According to the detachable flow resistance adjusting module, method and system of the space propulsion system, the detachable module type flow resistance adjusting device is adopted for an engine propellant supply system in the space propulsion field for the first time, the flow resistance adjusting efficiency and the production efficiency are improved, the weight and the use cost of a system product are reduced, and meanwhile, the flow resistance adjusting precision can be ensured.

Description

technical field [0001] The present invention relates to the technical field of flow resistance adjustment, in particular to a detachable flow resistance adjustment module of a space propulsion system and an implementation method thereof. Background technique [0002] With the development of aerospace technology, aerospace products have more and more precise control over the flow resistance of the engine pipeline, and more and more stringent weight control, and because many aerospace products require a suitable launch window, the production schedule requirements for many products are relatively strict, and at the same time It is also common for a product to be produced on multiple lines. [0003] At present, the flow resistance of many types of pipelines needs to be controlled with an accuracy better than 2%, or even 1%. According to the current flow resistance adjustment mode, one is to directly use the system product pipelines and valves for flow resistance debugging. Pipe...

Problems solved by technology

[0003] At present, the flow resistance of many types of pipelines needs to be controlled with an accuracy better than 2%, or even 1%. According to the current flow resistance adjustment mode, one is to directly use the system product pipelines and valves for flow resistance debugging. Pipeline cutting and cleaning, this mode can ensure the accuracy of flow resistance adjustment, but directly using the product pipeline for debugging, and then cutting and cleaning, there is a risk of excess material, affecting product safety, and increasing product weight, affecting the progress of the main product line

Another mode is to use the process pipeline for flow resistance debugging. After the debugging is completed, the debugged orifice plate is removed separately, and then installed into the system. This mode has little impact on the main line of the system product and will not generate extra However, due to the difference in the installation state of the orifice plate, it is difficult to control the accuracy of the flow resistance data at 2% after the orifice plate is removed and reinstalled to the product pipeline of the system

[0004] In view of the related technologies mentioned above, the inventor believes that there are problems of low flow resistance adjustment efficiency and low production efficiency, therefore, a technical solution needs to be proposed to improve the above technical problems
