等厚薄板翼型的气动力特性研究

A STUDY CONCERNING AERODYNAMIC FEATUERS OF THIN CAMBERED PLATE AIRFOILS

本文从吹风实验及数据分析两方面来研究等厚薄板翼型的气动力特性。在实验中对单园弧、双圆弧、抛物线三种类型的薄板翼型进行了孤立翼型的吹风试验，得出了各翼型升力系数，阻力系数随冲角变化的结果。然后利用非交错网格下的ＳＩＭＰＬＥ方法，计算了等厚薄板翼型流场，计算结果和实验结果吻合较好。

The aerodynamic features of thin cambered plate airfoils are studied numerically and experimentally in this paper. In the experimental study, the three types of isolated plate airfoils of circular arc, double-circular arc and parabola section are tested in wind tunnel.The variations of lift coefficient and drag coefficient with the incidence are presented in detail.In the numerical study, the SIMPLE method along with the non-stagged grid arrangement are adopted for predicting the turbulent flow over the isolated airfoils. The numerical results agree quite well with the experimental data.
