OPERATING CHARACTERISTICS OF CONTROLLABLE PITCH PROPELLERS WITH NEGATIVE ADVANCE RATIOS

CARACTERISTICAS DE FUNCTIONAMIENTO DE PROPULSORES DE PASO REGULABLE EN GRADOS DE AVANCE NEGATVOS

The use of controllable pitch propellers is gradually increasing, for ships of all types, owing to the advantages they offer in some of their operating aspects. The main advantages of these propellers are the following: 1. The possible absorption of the total available engine power, at the nominal rpm, in any loading condition. 2. Easy ship handling enhanced by the manual propeller pitch control. In studying the most adequate propeller pitch position, when going astern, it is necessary to have information on the operating characteristics of these propellers with negative advance ratio. In order to add to the scarce data now existing about this subject, the results of tests carried with negative advance ratio, for three C.P.P., are presented in this paper.
