Embodiment Construction
[0051] The present invention is further illustrated below by means of examples, but the present invention is not limited thereto within the scope of examples.
[0052] Such as figure 1As shown, the present embodiment provides a full-scale fan-supercharger stage performance test device for testing the fan-supercharger stage performance of a turbofan engine. The full-scale fan-supercharger stage performance test device includes inner road 2, Pressure stage 3, outer culvert casing 4, top-cut fan 5, the size of connotation channel 2 is the same as that of the real connotation channel 2 of turbofan engine; supercharging stage 3 is located in connotation channel 2, and the size of supercharging stage 3 is the same as The size of the real supercharging stage of the turbofan engine is the same; the size of the outer casing 4 is smaller than the size of the real outer casing of the turbofan engine, so that the bypass ratio of the test device is smaller than the real bypass ratio of the...
