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...

Abstract

The invention discloses a full-scale fan-booster stage performance test device and test method, the full-scale fan-booster stage performance test device comprises an inner duct, a booster stage, an outer duct casing and a topped fan, and the size of the inner duct is the same as the size of a real inner duct of a turbofan engine; the size of the supercharging stage is the same as that of a real supercharging stage of the turbofan engine; the size of the outer culvert casing is smaller than the size of a real outer culvert casing of the turbofan engine, so that the bypass ratio of the testing device is smaller than the real bypass ratio of the turbofan engine. And the top of the top cutting fan is matched with the outer culvert casing. The size of the inner duct and the size of the booster stage of the test device are the same as the size of a real part of the turbofan engine, and the duct ratio of the test device is smaller than the real duct ratio of the turbofan engine by reducing the size of the outer duct casing, so that the input power required by the test is greatly reduced, and errors caused by correction from a reduced scale to a full scale are avoided.

Description

technical field [0001] The application belongs to the field of aero-engine testing, and in particular relates to a full-scale fan-supercharger stage performance testing device. Background technique [0002] The fan-supercharger stage is one of the important parts of the turbofan engine, and the matching of the aerodynamic design between the fan and the supercharger stage directly affects the overall performance of the fan-supercharger stage components. In order to verify the matching characteristics of the fan and the booster stage, a fan-booster stage performance test is required. The bypass ratio of an advanced civil aircraft turbofan engine is as high as about 10, that is, the flow rate of the fan is very large, which consumes a lot of power. If a full-scale fan-supercharger stage performance test is performed directly (that is, the size of the fan and the supercharger stage are the same as the real size), extremely high power input is required, and the feasibility of th...
