Abstract
Controllable pitch propeller(CPP) system for marine that moved the blade pitch angle without reversing revolution of the propulsion shaft has been used for the ship of special purpose, as battle warship, icebreaker, excursion ship, deep-see fishing vessel, by reason of the efficient load control, improvement of ship control and so on. But almost of the CPP system has depended on import and some has been used for the introduction manufacturing of technology from the affiliated company what avoid the transferring technology. So, it is difficult to learn the main technology. Because of this situations, the study of stress and vibration for CPP doesn't widely pursue.

This thesis is focused on the stress and vibration characteristics of the CPP blade by finite element method(FEM) using ANSYS code and design of the CPP system. First of all, to compare the stress shape of the blade and maximum stress point of the blade section at root in ahead and astern condition, equivalent stress is solved about CPP blade and around root that is maximum stress area. Also, through the vibration analysis, deformation characteristics of the CPP blade of each mode are solved and the results show the frequency zone of occurring maximum displacement.
