本SAE信息报告的范围仅限于风洞试验，尽管公认道路车辆空气动力学特性的许多方面可以在其他试验设施（如水箱）中进行调查，尤其是在道路上。例如，滑行测试通常用于确定空气动力阻力（单独或作为总阻力的一部分），人工阵风发生器用于调查车辆对横风阵风的敏感性。本报告中还排除了道路车辆的气候风洞试验，第3节对其进行了更详细的定义。该报告涵盖了汽车试验风洞的空气动力学要求，以及所需的设施设备和影响试验车辆或模型的要求。 本文描述的试验方法和程序包括六分力测量以及车辆/模型表面和周围流场上的压力和速度测量。如前所述，本文件是与许多其他SAE信息报告和推荐规程（1-5）一起编制的，其中每一个都提供了比此处给出的更详细的汽车空气动力学测试的特定方面。

The scope of this SAE Information Report is confined to wind-tunnel testing, although it is recognized that many aspects of the aerodynamic characteristics of road vehicles can be investigated in other test facilities (such as water-tanks) or, especially, on the road. For example, coastdown testing is often used to determine aerodynamic drag (either in isolation or as part of the total resistance), and artificial gust generators are used to investigate the sensitivity of vehicles to cross-wind gusts.Also excluded from the present Report are climatic wind-tunnel tests of road vehicles, which are defined in more detail in Section 3.The Report covers the aerodynamic requirements of a wind-tunnel for automotive testing, together with the facility equipment needed and the requirements affecting the test vehicle or model. The test methods and procedures described here include those for six-component force measurements and measurements of pressures and velocities both on the vehicle/model surface and the surrounding flow-field.As already indicated, this document has been prepared in conjunction with a number of other SAE Information Reports and Recommended Practices (1-5), each of which provides greater detail than is given here on its particular aspect of automotive aerodynamic testing.
