摘要

摘要: 泵喷推进器由于导管的存在, 使其声场的产生与传播较螺旋桨有很大不同。为掌握该推进器的声学性能,指导推进器的声学优化设计, 文中结合点源模型和边界元方法完成了泵喷推进器导管内转子的声场预报, 分析了导管对转子声场的影响。对导管内转子声场而言, 其声场特性与螺旋桨有相似之处, 宽带声源级指向性呈8字形。由于导管散射效应的存在, 转子的入射声场与散射声场存在较大差异, 使得导管对径向测点处转子声场影响较大, 对轴向测点处转子声场的影响可以忽略。

Abstract: The sound field generation and propagation of a pump-jet propulsor is quite different from that of a propeller because of the existence of the duct. In order to understand the sound performance of the pump-jet propulsor for its acoustic optimization design, the point source model and boundary element method are used to forecast the sound field of rotor in the duct, and the effect of the duct on the sound field is analyzed. The characteristic of rotor sound field in the duct is similar to that of the propeller, and the directivity of wide-band acoustic source level shows 8 shape. The incident sound field and scattering sound field of the rotor are quite different due to the scattering effect of the duct, resulting a remarkable effect of the duct on the sound field of the rotor in radial direction, and a neglectable effect in axial direction.
