AI Technical Summary

Technical Problem

In existing wind tunnel tests of elastic models, the pressure measurement devices have insufficient pressure measurement capabilities, especially in the weak areas of the wing, where it is difficult to accurately measure the pressure distribution, which affects the accuracy of the test data. Furthermore, traditional pressure measurement methods affect the model stiffness and are complex to install.

Method used

The pressure measuring rib and adapter are manufactured using 3D printing technology. The pressure measuring holes are integrally formed, and the connection holes and channels are precisely designed. The pressure measuring function is realized through the tubeless pressure measuring rib and adapter. The pressure measuring holes have high verticality and flexible arrangement range, reducing the impact on the model's stiffness.

Benefits of technology

It improves the accuracy and flexibility of pressure measurement data, reduces installation complexity and material consumption, ensures the validity and reliability of test results, and expands the range of pressure measurement points.

Abstract

This invention provides a pressure measuring device for wind tunnel testing of elastic models, comprising: a pressure measuring rib having multiple pressure measuring holes, multiple pressure measuring channels built into the rib, and multiple connecting holes. Each pressure measuring hole is open on the surface of the rib and extends inward from the surface. The connecting holes are arranged adjacent to each other on the side surface of the rib. Each pressure measuring channel connects a pressure measuring hole and a connecting hole. An adapter has a body and multiple connecting pipes. Multiple air holes are formed in the body, and the air holes are not interconnected. A first end of the body is configured to engage with the side surface of the pressure measuring rib, with the air holes open at the first end. At the second end of the body, each connecting pipe is fixed to an air hole and connected to it. This pressure measuring device can solve the problem of pressure measuring in wind tunnels of elastic models, is highly feasible, and can improve the installation efficiency of wind tunnel models, improve the accuracy of wind tunnel test data, and reduce the consumption of test materials.
