ON THE DESIGN OF NON-OPTIMAL PROPELLERS

A new method of modifying the circulation distribution is presented, based on a scheme of reducing the propeller loading near the hub and the tip by certain percentages. A design example is worked out using both the "Eckhardt-Morgan" design method and the induction factor method by "LERBS", together with the non-optimal circulation distribution. The results show clearly the favourable effect on the cavitation characteristics with a negligible loss in the propeller efficiency.
