摘 要 风洞实验室是利用物体运动相对性这一原理，以人工的方式产生并且控制气流，用来模拟飞行器或实体周围气体的流动情况，并可量度气流对实体的作用效果以及观察物理现象的一种管道状实验设备，它是进行空气动力实验最常用、最有效的工具。 中国在风洞领域已经有着许多世界领先的技术，并建成了性能优越的风洞实验室，这些风洞实验室在我国空气动力学相关领域的研究中起到了举足轻重的作用。 本文的主题就是对小型风洞及控制系统的设计、制作、与调试过程进行详细的描述，其中包括了系统方案论证、硬件系统的设计、软件的设计以及整个系统的调试过程等内容，通过这一系列过程，将会增强我对风洞相关知识的了解，同时也对我自己的专业知识水平进行一次考验，提升我的自学能力以及动手能力。 关键词：风洞系统；设计；制作；调试 Abstract Wind tunnel wind tunnel laboratory, namely in the form of an artificial and airflow control, used to simulate the gas flow situation around aircraft or entity, and can measure the effects of airflow on the real and the observation of physical phenomena of a pipeline experimental equipment, it is the aerodynamic experiments is the most commonly used and effective tool.Because of the wind tunnel with easy control, high repeatability, and can through the simple experiment to obtain more accurate experimental data, and many other advantages, therefore, used widely in many fields.China already has many of the worlds leading technology in the field of wind tunnel, and built the superior performance of wind tunnel laboratory, the wind tunnel laboratory in the study of aerodynamic field in our country has played a pivotal role. The topic of this article is for small wind tunnel and the control system design, production, and the debugging process are described in detail designs, including the system hardware design, software design and debugging of the whole system, through this a series of process, I will enhance understanding of the wind tunnel related knowledge, also learned to my own professional knowledge to a test, so as to improve my ability of self-study.
