摘要

在飞机设计中,优化已经成为一种常见的做法,特别是当考虑到结构和空气动力学的相互作用时。通常在工业环境中使用的性能指标包括结构重量、阻力、升阻比、燃料燃烧或最大航程。通常的做法是仅在少数样本点上评估此类性能指标。为了实现真正经济的飞机设计,有必要在多学科结构优化期间包括完全集成的任务分析,因为飞机的飞行行为和实际操作条件之间存在很强的耦合。本文提出了任务分析实现的模块化方法,该方法可以利用各种物理模型及其组合,抵消与完全集成任务分析相关的一些计算需求,并允许将资源集中在需要的地方。

Structural wing optimisation targeting economical mission performance of a passenger aircraft
In an aircraft design, optimisation has become a common practice, especially when structural and aerodynamics interactions are considered. Performance measures often used in an industrial setting include structural weight, drag, lift to drag ratio, fuel burn or maximum range. It is a common practice to evaluate such performance indicators only on a handful of sample points. To achieve a truly economical aircraft design it is necessary to include a fully integrated mission analysis during a multidisciplinary structural optimisation, as there is a strong coupling between a flight behaviour and actual operational conditions of an aircraft. This paper makes a case for a modular approach to a mission analysis implementation that could utilise a variety of physical models and their combinations, offsetting some of the computational demands related to a fully integrated mission analysis and allowing to focus resources where they are needed.
