主要介绍了美国高超声速结构响应和寿命预估能力评估的研究计划。该计划由美国空军研究实验室(AFRL)的结构科学中心(SSC)承担。在计划的第一阶段,对波音公司高超声速技术现状与满足高超飞行器设计分析需求的差距进行了评估。在计划的第二阶段,为能够具体反映目前高超声速结构响应分析和疲劳寿命预估技术面临的挑战,以飞行马赫数5~7的高超声速巡航机(HCV)典型部位壁板为例,利用现有技术对壁板进行详细设计和分析。
This paper mainly introduces the plan of research on the assessment of hypersonic structure response and life expectancy in the United States. The program is carried out by the structural science center (SSC) of the U.S. Air Force Research Laboratory (AFRL). During the first phase of the program, the gap between Boeing’s hypersonic technology status and the need to meet the hypersonic aircraft design analysis was evaluated. In the second phase of the project, in order to concretely reflect the challenges of the current hypersonic structure response analysis and fatigue life prediction technology, taking the typical high-speed hypersonic cruiser (HCV) siding panels with flight maneuvers of 5 to 7 as an example, The prior art details the wallboard design and analysis.
