen and mixer of RD119 engine are presented.
Keywords: system of LV propellant tanks pressurization, heat exchanger, evaporator, mixer, pressurization unit, heat exchanger.
