摘　　要：针对水面舰船的高、低航速多工况服役需求,通过增强桨叶剖面在低空泡数条件下的负荷和控制桨叶剖面在高空泡数条件下的流动分离,提出了一种螺旋桨叶剖面参数化构型。在此基础上建立了多工况叶剖面优化设计方法,使舰船螺旋桨在高、低航速下均能有效、经济航行。以DTMB 5415舰船螺旋桨为例,优化设计了一个叶剖面,并应用到桨叶设计。通过与常规NACA剖面桨在多工况下的对比模型试验获得验证,试验结果表明:对应20 kn航速时,两种剖面螺旋桨的水动力效率相差1.5%;在对应40 kn航速工况下优化剖面桨水动力效率比NACA剖面桨高6.4%,并避免了推力突降风险。In order to satisfy requirements of surface naval ships under high and low speed conditions,a parametric model of propeller's blade section is put forward,in which load on the blade section is augmented under low cavitation number condition,and flow separation on blade section is controlled under high cavitation number condition.Taking the DTMB5415 navy ship as an example,propeller's blade section is optimized and applied to blade design.Model tests show that hydrodynamic efficiency of the propeller with optimized section is 1.5%20 knots,and 6.4%greater than that with NACA section at the speed of 40 knots,as well as risk of the breakdown in thrust can be avoided.
