Abstract

The invention discloses a multifunctional atomization test system. The system comprises a high-pressure atomization test system, a normal-pressure atomization test system and a propellant supply system; the high-pressure atomization test system comprises a high-pressure atomization cabin and a first spray cone angle measuring device; the normal-pressure atomization test system comprises a normal-pressure spray device, a second spray cone angle measuring device and a spray particle size measuring device; the normal-pressure spray device comprises a nozzle and a nozzle height adjusting frame; the spray particle size measuring device comprises a height lifting frame, a sliding rod and a laser particle analyzer; and the propellant supply system can be used for providing gas-liquid or liquid-liquid two-component propellants for a nozzle in the high-pressure atomization cabin or a nozzle on the nozzle height adjusting frame. With the system adopted, atomization tests in various environments such as a normal-pressure atomization test, a high-back-pressure atomization test and an atomization test under flow pulsation can be carried out, atomization tests of various spraying media can also be carried out, and the spray cone angle and the liquid film breaking length can be accurately measured.

Description

technical field [0001] The invention relates to the field of rocket engines, in particular to a multifunctional atomization test system. Background technique [0002] Liquid rocket engines play an important role in many space activities such as spacecraft launch, attitude control, and orbit transfer, and are widely responsible for many space missions such as manned moon landing, Mars exploration, and deep space exploration. In order to ensure the smooth progress of space missions, it is necessary to ensure that the liquid rocket engine has high reliability, but the instability of high-frequency combustion has become an important factor that inhibits its development. [0003] Since the high-frequency combustion instability test of a full-scale liquid rocket engine is high-risk, and the test cost is high and the processing cycle is long, in order to improve the test efficiency, researchers often carry out scale-down simulation tests, and atomization is an important part of the...
