FLOW GUIDE STRUCTURE AND DEVICE FOR MEASURING UNIFORMITY OF COOLING PATH JET

Disclosed in the present application are a flow guide structure and device for measuring the uniformity of a cooling path jet, which structure and device relate to the technical field of liquid rocket engines, and solve the problem of it being difficult for a conventional measuring tool to perform collection and measuring when the distance between adjacent cooling holes is too small. The flow guide structure for measuring the uniformity of a cooling path jet comprises a plurality of flow guide sections circumferentially arranged on an outer side of the flow guide structure. In the direction from inlet ends of the flow guide sections to outlet ends of the flow guide sections, the distance between center lines of every two adjacent flow guide sections gradually increases, the plurality of flow guide sections correspondingly communicate with a plurality of cooling holes, and each flow guide section is configured to guide a collected cooling path jet beam to an outlet of the corresponding flow guide section, and
