基于曲面的飞机机翼结构参数化设计

以某型无人机机翼结构设计为例，介绍在计算机辅助三维交互应用（Computer Aided Three-dimensional Interactive Application，CATIA）软件三维设计环境下，基于机翼理论外形曲面的机翼结构参数化设计方法。通过完整数据链的全相关结构设计，实现设计更改过程的全模型自动更新，设计周期缩短，成本降低。

Parameterized aerofoil structure design based on surface

Given an example of aerofoil structure design of a certain type of pilotless aircraft, a parameterized aerofoil structure designing method is introduced, which is based on the surface of aerofoil theoretical configuration under the Computer Aided Three-dimensional Interactive Application (CATIA) 3D software designing environment. By using whole correlative design of integrated data chain structure, automatic updating of whole-model in the designing procedure is realized with the designing period shortened and designing cost reduced. It has actual referring value for the progression of digitalized structure-design and production in the aero industry.
