摘要: 基于叶素动量理论、升力线及面元法等的涵道螺旋桨桨叶设计方法,由于方法本身存在诸多简化,故设计结果一般同真实性能存在一定偏差。而基于更为准确的CFD求解方法所进行的设计及优化设计等,由于需进行大量CFD计算,设计效率偏低。因此,为使设计具备快速性的同时也具备较高的准确性,基于叶素动量理论,通过CFD计算对设计进行修正,提出一种涵道螺旋桨桨叶高效设计方法。在设计过程中通过对入流角及迎角进行修正,提高了设计的精度,而修正系数通过CFD结果反解得到。初步设计后,经过修正系数求解、再设计进行迭代,可快速得到满足设计需求的涵道螺旋桨。对不同状态涵道螺旋桨的设计表明,该设计方法基本进行2次CFD计算与再设计便可满足设计要求,设计高效的同时具有较好的设计精度。

Abstract: The ducted propeller designed with the methods based on blade element momentum theory, lift line and panel method has a certain deviation from the real performance due to simplification of the methods. The design and optimization design based on the more accurate CFD method needs a lot of CFD calculation, so the design efficiency is low. To improve the efficiency and accuracy of the design, a design method is proposed based on the blade element momentum theory and CFD modification. The accuracy of the design is improved by modifying the inflow angle and angle of attack, and the reasonable correction coefficient can be obtained by inversely solving the CFD calculation results. After the preliminary design, the ducted propeller which meets the design requirements can be quickly obtained by iterative design that consists of solving the correction coefficient and redesigning. The design of ducted propellers in different states shows that the design method can basically meet the design requirements by two iterations of CFD modification and redesign. The design is efficient and has good design accuracy.
