In order to improve the hydrodynamic and cavitation performance of the hydrofoil, some hydro-foil section design methods with specified pressure distribution are developed. However the section is de-signed at a given angle of attack in the most of such methods, which may result in large computation cost and difficulties in convergence especially when the methods are extended to 3-D problems. In the paper, a new 2-D hydrofoil section design method is proposed based on surface panel method of the potential theo-ry. The velocity potential flux and geometric corrections of the blade surface can be obtained by solving total velocity potential equation with specified pressure distribution on the blade surface. The geometric correction could be decomposed into two parts. One is owing to the change of angle of attack, and the other is the change of profile itself. In this way, the unique design angle of attack and section geometry for specified pressure distribution can be attained. The numerical results show that the method is robust and valid.
