Description

Technical Field

[0001] The present application belongs to the field of installation and positioning of pneumatic probes for compressor interstage testing in aircraft engines, and specifically relates to an installation and positioning device for a pneumatic probe for compressor interstage testing and a method thereof. Background Art

[0002] The compressor is an important component of an aircraft engine, and its performance is related to whether the aircraft engine can operate efficiently and stably.

[0003] During the compressor development process, in order to meet the needs of inter-stage flow field data for flow field diagnosis and performance analysis, pneumatic probes are usually used to carry out inter-stage flow field tests.

[0004] When conducting the compressor interstage flow field test, the pneumatic probe 1 is first installed on the rotating machinery test equipment 2, and then the rotating machinery test equipment 2 is installed on the compressor 3 casing through a pin. The head of the pneumatic probe 1 is inserted into the interstage flow field through the measuring hole on the compressor 3 casing. Figure 1 As shown, the rotating machinery testing equipment 2 can drive the pneumatic probe 1 to rotate to adjust the angle of the head of the pneumatic probe 1 in the interstage flow field, and can drive the pneumatic probe 1 to move radially along the compressor 2 to adjust the depth of the head of the pneumatic probe 1 in the interstage flow field to install and position the pneumatic probe 1.

[0005] High-precision positioning of the head of the pneumatic probe 1 in the interstage flow field is the basis for ensuring the accuracy of the test of the compressor interstage flow field. However, at present, there is a lack of devices for achieving high-precision installation and positioning of the head of the pneumatic probe 1. Most of the adjustments are made manually, which is time-consuming and labor-intensive, and cannot be visually inspected, making it difficult to ensure high-precision positioning of the head of the pneumatic probe 1 in the interstage flow field.

[0006] This application is proposed in view of the above-mentioned technical defects.

[0040] The following is combined with Figures 1 to 5 This application is described in further detail.

[0041] On the one hand, a pneumatic probe installation and positioning device for compressor interstage testing is provided, such as Figure 2 Shown, including:

[0044] The adapter positioning block 4 has a horizontal surface, a first adjustment surface perpendicular to the horizontal surface, a vertical surface perpendicular to the horizontal surface, and a second adjustment surface perpendicular to the vertical surface, as well as a first visual inspection surface and a second visual inspection surface perpendicular to the horizontal surface and the vertical surface, wherein the first visual inspection surface and the second visual inspection surface have through-going visual inspection holes; the horizontal surface has a compressor casing simulation measurement hole and a compressor casing simulation pin hole; the rotating machinery test equipment 2 is connected to the horizontal surface by a pin, where the pin is fitted in the compressor casing simulation pin hole; the head of the pneumatic probe 1 extends into the visual inspection hole through the compressor casing simulation measurement hole;

[0046] A first height adjuster 6, connected to the first adjustment surface;

[0047] a second level measuring ruler 7, connected to the first visual inspection surface, perpendicular to the horizontal plane and the first adjustment surface;

[0048] The second height adjuster 8 is connected to the second adjustment surface.

[0049] Regarding the installation and positioning device for the pneumatic probe for the compressor interstage test disclosed in the above embodiment, those skilled in the art will understand that the simulated measuring holes and the simulated pin holes of the compressor casing on the horizontal surface of the adapter positioning block 4 are simulations of the measuring holes and the pin holes on the actual compressor 3 casing, and actually restore the measuring holes and the pin holes on the compressor 3 casing.

[0051] Separating the rotating machinery testing device 2 from the horizontal plane;

[0052] The rotating machinery test equipment 2 is connected to the casing of the compressor 3 by a pin. The pin is fitted into the pin hole of the casing of the compressor 3. The head of the pneumatic probe 1 extends into the interstage flow field through the measuring hole on the casing of the compressor 3, so that the head of the pneumatic probe 1 can be quickly and accurately positioned in the interstage flow field, thereby ensuring the accuracy of the measurement of the interstage flow field parameters.

The angle positioning block 10 is used to calibrate the pneumatic probe 1 in a standard wind tunnel, find the aerodynamic center of the pneumatic probe 1, and use the angle positioning block 10 to position it. When the actual compressor 3-stage inter-flow field test is performed, the probe positioned by the angle positioning block 10 is used for measurement to ensure that the actual test aerodynamic center of the compressor 3 is consistent with the aerodynamic center of the wind tunnel calibration pneumatic probe 1.
