摘要
为寻找高效、可靠的吊舱推进器分析手段,研究了迭代面元法和非定常整体面元法求解公式.在此基础上针对吊舱推进器的结构特点,提出将吊舱体和螺旋桨作为整体求解的定常面元法.随后运用这3种面元法计算了某一吊舱推进器,并对计算结果的精度和计算耗时进行对比.结果表明,迭代面元法、非定常整体面元法和定常整体面元法计算精度相差不大,与试验值相比,计算结果的相对误差均控制在5%以内,但定常整体求解方法计算时间最少.通过对定常整体求解面元法公式推导表明,该方法能够适用于其他由螺旋桨和固定构件组成的组合推进器.
The paper is devoted to developing an efficient method for the performance prediction of podded propulsion.The iterative surface panel method which treats the pod and propeller as two separate parts and the unsteady integral surface panel method which treats the pod and propeller as a whole were discussed.Based on these studies and the analysis of podded propulsion geometry,an integral steady surface panel method which treated the pod and propeller as a whole was presented.Then,apodded propulsion was analyzed by these three surface panel methods.Besides,the calculation results and computation time were compared.Numerical results show that these surface panel methods have similar accuracy,and the relative errors are within 5% compared to experimental data.But the computation time of integral steady surface panel method is much less than the other two surface panel methods.Based on the discussion of integral steady surface panel method,it can be concluded that the method could be applied in the analysis of other combined propulsors which consist of a propeller and a fixed component.
