摘　　要：[背景]新一代先进战斗机的研制更加强调高机动性、高敏捷性,要求飞行器具有良好的大迎角过失速机动能力,需要掌握复杂机动过程伴随的飞行器机体的大面积流动非对称性/分离、旋涡破裂、多涡系结构等复杂现象和规律,这对风洞复杂动态试验能力提出了高的要求.绳牵引并联支撑是基于机器人技术的一种新型机构,具有刚度较大,动态性能良好等优点,为风洞试验提供了一种新的手段.[进展]本文首先简要论述已有基于传统硬式支撑方式的动态风洞试验能力;然后针对新型的绳牵引并联支撑,分析国外在风洞试验中的应用研究现状,并通过梳理关键技术问题,重点阐述本研究团队近年来在组合动导数、大迎角、旋转弹箭、多自由度耦合等复杂动态气动力风洞试验研究中取得的相关进展.[展望]最后指出绳牵引并联支撑可以通过加强布局优化设计和智能化控制,进一步提高支撑系统的综合性能;并结合流场测量等手段,进一步提升其在风洞动态试验中的能力.上述总结与分析可为绳牵引并联支撑技术在风洞试验中的工程应用提供一定的理论指导与技术支撑.[Background]The development of the next generation of advanced fighter aircraft places a great emphasis on high maneuverability and agility.This emphasis requires that aircrafts must secure excellent post-stall maneuvering capabilities at high angles of attack(AoAs).It is necessary to understand the complex phenomena and patterns associated with large-scale asymmetric flow/separation,vortex breakdown,and multi-vortex structures during high-angle-of-attack maneuvers.This necessity places high demands on the capability of wind tunnels to conduct complex dynamic tests.Herein,we propose that wire-driven parallel suspension,a new mechanism based on robotic technology,offers advantages such as high stiffness and good dynamic performance,providing a new means for wind tunnel testing.[Progress]First,this paper briefly discusses the existing dynamic wind tunnel testing capabilities based on traditional rigid support methods.Then,it analyzes the current state of abroad research and application of wire-driven parallel suspension in wind tunnel tests.By identifying key technical issues,the paper highlights the recent progress made by our research team in complex dynamic wind tunnel tests,particularly with the focus on high angles of attack and multi-degree-of-freedom coupling.[Perspective]Finally,we propose that the comprehensive performance of the wire-driven parallel suspension system can be further improved through strengthened layout optimization design and intelligent control.Additionally,by integrating methods such as flow field measurement,its capabilities in wind tunnel dynamic testing can be further enhanced.Hopefully,the summary and the analysis proposed herein can offer theoretical guidance and technical support for the engineering application of wire-driven parallel suspension technology in wind tunnel tests.
