摘要

翼尖涡是客机尾涡的重要组成部分，不仅会产生诱导阻力影响飞机的经济性，同时还会带来尾迹遭遇问题进而影响到后续飞机的安全性。随着数值模拟和实验技术的提升，对翼尖涡结构特征、动力学特征、不稳定性发展、演变规律等现象和机理的认知不断加深，并取得了丰富的研究成果。近些年，随着不稳定性理论和模态解析方法的发展，研究者针对翼尖涡的不稳定性及其模态特征开展研究，试图揭示翼尖涡不稳定性演变的规律及机制，并期望能建立一种基于不稳定性的流动策略，从而实现对翼尖涡失稳衰减的最优化控制。本文对飞机翼尖涡不稳定性及其模态特征的研究展开综述，首先介绍翼尖涡的不稳定性特征，然后比较典型模态分析方法的基本原理，进而分析翼尖涡不稳定性及其模态结构特征，最后讨论翼尖涡不稳定性模态分析的研究现状及未来发展趋势。

Abstract

Wingtip vortex is an important part of the civil aircraft wake vortex

which not only induces drag and affects the economy of the aircraft

but also causes the wake encounter problem and affects the safety of the follow-up aircraft. With the advancement in numerical simulation and experimental measurement techniques

the understanding of the wingtip vortex structure characteristics

dynamic characteristics

instability development

evolution and other phenomena and mechanisms have been deepened

and various research results have been obtained. In recent years

with the development of instability theory and modal analysis methods

researchers have studied the instability and modal characteristics of wingtip vortices

trying to reveal the law and mechanism of the instability evolution

with the hope to establish a flow control strategy based on instability to achieve the optimal control to accelerate the attenuation and dissipation of wingtip vortices. This study reviews the research on wingtip vortex instability and its modal characteristics. We firstly introduce the instability characteristics of wingtip vortices

then compare the basic principle of typical modal analysis methods

and then analyze the wingtip vortex instability and its modal structure characteristics. Finally

the research status and future development trend of wingtip vortex instability modal analysis are discussed.
