Abstract
Starting from the basic equations of the fluid mechanics relations between the velocity field induced far behind the propeller and extrernal forces representing a screw propeller generating this field have been derived in the paper. The model adopted for calculations has been based on a system of concentrated vortices with cavitation singularities of a vortex core.
The relations derived make it possible to determine ideal hydrodynamic characteristics of a screw propeller. Exemplary characteristics for selected vortex systems in various coordinates systems have been presented in the paper.
