In order to enhance the flexible characteristics of structure and motion in bionic propeller, the paper designs a bionic undulating propeller with a pump-valve controlled hydraulic system, called HBUP (Hydraulic Driven Bionic Undulating Propeller).
The HBUP could produce variable wave length under different connection method between RDV and BSUs.
In figure 3, P is a common point on bionic fin [OMEGA] in HBUP Frame [O.
