航行器部件流体动力外形仿生初探

A Preliminary Bionical Exploration on the Fluid dynamic Shape of Aircraft Components

本文简要地介绍了航行器的两种部件流体动力外形仿生的构造特点和模型实验方法，同时给出了主要的实验结果，其中仿鲨鱼头的细长椭锥在大迎角时的侧力减小为圆锥的２３％，采用波纹壁面相对厚度为１３％的机翼的摩阻比光洁翼面的减少了９％。

Bionical testings for two main aircraft components are reported. It is found that the slender elliptical cone, which imitates the shape of shark′s head, may reduce side force by 23% when compared with a normal cone, and that the wing with corrugated surface (thickness ratio 13%) may reduce friction drag by 9% when compared with a smooth wing.
