THEORETICAL STUDY ON MARINE PROPELLER PERFORMANCES USING THE RHEO-ELECTRICAL ANALOGY TECHNIQUE

Abstract

This report includes: EX ENSION OF E THEORY OF JONES TO MARINE PROPELLER, PART I, by P. Sulmont. 1961, 27p. illus. 8 refs.ANALOG STUDY OF PROPELLERS BY MEANS OF THE LIFTING LINE THEORY, PART II, by P. Sulmont. 1961, 14p. incl. illus. Marine propellers generally have a relatively large fraction of developed area therefore and hav blades with a relatively small aspect ratio, provided the number of blades is not very large. Lifting line theory is therefore inapplicable, particularly for the determination of the camber of the profile. For this reason, a heory is developed similar to the theory of Jones applied to small-aspect ratio wings. In this theory, it is assumed that the variat ons in the perturbation potential in the direction of the flow are small; the problem is therefore reduced to the study of an harmonic potential in a plane perpendicular to the direction of the flow. This limit-case will also enable the exp rimenter to etermine the domain in which lifting-surface theory can be applied effectively to propeller. (Author)
