Eliche Radice was founded at the beginning of the last century (in 1919) and the Radice family own the company still today. This could be precisely family formula, alongside a continual appraisal of the market that has led to the formation of a management structure capable of facing and managing today’s complex problems in a continuously evolving market with autonomy and dynamism. The company structure in Italy covers over 50,000 m² and 15,000 m² of this area cover around 85 employees while a commercial base in France (ER France) is added to this part. The Eliche Radice foundry (600 tonnes of annual capacity) is the result of a continuous technological evolution, a perfect match between experience and research, and the essential factors to achieve positive results. In 90 years of activity almost all the problems of propulsion in general and more specifically those related to the propellers, have been faced and solved to the proven satisfaction of their customers from the most varied naval sectors. Each single propeller project is the result of years of meticulous direct experimentation performed in cooperation with the principal research institutes and naval tanks from all over the world. This vast data archive is the basis of the calculation programs used for defining the parameters of each project and the production drawing. The planning department directly develops the calculation programs which, by examining all the possible alternatives, are able to offer the best possible solutions in terms of number of blades, area disks (DAR) and pitch/ diameter (P/D) ratios always keeping in mind the criteria of efficiency, silence, vibrations and cavitation. The planning is not limited to the propellers only: it also includes design questions related to the various components of the shaft lines produced by Eliche Radice. New materials and technical solutions are constantly being tested so that they can always offer the most efficient solutions. In today’s planning 3D-CAD stations are used in order to facilitate the direct data transfer to the CNC. They are focesed to propellers; shaft Lines, struts/ rudders/ bearings.
