液体火箭发动机是液体导弹、运载火箭及航天器的主要动力装置。燃烧室内燃气温度可达3000-4800K，喷管出口燃气流最高达6马赫，这样高压、高温、高速的燃气流将产生巨大的对流热流和辐射热流，传向壁面。为防止因壁温过高而使室壁烧毁变形，液体火箭发动机常采用液膜冷却降低壁温，即在喷注器边缘或燃烧室适当位置专门设置一圈或多圈小孔，喷出燃料，形成贴壁液膜或气膜，以把室壁与燃气隔开，减少燃气向室壁的传热，保护室壁不致过热烧蚀。Liquid rocket engines are the main power devices for liquid missiles, launch vehicles and spacecraft. The gas temperature in the combustion chamber can reach 3000-4800K, and the gas flow at the nozzle outlet can reach up to Mach 6. This high-pressure, high-temperature, and high-speed gas flow will produce huge convective heat flow and radiation heat flow, which are transmitted to the wall. In order to prevent the chamber wall from being burned and deformed due to excessive wall temperature, liquid rocket engines often use liquid film cooling to reduce the wall temperature, that is, one or more circles of small holes are specially set up at the edge of the injector or at appropriate positions in the combustion chamber to eject fuel. , forming an adhering liquid film or gas film to separate the chamber wall from the gas, reduce the heat transfer of the gas to the chamber wall, and protect the chamber wall from overheating and ablation.
而冷却路射流的均匀性直接影响到燃烧室壁的冷却效果，当均匀性较差时，会出现局部温度较高，严重时影响发动机工作可靠性，因此需要检测冷却路射流均匀性，目前主要采用人工收集法来进行检测。The uniformity of the cooling path jet directly affects the cooling effect of the combustion chamber wall. When the uniformity is poor, local temperatures will be high, which seriously affects the engine's operating reliability. Therefore, it is necessary to detect the uniformity of the cooling path jet. Currently, it is mainly Manual collection method is used for detection.
但是，随着燃烧室室压的升高，同样推力量级下的产品尺寸大幅减小，相邻冷却孔的间距相应变小，使得常规检测工装收集各股流量操作困难，导致检测射流均匀性较为困难。However, as the chamber pressure of the combustion chamber increases, the size of the product at the same thrust level decreases significantly, and the spacing between adjacent cooling holes becomes smaller accordingly, making it difficult for conventional detection tooling to collect each flow, resulting in the detection of jet uniformity. More difficult.

其中，每个所述导流段2均包括导流面21，每个冷却孔1射出的冷却路射流束均出射至相应导流段2的导流面21上。Each of the guide sections 2 includes a guide surface 21 , and the cooling path jet beam emitted from each cooling hole 1 is emitted onto the guide surface 21 of the corresponding guide section 2 .
在具体实施过程中，喷注器或冷却环的多个冷却孔1与导流结构的多个导流段2的入口端对应连通，在进行冷却路射流均匀性检测时，每股冷却路射流束从冷却孔1流出后，均能出射至相应导流段2的导流面21上，沿着该导流面流至导流段2出口端，最后通过导流段2出口端将冷却路射流束导入收集结构中，利用各个收集结构中所收集的冷却路射流束质量，计算出各导流段所收集的流量的平均值与散差，从而对冷却路射流的均匀性进行评价。而且沿导流段2的入口端至导流段2的出口端的方向，相邻两个导流段2的中心线之间的距离逐渐增加，即在导流段2中流淌的两股相邻冷却路射流束

The angle between them. With this arrangement, the jet beam flowing out from the cooling hole 1 can flow to the guide surface 21 to prevent the jet beam from splashing out of the guide section 2 and affecting the amount of cooling jet beam collected by the collection structure, thereby affecting the detection results.
