The aerospace industry is at a turning point: environmental concerns, legal frameworks and new energy sources mean that the industry needs to explore a different structural design space for composite aircraft configurations. Yet this is not readily possible using the slower experimentally-heavy design pyramid followed by industry in the past. The above scenario makes a compelling case for numerical structural design of very large integrated composite aircraft structures, but this problem is intractable. My vision is that structural design of very large composite structures can be enabled by a new simulation paradigm: I propose that, during the analysis, CAE models of very large structures adapt in real-time the scale of idealisation as required (adaptive multiscale), adapt in real-time the configuration of the structure (adaptive configuration), and where intelligent algorithms work at the back-end (HPC cluster) to extract high-value data from over 1 Tb output databases as they are being built. This paradigm will enable numerical design of very large integrated composite structures, thus having a significant impact on the emergence of much-needed new aircraft configurations.

航空航天工业正处于一个转折点：环境问题、法律的框架和新能源意味着该行业需要为复合材料飞机构型探索一个不同的结构设计空间。然而，这是不容易的，使用缓慢的实验重设计金字塔其次是工业在过去。上述方案为超大型一体化复合材料飞机结构的数值结构设计提供了一个令人信服的例子，但这个问题是难以解决的。我的愿景是，非常大的复合材料结构的结构设计可以通过一种新的模拟范式来实现：我建议，在分析过程中，非常大的结构的CAE模型根据需要实时适应理想化的规模（自适应多尺度），实时适应结构的配置（自适应配置），智能算法在后端（HPC集群）工作，在构建时从超过1 TB的输出数据库中提取高价值数据。这种模式将使非常大的综合复合材料结构的数值设计，从而对急需的新飞机构型的出现产生重大影响。
