Refrigerating of high-boiling rocket fuel is needed to reduce its density and to create cold reserve for equalization of fuel heating during preparing and launching operations. Liquid nitrogen is cheap and ecologically clean product, which can be easily used as a source of cold in rocket fuel preparing systems. Refrigerating systems with liquid nitrogen injection, intermediate heat carrier and heat exchanger are used in temperature preparing of high-boiling rocket fuel components with relatively high freezing point. The operation principle of such system is based on liquid nitrogen injection into heat carrier and refrigerating a rocket fuel component with recuperative heat exchanger. The paper considers simulation techniques and results of such a system performance.
