Abstract: A new type of liquid propeller—single-blade propeller is discovered and its dynamic equations are established by means of kinematic analysis of the blade and loads applied on the blade. The prototype of the single-blade propeller based on the ADAMS using the derived equations is constructed so that the dynamic analysis and simulation of the system can be done automatically. The results from dynamic simulation of the new propeller demonstrate that it can run smoothly at desired speed, and the effective propelling force from the blade changes in the form of pulse wave in magnitude, but its peak and frequency keep constant under even rotation.
