本发明涉及一种针栓式发动机性能测试装置，具体涉及一种冷却液射流均分件性能测试装置及方法。The invention relates to a performance testing device of a pintle type engine, in particular to a performance testing device and method of a coolant jet equalizer.
背景技术Background technique
针栓式发动机工作时氧化剂和燃料在喷注器内撞击雾化形成高温燃气后喷出，再进入推力室身部，由于高温燃气的温度较高，为了避免推力室身部被烧蚀，一般会采用冷却液对推力室身部进行冷却，即在针栓式发动机的喷注器出口设置冷却液射流均分件7。参照图1和图2，冷却液射流均分件7为环形薄板件，其侧壁沿周向均布多个冷却液射流孔701；冷却液射流孔701与冷却液射流均分件轴线成一定夹角，且贯通冷却液射流均分件7的侧壁。When the pintle engine is working, the oxidant and fuel collide and atomize in the injector to form high-temperature gas, which is sprayed out and then enters the body of the thrust chamber. Due to the high temperature of the high-temperature gas, in order to avoid ablation of the body of the thrust chamber, generally Coolant is used to cool the body of the thrust chamber, that is, a coolant jet equalizer 7 is arranged at the injector outlet of the pintle engine. Referring to Fig. 1 and Fig. 2, the coolant jet equalizer 7 is an annular thin plate, and its side wall is uniformly distributed with a plurality of coolant jet holes 701 along the circumferential direction; the coolant jet holes 701 form a certain angle with the axis of the coolant jet equalizer , and penetrate the side wall of the cooling liquid jet flow distribution member 7 .
冷却过程中，如果冷却液分布不均匀就容易将推力室身部烧蚀，因此，对冷却液射流均分件7进行性能测试，并选取合格的冷却液射流均分件进行装配就至关重要。During the cooling process, if the coolant is not evenly distributed, the body of the thrust chamber will be easily ablated. Therefore, it is very important to perform a performance test on the coolant jet splitter 7 and select a qualified coolant jet splitter for assembly. .
冷却液射流均分件7的性能测试包括射流观察、给定反压和流量流阻测试。由于冷却液射流均分件7厚度很小，其外径尺寸远大于厚度尺寸，且测试过程中很容易发生折弯现象，导致测试结果不准确，故很难准确模拟实际工况，因此，目前并无专门适用于此类冷却液射流均分件的测试装置，导致此类冷却液射流均分件无法进行性能的精确测试。The performance test of the coolant jet equalizer 7 includes jet observation, given back pressure and flow resistance test. Since the thickness of the coolant jet equalizing part 7 is very small, its outer diameter is much larger than its thickness, and it is easy to bend during the test process, resulting in inaccurate test results, so it is difficult to accurately simulate the actual working conditions. Therefore, at present There is no test device specially suitable for this type of coolant jet splitter, resulting in the inability to accurately test the performance of this type of coolant jet splitter.
