Abstract:
Since the parameters of pipes and containers were changed after the test-stand technological renovation for overload test, the inlet pressure of the oxidizer was required to be raised from the steady phase to the overload phase in the process of engine test running within a specific time period. An error was made in the pressurization calculation for the tank during the first test. This made the pressurization valve act several times. In order to get rid of this phenomenon and get the actual pressurization ability of the test stand, the influencing factors and the test data were analyzed and calculation process was adjusted to make the tests to be successfully conducted. The result indicates that the method is correct.
