协作优化在无人机概念设计中的应用

多学科设计优化（MDO）是当前飞行器设计研究中一个最新、最活跃的领域，而协作优化是解决多学科设计优化问题的一种二级MDO算法。将协作优化应用到无人机的概念设计中，建立了包含气动、重量、性能和稳定性四个学科的无人机系统优化模型。与传统的设计方法相比，该方法为无人机在概念设计阶段提供了更加合理的飞行器外形，降低了初步设计和详细设计阶段对飞行器外形修改的可能性，从而缩短研制周期和降低成本。

Application of Collaborative Optimization to the Conceoptual Design of UAV

Multidisciplinary design optimization has been a focus in aircraft design. One bi- level MDO method is the collaborative optimization. This paper describes the integration of aerodynamics, weights, performance and stability in a UAV conceptual design using a collaborative optimization method. This provides the freedom of configuration change at an early conceptual stage, which reduces the risk of configuration change at preliminary design and detailed design and development cycle and cost.
