  • 摘要:   目的  针对国内外喷水推进和泵喷推进的概念缺乏完整定义、外延尚存混淆、产品称谓混乱的现状,  方法  通过对这2种推进器工作原理和具体结构的剖析,进行共性提炼和特性区分,提出喷水推进和泵喷推进的定义,指出它们的共性、特性及区别。  结果  喷水推进和泵喷推进均属泵类推进,都是通过管道内叶轮和导叶的流场匹配设计在喷口产生轴向射流而获得推进作用;喷水推进的第一设计指标是高效率、首要保证快速性,相应的设计结果是喷水推进器;泵喷推进的第一设计指标是低噪声、首要保证声隐身性,相应的设计结果是泵喷推进器。  结论  该定义不仅包含和区分了已问世至今的喷水推进器和泵喷推进器,而且也明示了国外某些泵类推进器命名存在的问题。该定义有助于业内对喷水推进和泵喷推进的认识和区分。
