Many devices are designed to augment thrust and efficiency. Propeller’s blade plays a fundamental role in order to enhance efficiency. In this paper, DTMB4382 is selected as reference propeller in which blade reformation has been applied on the tip toward suction and pressure side and hydrodynamic performance have been discussed by using numerical investigation. Numerical results of the hydrodynamic characteristics of the propeller at the different blade tip angles are presented and discussed.
