- W570960964 abstract "This paper presents from the practical point of view, a calculation method for the characteristics of an open-water propeller, based on the so-called QCM. The QCM method has been widely used in this field because of its simplicity, and especially for obtaining reasonable solution for various types of propeller. However, there exist certain problems in calculating using the QCM method, which shows unreasonable vortex distribution especially near the tip of propeller. This requires sufficient number of discrete loading points, as many as possible, and also a large storage computer in order to obtain the proper solution. For applying the QCM, the modified bound vortex system is introduced in this paper, which improves the unreasonable distribution. Also, the pressure distribution on the propeller surface is obtained using the solution obtained from the QCM method and the concept of the equivalent two-dimensional foil section, which consequently shows good agreement with the experimental results. Other problems referring to the effects of boss and trailing vortex contraction are also studied." @default.
