| 摘 要： | 二维平板或二维对称薄翼型大攻角绕流升力和阻力系数与攻角之间存在的函数关系一般用数据表格的形式给出。本文根据垂直平板绕流阻力实验数据和对称薄翼型全攻角绕流实验数据，分析得到了平板大攻角绕流总压力及其升力分量和阻力分量系数的近似计算公式。结果表明：平板总压力系数约等于攻角正弦值的2倍；总压力的阻力分量系数约等于攻角正弦值平方的2倍；升力分量系数约为攻角2倍的正弦值。计算结果与两组试验数据具有较好的一致性。 |

| Abstract: | The function relationship between the lift and drag coefficients and the attack angles of flow around a flat or a two-dimensional symmetric thin airfoil was expressed in data tabular form generally.In this paper,the approximate formulas of the total pressure and its lift and drag components of incompressible flow around a flat at high attack angles are obtained by using experimental data of flow around airfoils at high attack angles.The results show that the total pressure coefficient at high attack angles ... |
