固体推进剂超高压燃速测试压强平衡调节系统
摘要：
一种固体推进剂超高压燃速测试压强平衡调节系统，本发明由气液混合注塞气缸、气动比例调节阀、气动水增压泵、控制系统和高压燃烧室组成。气动水增压泵用于给高压燃烧室提供液压；气液混合注塞气缸和气动比例调节阀联机使用，用来调节恒定样品燃烧过程中高压燃烧室内的压强波动。本发明实现了用≤1MPa的气体驱动、控制和调节100MPa的液体压强，从而达到推进剂燃速测试时样品燃烧过程的恒压环境，将推进剂燃速测试压强由20MPa提高到100MPa。
摘要（英）：

The invention relates to a solid propellant ultra-high pressure burning rate test pressure balance adjustment system. The system provided by the invention consists of a gas-liquid mixed plugging cylinder, a pneumatic proportional regulating valve, a pneumatic water boosting pump, a control system and a high pressure combustion chamber. The pneumatic water boosting pump is used to provide hydraulicpressure for the high pressure combustion chamber. The gas-liquid mixing plugging cylinder and the pneumatic proportional regulating valve are used together to adjust the pressure fluctuation in a high pressure combustion chamber during a constant sample combustion process. According to the invention, gas less than or equal to 1 MPa is used to drive, control and adjust the liquid pressure of 100MPa; a constant pressure environment of the combustion process of a sample during the burning rate test of an propellant is realized; and the burning rate test pressure of the propellant is improved from 20 MPa to 100 MPa.
