Abstract
The effect of the circumferential non-uniformity of the thrust distribution on the propeller inflow is quantitatively investigated in the present paper: expressions are derived for the velocity potential and for various components of the inflow velocities resulting from this non-uniformity.
The calculation of the propeller inflow velocity for the case of a circumferentially uniform thrust distribution was presented in a previous paper. The objective of that work was to provide material for the calculation of the wake fraction and thrust deduction of a ship propeller. Jr was pointed out at the same time that the thrust deduction probably would be strongly affected by the circumferential non-uniformity of the thrust distribution and so the present task of calculating the velocities induced by this non-uniformity was initiated.
The study was conducted at the Experimental Towing Tank, Stevens Institute of Technology, under Office of Naval Research Contract No. N6onr-24705, sponsored by the Bureau of Ships under Project No. NS715-102, and technically administered by the Director, David Taylor Model Basin.
