摘要
用基于速度势的低阶面元法建立预估导管螺旋桨定常性能的计算方法,即对导管和螺旋桨都采用面元法,在计算面元的影响系数时计入导管和螺旋桨的相互影响。将对JD简易导管桨的计算与实验结果进行比较表明,该方法可以有效地应用于导管桨的定常性能计算。
A simple numerical method is presented for predicting the steady performance of ducted controllable pitch propellers, in which a potential based surface-panel method is applied both for the propeller and duct. The hydrodynamic interaction between the propeller and the duct is solved in calculating influence coefficients. Nurnerical calculations are carried out for JD simplified ducted propeller series. The numerical results are compared with experimental data and good agreement is obtained.
