Tutorial design a boat screw propeller (2) the operating parameters and geometry tutorial design a boat screw propeller (1) tutorial design a boat screw propeller (2). Latorre [3] developed a design procedure of this type of propeller, applying it, years later, the development of a helix called semi-kaplan, with changes in the distributions of ropes and steps with these propellers show that the new design procedure introduced an improvement about 10% of the propulsive efficiency of boats, comparing fuel.

A propeller for propulsion of an electric boat. we ate here for example, a boat ride, 5 meters, powered by an electric motor supplied by a source of 300 w . this low power required quality and efficiency to the screw propeller!. Matching propeller to your boat. a good match between your boat, the engine and the propeller is essential. it is a complex relation, with many inter-related factors. only the basic parameters and very simplified practical methods of selecting the propeller size are given here to help you understand the subject better.. In this context pitch describes the path a propeller would take for one complete rotation without any slip. since this idealized parameter cannot be determined on a moving boat (slip always occurs in practice), the pitch of a propeller is measured with the help of the angle of attack of its blades..
