Abstract
The propelling performance of the Voith-Schneider-Propeller is dealt with here theoretically by an approximation method, making use of results of the preceeding two reports. When the solidity is small, the value of thrust is obtained by superposing the variation of lift and drag of blades caused by the induced velocities on the result by the treatment as quasisteady-state. For the case the solidity is not so small, uniform decrease of the bound vortices of blades with a definite ratio is assumed, which enables to make use of the preceeding reports effectively and to give an account of propelling performance in a simplified form though approximately. Assuming the same character of propeller blades, some efficiency diagrams are given here also.
