鱼类身体的波状动运,是一种能将阻力和推力以最合理的结合统一于一个系统的高效推进方式,本文在分析研究鱼类游泳动作的基础上,探讨了应用常用机构设计仿鱼推进装置的方法。
It's well known today that the propulsion for most ships is usually accomplished by rotating propellers attached to the end of a streamlined bo- dy,and about 90% of the propulsion has been wasted for overcoming the drag which originated from high-energy stern wake.But for fish,the high energy wake is practically eliminated.Besides reducing drag by a more streamlined shape and a better surface,its mystery mainly lies in moving by the entire body which could wipe the wake away by being thrown laterally into a propulsive wave.In this paper,based on the study of the fish-swimming, the writers have presented two underwater propelling mechanisms which can imitate the fish swimming motion.
