翼型对水下滑翔机滑翔性能影响分析

摘要/Abstract

摘要： 选用NACA 4位数翼型，采用计算流体力学方法分析了翼型对水下滑翔机滑翔经济性和稳定性的影响。研究结果表明，合适的翼型可以极大地提高滑翔经济性，但对滑翔机静稳定性的提高并不明显；对于非对称翼型，翼型的弯曲程度和弯曲方向对滑翔经济性和静稳定性的影响均很大。在此基础上，并结合工程实际，提出了变后缘柔性机翼方案，通过数值模拟试验验证了所提出方案的可行性。研究成果为水下滑翔机柔性机翼的设计提供了理论参考。

Abstract: Based on the NACA 4-digit airfoil, effects of the airfoil on flight performance, such as flight efficiency and static stability, were analyzed by using the method of computational fluid dynamics with the environment of commercial software ANSYS-FLUENT. Results show that appropriate airfoil may greatly improve the flight efficiency of AUGs, but the improvements to the static stability of the AUGs are not so obvious. For asymmetric airfoils, the camber and bending directions of the airfoil have great influences on both of flight efficiency and static stability. According to the present researches and combining with the engineering practices, the flexible wings with variable trailing edge were proposed to make the AUG get better flight performance, which was proved by the numerical simulation experiments. The present achievements provide theoretical guidance for the design of flexible wings of AUGs.

Key words: autonomous underwater glider(AUG), airfoil, flight efficiency, flight stability；flexible wings with variable trailing edge
