Abstract
The paper presents the study of heat transfer processes during prelaunch decreasing expenditure highways propulsion units (PU) upper stage (US) launch vehicles (LV) and cryogenic systems of the test bench (TB). Based on the consideration of the equations of conservation of mass and energy as applied to gas-cushion tank and the volume of the tank is filled with cryogenic fluid, the methods of mathematical simulation of processes of cooling. According to the results of bench and flight tests control coefficients are specified closing dependences on heat transfer and friction in heat capacity of the elements. TB and PU. The results of calculation and experimental studies of the processes of cooling consumable hydrogen and oxygen arteries obtained at bench and flight tests of RB, can be used for verification of computer models calculate during cryogenic systems TB and PU.

В работе проведены исследования процессов теплообмена при предстартовом захолаживании расходных магистралей двигательных установок (ДУ) разгонных блоков (РБ) ракет-носителей (РН) и в криогенных системах испытательного стенда (ИС). Результаты расчетно-экспериментальных исследований процессов захолаживания расходных водородных и кислородных магистралей, полученные при стендовых и летных испытаниях РБ 12КРБ, могут быть использованы для верификации компьютерных моделей расчета теплообмена криогенных систем ИС и ДУ.
