Development and Research of Sleeve Mounted Propeller

Abstract

The development of Sleeve Mounted Propeller have been proceeded to improve on fitting method of conventional propeller. This improved system, propeller secured on shaft with sleeve, has characteristics as follows;
(1) Based facing up of propeller as the propeller can be faced up with the sleeve instead of the propeller shaft.
(2) Simplified machining of the propeller shaft so as to get along without the tapered and screwed end.
To prove the reliability, a model propeller was prepared and tested. As a result, the system was confirmed to be reliable and a great number of information for the design was obtained.
