The role of pressure scanners in the engine wind tunnel exit test is so great

In the fields of automotive engineering, wind tunnel experiments are the core means of simulating aerodynamic characteristics under real flight or driving conditions. As the key area of the test, the flow field state of the wind tunnel exit directly affects the integrity and reliability of the experimental data. The accurate measurement of its pressure distribution, flow velocity and flow direction is irreplaceable for optimizing the design of aircraft or vehicles, improving performance and safety value. In this process, pressure scanners and Five-Hole Probe, electric displacement mechanism and motion controller are used in cooperation to build the core data acquisition system in wind tunnel exit test.

As an important part of high-precision fluid measurement and control, pressure scanners can realize multi-point, fast and continuous pressure collection in wind tunnel exit testing. Taking WindtunerEthernet Intelligent Pressure Scanners as an example, it integrates high-sensitivity sensors and advanced signal processing technology, with a full-scale accuracy of ± 0.05% FS, and cooperates with high and low temperature compensation algorithms to effectively suppress temperature drift and noise interference. This level is in the advanced ranks in the world and is crucial for capturing small pressure fluctuations in the outlet flow field. At the same time, the built-in automatic calibration and automatic purging functions of Windtuner products can ensure the stability and consistency of data in complex experiments, ensuring that researchers can obtain reliable experimental basis.

Five-Hole Probe is the core tool for velocity and direction measurement in wind tunnel tests. Combined with pressure scanners, Five-Hole Probe can accurately reflect the flow velocity distribution and flow direction on the outlet cross section, thereby providing researchers with comprehensive flow field structure information. Through the precise drive of the electric displacement mechanism and motion controller, the Five-Hole Probe can perform fully automatic scanning within the cross-section range, which not only significantly improves the experimental efficiency, but also eliminates the deviation caused by manual operation, ensuring the repeatability of test results and comparability. The intelligent algorithm of the motion controller supports flexible scanning speed and path, enabling it to meet different experimental scenarios and data acquisition requirements.

This complete set of systems built with pressure scanners, Five-Hole Probe, electric displacement mechanism and motion controller demonstrates excellent comprehensive advantages. It not only realizes high-precision and high-efficiency data collection, but also ensures the stability and traceability of data through intelligent calibration and automatic operation, which greatly improves the scientific and practical value of wind tunnel exit testing.

With its deep accumulation in the field of flow field measurement and control, Windtuner Technology organically combines Ethernet Intelligent Pressure Scanners with self-developed Five-Hole Probe, calibration system and motion control technology to create a complete service covering "detection-acquisition-calibration-analysis" plan. This not only improves the experimental efficiency and data accuracy, but also provides all-round technical support for scientific researchers, helping industries such as automotive engineering to continuously break through key technical bottlenecks, and promoting the improvement of the overall scientific research level and industrial development.
