针对艇用小型喷水推进装置，采用模块化产品的设计思路，从需求分析入手，初步形成满足设计要求的喷水推进模块总体方案。基于功能分解，将喷水推进模块划分为多个子功能模块，依据模块单元的功能属性和输入/输出开展结构与接口的详细设计，并注重模块的独立性和通用性设计。最后根据建立的评价体系，对功能、模块化和标准化等指标进行评价。基于本文思路设计的喷水推进装置应用于13 m工作艇并取得了良好的实船试航效果。装置的模块化程度高、安装维护便捷，对小型喷水推进装置的模块化设计有一定借鉴意义。
For small waterjet-unit, introduce the design process of the modular product, start with demand analysis and form the general design proposal of the waterjet module satisfied customer's requirements. Basis on the functional decomposition theory, divide the module into several sub-functional modules and carry out the detail design according to the properties and input/output of each sub-modules. In this stage the detail design will emphasize the independent and universal character of the modules. Finally evaluate the values of the functionality, modularization and standardization of the modules with the evaluation system established before. The waterjet-unit designed by using the method described in this paper was applied to a 13 m work boat which had achieved excellent performance in the shipping trial experiment. The unit has features of high integration level and convenient installation and maintenance,and has certain reference for future works on the small waterjet-unit.
