摘要
热-结构试验是高超声速飞行器研制过程中不可或缺的环节.本文在给出热-结构试验内涵与特征的基础上,结合热-结构试验典型科目介绍,呈现了热-结构试验体系总体架构,为全面了解热-结构试验提供参考;其次重点分析了当前热-结构试验中亟待突破的时变超高温热载实现、局部热载大梯度模拟以及时/频域载荷协同等 7 大关键技术.
Abstract
Thermal-structural test is an indispensable verification step in the development of hypersonic vehicle.Based on the connotation and characteristics of thermal-structural test,combined with an introduction to some typical subjects of thermal-structural test,this article presents the overall architecture of the thermal-structural test system,providing a reference for a comprehensive understanding of thermal-structural test;Secondly,it focuses on the analysis of seven key technologies urgently needed to be breakthrough in current thermal-structural test,including the realization of time-varying ultra-high temperature thermal loads,large gradient simulation of local thermal load,and time/frequency domain load coordination.
