摘　　要：针对船舶推进领域"喷水推进"与"泵喷推进"两概念混淆的现状,本文从两者的起源及发展历程出发,在系统分析两者结构型式的基础上,根据流体力学控制体原理及喷水推进泵理论剖析了两者的水动力原理及核心部件的做功机理。针对控制体的外流场问题,运用翼型升力理论及叶片泵理论推导演绎了外置式喷水推进与泵喷推进外流场对推进系统总推力的作用,阐明了两者原理相同、核心功能转化部件均为喷水推进泵,论证了泵喷推进为喷水推进在水下航行体领域应用时的特定称谓,是喷水推进技术在水下航行体领域的发展。In order to clarify the confusion between the concepts of waterjet propulsion and pumpjet propulsion,starting from the origin and development process of the two concepts,control volume principal of fluid mechanics and waterjet pump theory were applied in this paper to analyze the hydrodynamic principles and work mechanism of the core components on the basis of systematically analysis of the structural forms of the two concepts.Aiming at the problem of external flow field outside the control volume,airfoil lift theory and vane pump theory were used to deduce the effect of external flow field on the total thrust of outboard waterjet propulsion and pumpjet.It is clarified that the core energy conversion components of them is waterjet pump which indicates the identical working principle for the two concepts.It is demonstrated that pumpjet is a special term for the application of waterjet propulsion in the field of underwater vehicles,and it is a development of waterjet propulsion techniques in the field of underwater vehicles.
