Abstract

The invention belongs to the field of ignition performance testing of main combustion chambers, and particularly relates to an outlet cooling section for ignition performance testing of a main combustion chamber. The outlet cooling section comprises a cooling cavity (2) and a water supply ring pipe (3). The cooling cavity (2) is sleeved with a water cooled jacket; the water cooled jacket is provided with a water cooled jacket water outlet (4) and a water cooled jacket water inlet (9); the cooling cavity (2) is provided with two or more nozzles; the water supply ring pipe (3) is coaxially arranged on the outer side of the cooling cavity (2) in a sleeving manner through a supporting rod (11); the water supply ring pipe (3) is provided with a flow distribution hose (10) matched with the nozzles; the flow distribution hose (10) can be connected with the nozzles; and the water supply ring pipe (3) is further provided with a water supply ring pipe water inlet (8). According to the outlet cooling section for the ignition performance testing of the main combustion chamber, the water spraying amount is adjustable; the cooling effect can be improved; and the service life is prolonged.

Description

technical field [0001] The application belongs to the field of ignition performance test of the main combustion chamber, in particular to an outlet cooling section used for the ignition performance test of the main combustion chamber. Background technique [0002] The development of an aero-engine requires the support of a large number of component tests, and the ignition / flame-off test of the main combustion chamber is one of the important component tests. During the ignition / flame-off test of the main combustion chamber, the gas at the outlet of the test piece has the characteristics of high temperature. In consideration of saving the material cost of the exhaust system of the tester, reducing the difficulty of exhaust system design, and ensuring the safety of the test, it is necessary to timely discharge the high-temperature exhaust gas. Cool down. Therefore, it is necessary to design an exhaust cooling section, which is installed between the outlet of the test piece and...
