Clean air distributing device and clean air distribution method for plume testing platform

Abstract

The invention provides a clean air distributing device and a clean air distributing method for a plume testing platform, which are used for distributing clean air for a vacuum plume effect testing system in testing. The clean air distributing device comprises a clean air generating system and a clean air delivery system, wherein the clean air generating system is used for generating clean air andstoring the same and comprises an air compressor, an oil-water separator for purifying air and an air storage tank; the clean air delivery system is used for filtering, pressure reduction and delivery of the air and comprises a main control pipeline and two auxiliary control pipelines. The clean air distributing method includes: air compressed by the air compressor is purified by the oil water separator and stored in the air storage tank, then is delivered to the main control pipeline, is delivered to the two auxiliary control pipelines under control of the main control pipeline, and is finally delivered to the vacuum plume effect testing system in testing. The clean air distributing device and the clean air distributing method for the plume testing platform are capable of meeting varioustesting requirements of satellite thermal vacuum testing and plume tests of electric propulsion motors and chemical propulsion motors, and can stably and flexibly supply clean air for testing.

Description

technical field [0001] The invention belongs to the field of vacuum science and technology, and in particular relates to a clean air gas distribution device and a gas distribution method required in satellite thermal vacuum tests and electric propulsion and chemical propulsion engine plume tests. Background technique [0002] The "Vacuum Plume Effect Test System" (multifunctional plume test platform) of Beihang University is a multi-purpose test device, which is mainly used for aerospace attitude and orbit control engine plume test research, and also takes into account thermal vacuum tests such as satellites. Due to the wide variety of tests that can be carried out on the plume test platform, the test needs to be equipped with an air source, and the air pressure required for different purposes is different, which leads to the complexity of the pipeline of its supporting clean air distribution device and requires a large number of components to be adjusted. The air pressure i...
