许多鸟类和蝙蝠以及它们的机器人对应物的飞行发生在从 1 × 104 到 1.5 × 105 的基于弦的雷诺数范围内。正是在这个范围内，简单、刚性、固定机翼的空气动力学对几何形状和环境的微小变化变得异常敏感，从而产生两种后果。首先，这种规模的实用起重装置可能不是简单、刚性的固定翼。第二个是，当任何一个都可能出错时，对实验和计算进行基线比较就变得非常重要。在这里，我们研究了 NACA 0012 翼型的一个表面上简单的案例，并对技术文献、新实验和计算进行了仔细比较。协议（或缺乏协议）将建立一个或多个基线结果以及围绕它们的一些敏感性。这个想法是，诊断程序将有助于指导后续更复杂病例的比较和预测。
The flight of many birds and bats, and their robotic counterparts, occurs over a range of chord-based Reynolds numbers from 1 × 104 to 1.5 × 105. It is precisely over this range where the aerodynamics of simple, rigid, fixed wings becomes extraordinarily sensitive to small changes in geometry and the environment, with two sets of consequences. The first is that practical lifting devices at this scale will likely not be simple, rigid, fixed wings. The second is that it becomes non-trivial to make baseline comparisons for experiment and computation, when either one can be wrong. Here we examine one ostensibly simple case of the NACA 0012 aerofoil and make careful comparison between the technical literature, and new experiments and computations. The agreement (or lack thereof) will establish one or more baseline results and some sensitivities around them. The idea is that the diagnostic procedures will help to guide comparisons and predictions in subsequent more complex cases.
