Un programma di calcolo per eliche navali moderatamente caricate basato sulla teoria dei fattori d'induzione

This report presents a computer program particularly adapt to design moderately loaded propeller being based on the induction factors method according to "exact" lifting line theory. The first section of the paper illustrates the employed method to calculate lift coefficientsm induced velocities and hydrodynamic pitch angles, not only for wake adapted, but also for arbitrary radial loaded propellers. Section two illustrates the approach for stress and cavitation computations needed to pass from hydrodynamic to geometrical propeller bleda design. The last section shows how three.dimensional surface effects are taken into account by introduction of correction factors calculated from the lifting surface theory. In addition, some examples of practical applications and a detailed explication of input/output program data are given.
