The invention discloses a full-ring micro-size backflow combustor tester which comprises an outer casing, an inner casing, a guiding device, a rectifying device, a combustor inner wall, a combustor outer wall, an exhaust pipeline, an exhaust nozzle, a turbine guider and a plurality of measurement rakes. A containing space is formed by the outer casing and the inner casing in a defined mode. The outer casing is provided with an air inlet channel. The guiding device and the rectifying device are sequentially arranged in the air inlet channel in the air inlet direction. The combustor inner wall and the combustor outer wall are arranged in the containing space and respectively provided with one air hole, a combustor is formed by the combustor inner wall and the combustor outer wall in a defined mode, and the air holes are communicated with the containing space and the combustor respectively. The combustor is provided with an outlet. One end of the exhaust pipeline is connected with the outlet of the combustor. One end of the exhaust nozzle is connected with the other end of the exhaust pipeline. The turbine guider is connected with the other end of the exhaust nozzle. The measurement rakes are distributed on the outlet of the combustor in the circumferential direction of the combustor and are comb-shaped rakes. The manufacturing cost of the full-ring micro-size backflow combustor tester is low, and the measurement result is accurate.
Description
technical field [0001] The invention relates to the field of turbine engines, in particular to a full-circle micro-size recirculation combustion chamber tester. Background technique [0002] In the related art, the backflow combustor tester uses a part of the combustion chamber (such as 180 ° or 120 ° in the entire ring) to test, and the measured combustion chamber outlet parameters can not truly reflect the combustion of the entire ring on the engine. The working status of the room. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, an object of the present invention is to provide a full-circle micro-sized recirculation combustion chamber tester with low manufacturing cost and accurate measurement results. [0004] The full-circle micro-sized reflow combustor tester according to the embodiment of the present invention includes: [0005] an outer casing and an i...
