ABSTRACTIn the Amazon, river navigation is very important due to the length of navigable rivers and the lack of alternative road networks. Boats usually operate in unfavorable conditions, since there is no hydrodynamic relation among propellers, geometry, and the dimensions of the boat hull. Currently, there is no methodology for propeller hydrodynamic optimization with low computational cost and easy implementation in the region. The aim of this work was to develop a mathematical approach for marine propeller design applied to boats typically found on Amazon rivers. We developed an optimized formulation for the chord and pitch angle distributions, taking into account the classical model of Glauert. A theoretical analysis for the thrust and torque relationships on an annular control volume was performed. The mathematical model used was based on the Blade Element Momentum Theory (BEMT). We concluded that the new methodology proposed in this work demonstrates a good physical behavior when compared with the theory of Glauert and the experimental data of the Wageningen B3-50 propeller.

For design of marine propeller, the energy supply from marine engine to the propeller should be converted to thrust force with minimum losses. Furthermore, the unwanted vibration and cavitation due to the overlooking a detail calculation of the propeller should be prohibited for increasing the fuel efficiency and life-span of the propeller. In the last few decades, most of small and medium sized enterprises (SMEs) focusing their work on ship component industry in Central Java Province Indonesia provide the marine propeller to the ship manufacturer and ship repairmen in some shipyards in northern part of Central Java port. The design of the propeller is never been observed and optimized. The aim of the present work is to redesign the installed propeller on a wooden fishing boat with the new optimized design using B-Series propeller theory approach. The reverse engineering method uses three-dimensional scanner to obtain the geometrical data of the installed ship propeller. The new optimized propeller design is obtained from free software calculation based on the boat and engine specification. The comparison shows that the new optimized propeller design has a wider blade and larger pitch and increases 20% of the open water efficiency of the propeller performance at lower engine rotation.

The demand for propellers of greatly increased efficiency that maximize fuel savings while minimizing both cavitation and propeller-excited vibrations has been driving the development of sophisticated computer programs for current application as well as into the 1990's and beyond. These programs enable the designer to evaluate the effects of geometry details without the necessity for—or at least greatly reduced reliance upon—costly and time-consuming model tests. This paper looks at these new propeller hydrodynamic design processes and examines the challenges faced by manufacturers to produce many different types of propellers that all meet highly exacting tolerance, materials, and performance criteria.

The time-varying cavitation on a marine propeller, which excites hull vibrations, is calculated. The analytical model is exercised to guide propeller design and operation in order to minimize this type of hull excitation. This model, as well as a more elaborate model under development at Massachusetts Institute of Technology, is compared with recent full-scale observations of propeller cavitation. The paper illustrates the importance of both accurate input data on scaled vessel wake velocities and the inclusion, in analytical models, of tip vortex cavitation.
