Method for determining the concentration of gas dissolved in cryogenic fuel during tests of rocket engines
Приведено обоснование необходимости определения концентрации растворённого газа в результате анализа представленной пробы раствора при испытаниях жидкостных ракетных двигателей на криогенных компонентах топлива. Изложены основные особенности способа, разработанного для оперативного определения концентрации гелия в жидком водороде. Приведены сведения о практическом использовании разработанного способа при экспериментальном определении характеристик агрегатов подачи жидкого водорода в двигатель. The article substantiates the need to determine the concentration of dissolved gas as a result of analysis of the presented sample of the solution during tests of liquid rocket engines on cryogenic fuel components. The main features of the method developed for the rapid determination of the concentration of helium in liquid hydrogen are described. Information is given about the practical use of the developed method in the experimental determination of the characteristics of liquid hydrogen supply units in the engine.
