AN ALTERNATIVE FOR THE PRODUCTION OF SCREW PROPELLERS IN AMAZÔNIA

Resumo :

ABSTRACT. IN THE AMAZON AREA, SHIPPING IS OF GREAT IMPORTANCE GIVEN THE EXTENSION OF NAVIGABLE RIVERS AND THE ABSENCE OF ALTERNATIVE MESHES IN THE AREA, ASIDES FROM THAT IT CONSTITUTES A CHEAPER MEAN OF TRANSPORTATION. MOST OF THE ECONOMIC ACTIVITY OF THE INTERIOR OF THE AMAZON STATES IS ACCOMPLISHED BY SHIPPING, THAT INVOLVES MOVEMENT OF REGIONAL PRODUCTS AS WELL AS PASSENGERS TRANSPORT, THUS PRESENTING GREAT RELEVANCE FOR THE STUDY OF THE SYSTEMS THAT INVOLVE THE PROJECT AND THE PRODUCTION OF SHIPS AND ITS COMPONENTS. NOWADAYS, THE HULL AND THE SCREW PROPELLERS ARE THE ONLY ONES PRODUCED IN THE AREA, AND THE PROPELLERS HAVE GREAT PART OF ITS PRODUCTION ACCOMPLISHED IN A HANDMADE WAY WHICH IS BASED UPON THE EMPIRICISM IN SMALL FOUNDRIES. THESE FOUNDRIES ARE INDUCED TO THE INEFFICACY, FOR THEY DON T CONTROL THE PROCESS, THE COSTS OR THE QUALITY OF ITS PRODUCTION. THE ANALYSIS OF THE SYSTEMS THAT COMPOSE THE SHIP INVOLVE A COMPLEX STUDY DUE TO THE AMOUNT OF INFORMATION THAT HAS TO BE WORKED, EMBRACING AREAS OF THE ENGINEERING SUCH AS FLUIDS MECHANICS, MECHANICS OF SOLIDS, MATERIALS, PRODUCTION ETC. ALSO, THE VARIETY OF COMPONENTS, LIKE AXES AND PROPELLERS, ENGINES, REDUCERS AND THE OWN STRUCTURE OF THE SHIP PRODUCE AN IMMENSE RANGE OF DATA TO BE ANALYZED IN THE NAVAL PRODUCTION. BASED ON THE FACT THAT THERE ISN T A REGIONAL RESEARCH CENTER WITH COMPETENCE IN NAVAL ENGINEERING AND THAT THE LOCAL INDUSTRIES DON T HAVE FINANCIAL RESOURCES, TECHNICIANS OR MATERIALS FOR RESEARCH AND DEVELOPMENT, THE OBJECTIVE OF THIS WORK IS TO PRESENT A GENERAL STUDY ON THE PROCESS USED FOR THE PRODUCTION OF SCREW PROPELLERS IN SMALL FOUNDRIES, IN THE METROPOLITAN AREA OF BELÉM, RAISING UP THE PARAMETERS THAT WILL MAKE IT EFFICIENT AND EFFECTIVE. KEYWORDS: SCREW PROPELLERS, AMAZÔNIA, QFD.
