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.

航空航天业正处于一个转折点：环境问题、法律框架和新能源意味着该行业需要探索复合材料飞机配置的不同结构设计空间。然而，使用过去工业所遵循的较慢的实验式设计金字塔，这并不容易实现。上述情况为超大型综合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案例，但这个问题是难以解决的。我的愿景是，大型复合结构的结构设计可以通过一种新的模拟范式实现：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），以及智能算法在后端（HPC集群）工作的地方，从超过1tb的输出数据库中提取高价值数据，因为它们正在构建。这种模式将使大型综合复合材料结构的数值设计成为可能，从而对急需的新飞机结构的出现产生重大影响。
