Problems solved by technology

Especially before the engine is started, during the working process, and after the engine is shut down, the test system needs to blow off and inflate many key parts of the engine. If the excess is not strictly controlled, it is easy to cause uneven combustion inside the engine during the test run and aggravate the wear of parts. , Abnormal valve opening and closing, engine ignition blockage and abnormality, which will cause premature failure, damage, or even abnormal shutdown of important components such as turbo pumps, resulting in the final failure of the test

Embodiment Construction

[0021] For the gas filtration of the gas distribution system of the liquid oxygen kerosene engine test, for the stored gas after gasification, multiple filters are set to reduce the excess, and in this way, the accuracy is continuously improved, the gas impact is reduced, and the filtration is guaranteed. The filter quality and reliability of the filter can be obtained to obtain pure nitrogen for testing, so as to prevent excess substances from entering the engine and causing hidden dangers in engine operation.

[0022] Such as figure 1 As shown (the figure only shows a schematic diagram of one gas delivery unit and gas distribution unit, and the other multiple channels are the same, so they are omitted), the gas supply system includes a liquid nitrogen source 1, a gas production unit 2, multiple gas Delivery unit 3 and multiple gas distribution units 4;

[0023] One end of the gas production unit 2 is communicated with the liquid nitrogen gas source 1, and the other end is r...

Abstract

The invention belongs to the technical field of aviation and space technology, and in particular discloses a liquid oxygen / kerosene engine test gas supply system which specifically comprises a liquid oxygen source, a gas production unit, a plurality of gas conveying units and a plurality of gas allocation units. The liquid oxygen / kerosene engine test gas supply system is characterized in that one end of the gas production unit is communicated with the liquid oxygen source; the other end of the gas production unit is communicated with the plurality of gas conveying units; each gas conveying unit is communicated with the plurality of gas allocation units. By the adoption of the liquid oxygen / kerosene engine test gas supply system, the purity of a gas can be controlled from the source, foreign matters can be prevented from entering an engine, and success of a liquid oxygen / kerosene engine ground test can be ensured.

Description

technical field [0001] The patent of the invention belongs to the technical field of aviation and aerospace, and relates to a liquid oxygen / kerosene engine test gas supply system. Background technique [0002] The ground test of the liquid rocket engine is an important means to evaluate the performance of the engine, verify the rationality of the design scheme, and check the acceptance of the engine. Evaluate the test method and evaluate the performance and processing quality of the engine or assembly. In order to ensure the gas requirements of various functions used in the liquid rocket engine ground test, it is necessary to establish a gas supply system to provide gas sources with different pressures and different flows according to relevant requirements. The gas supply system mainly includes a gas source, a gas production unit, a gas delivery unit, and a gas distribution unit. The gas from the gas source passes through the above three units and finally enters the engine ...
