NEW RELATIONS BETWEEN PROFESSIONAL AND WORK'S ORGANIZATIONS INTRODUCED BY COMPUTER APPLICATIONS, SPECIAL VESSEL CASE STUDY

摘要

The present paper will present the case study of the use of Computers in optimization of the project of an hydrofoil, describing the general approach at the project and the various steps that must be followed, in order to underline how the use of computers has made possible the optimization trough an interactive procedure that was not possible to adopt in the past, with traditional systems. It is interesting because, how is well known, the theory of hydrofoils and first applications was coming from 1910 with Forlanini, but only in last years it has been possible a scientific approach at optimization of wing profiles through the use of CAD/CAM systems. At present time the project of a naval vehicle, where with the word project we refer to all the process of design and manufacturing, especially when the vehicle offers special formal and performance characteristics, involves a number of operators that has been increasing considerably in recent decades, and this increased complexity can be correlated with dimensional and typological growth of many categories of ships. Simultaneously we are witnessing a complete new project approach, where the possibility given by the computer contribution to represent processes and results becomes crucial. The paper aims to investigate the consequences of this progress in the organization of the project and focuses on the innovative methodologies, bringing as an emblematic case the evolution of the hull study and the role of "planning matrix" that it also constitutes even on the graphic plane. The studio cases examined, which the reflections presented here refer to, are related to ships where the combination of performances and shapes takes on a particularly significant value: therefore, references are made to yachts and fast vehicles such as hydrofoils or catamarans. Finally, with special regards to Hydrofoils, the study will report a comparison made about the seakeeping and resistance of 2 different types of wings for hydrofoils, the comparison has been done at first step by using CFD calculations and then validated trough tank tests to show the validity of the results.
