| 摘 要： | 开发了一个导管螺旋桨定常水动力性能预报的数值计算方法,其中,螺旋桨和导管均采用定常面元法,通过迭代计算考虑桨和导管的相互影响.该方法也可用于导管调距桨在不同转角时的定常性能预估.对JD7704和19a导管螺旋桨以及JD导管调距桨的计算结果表明,该方法计算精度是令人满意的.

| Abstract: | A numerical method is developed to predict the steady performance of ducted propellers. A potential based panel method is applied both for the propeller and duct.The hydrodynamic interaction between the propeller and the duct is solved by an iterative procedure.This method can also be employed for the steady performance prediction of the ducted controllable pitch propellers at different pitch angles.Numerical calculations are carried out for JD simplified ducted propeller series, 19a ducted propeller series and JD-CPP series with JD duct.The calculated results are compared with experimental data and good agreement is obtained. |
