摘要

风洞是进行车辆、飞机等原型机气动试验最常用的系统，以防止工程失败。在这类系统中，动态压力测量一直是一个挑战。为此，本文提出开发一种全嵌入式智能系统控制的风洞，以实现动态压力测量。采用基于可编程控制器S7-1500的控制系统对空气流速进行测量和控制，并用试验段内的Annubar装置对平均流速进行测量。本系统采集的数据存储在基于SQL Server Express的数据库中，便于实时监控和历史分析。

Wind Tunnel Assembly for dynamic pressure characterization

The wind tunnel is the most used system to make the aerodynamic test of prototype like vehicles and airplanes, in order to prevent project failures. In particular the dynamic pressure measurement has been a challenge in this type of systems. In this sense, the present work proposed the development of a wind tunnel all controlled by embedded smart system in order to make the dynamic pressure measurement. The air flow rate is measured and controlled by a controller system based on Programable Logic Controller S7-1500 and the average velocity was measured with the Annubar device inside the test section. The data collected from this system is stored in a Database based on SQL Server Express, for real time monitoring and historical analysis.
