摘要
针对高超声速进气道 V 形溢流口处极易形成复杂激波干扰,并产生严酷气动热/力载荷的问题,本文梳理和总结了近年来提炼模化出的 V 形钝化前缘(VBLE)及其相关研究的进展情况.回顾了 V 形钝化前缘模型的提出过程,介绍了其几何及流动的主要特点,分析了 V 形钝化前缘的激波干扰类型、气动热/力载荷以及激波振荡特性,探讨了降低局部极高气动热/力载荷及抑制激波振荡的优化设计方案,并对未来的研究方向进行了展望,以期促进对 V 形钝化前缘激波干扰现象的深入理解.
Abstract
A V-shaped cowl lip is commonly designed for flow spillage in hypersonic inward-turning inlets,which leads to complex flow structures and severe aerothermal/pressure load.A number of investigations has been performed to understand the shock interactions and underlying mechanisms,since a generic V-shaped Blunt Leading Edge(VBLE)was proposed.The types of the shock interactions,characteristics of aerothermal/pressure load,unsteady shock oscillations,and aerodynamic optimization of the VBLE were reviewed,after a retrospection of the naissance of the VBLE.Finally,future work was discussed to improve knowledge of the VBLE to a new horizon.
