摘要

气动、热和结构三学科之间的耦合关系是高速飞行器面临的核心问题之一。文中利用强弱耦合关系简化了气动热结构耦合问题,并基于气动加热、瞬态热传导、热结构、热模态和热颤振的单向耦合关系来分析热弹性问题,建立了气动热结构多学科集成分析平台。针对各子学科耗时问题,文中采用了增广的自适应响应面优化策略完成了气动热结构多学科设计优化,在提高了颤振速度的同时,使升力面结构质量有了一定的降低。关键词:高速飞行器;气动热结构耦合;优化设计;单向耦合分析

Abstract

Aero-thermal-structure coupled influence is one of most important problems that high speed vehicles face. The coupled problem is simplified by relationship among these sub disciplines. Based on unidirectional coupling influence among aerodynamic heating, transient heat transfer, thermal structure, thermal mode and thermal flutter analysis, a multidisciplinary integrated analysis platform was established. Aiming at time-consuming problem involving multi-disciplines, adaptive response surface method was employed to optimize the aerothermal-structure coupled problem. The result indicates the mass of lifting surface structure is reduced under a higher flutter speed. Keywords: high speed vehicles; aero-structure-thermal coupled; optimization design; unidirectional coupling analysis

Key words： high speed vehicles; aero-structure-thermal coupled; optimization design; unidirectional coupling analysis
