摘要

本文提出了一种解释翼型气动现象的新理论。该理论基于牛顿经典力学的应用，而不是流体动力学的微分方程。开发方程的方法包含物体在流体中运动的几何和流体动力学观点。基于该理论，可以通过在升力产生的几何结构中应用“收缩”和随后的“膨胀”来产生新的翼型设计。在升力和阻力的背景下，翼型厚度的影响是重要的，并对其对翼型空气动力学的影响进行了进一步的研究。报告并讨论了获得的结果。

A theory on understanding aerodynamic phenomena of airfoils and the significance of airfoil’s thickness on lift and drag

This paper proposes a new theory explaining aerodynamic phenomena of airfoils. The theory is based on the application of Newton’s classical mechanics rather than differential equations of fluid dynamics. The approach in developing the equations contains both geometrical and fluid dynamics perspectives of motion of body in a fluid. Based on the theory, it is shown that new airfoil designs could be generated through the application of “contraction” and subsequent “expansion” in the geometry for lift generation. The effect of thickness of airfoil is important in the context of lift and drag and further investigation on its effect on airfoil aerodynamics is conducted. The obtained results are reported and discussed.
