CONTROLLABLE PITCH PROPELLERS WITH GAS TURBINE PRIME MOVERS

The paper is concerned with the transient performance of gas turbine/controllable pitch propeller ships propulsion plants in the decelerating mode with headway on the vessel. Conventional propeller coefficients are examined, and their deficiencies for this purpose noted, particularly with regard to preliminary predictions of performance in the initial ship design phase. A tentative set of revised coefficients is proposed, and the predictions compared to two sets of full-scale data.
