Outer two-channel airflow entraining structure for aero-engine combustion chamber test

The invention discloses an outer two-channel air flow entraining structure for an aero-engine combustion chamber test. According to the air entraining structure, air flow in an outer two-channel is exhausted to the downstream tail end, and the actual working condition can be simulated. Due to the fact that the air entraining structure can discharge air flow in the outer two channels to the downstream tail end, actual working conditions can be simulated, the problem that in the prior art, the air flow in the outer two channels flows out of the middle and affects the flow field of the outer two channels is solved, and the stability of the flow field of the outer two channels is guaranteed. 本发明公开了一种航空发动机燃烧室试验的外二股通道气流引气结构，将外二股通道内气流向下游末端排出能模拟实际工况的引气结构。由于引气结构能实现外二股通道内气流向下游末端排出能模拟实际工况，解决了现有技术外二股通道气流在中部流出存在影响外二股通道流场的问题，保证了外二股通道流场的稳定性。
