Abstract

HELICES DOTADAS DE PLACAS. SE CONSTRUYEN INCORPORANDO UNA O VARIAS PANTALLAS DE PLACAS SOBRE LA HELICE CON LO QUE SE IMPIDE EL FLUJO DE LIQUIDO EN DIRECCION RADIAL, SE PRODUCEN LOS TORBELLINOS EN EL EXTREMO DE LA PALA QUE REDUCIAN EL EMPUJE DE LA HELICE Y SE EVITAN LOS PROBLEMAS DE CAVITACION. EN CONTRAPARTIDA, LA INCLUSION DE ESTAS PANTALLAS OCASIONA PERDIDAS DE RAZONAMIENTO, PERO SE PUEDEN REDUCIR AL MAXIMO MIRIALZANDO EL AREA DESARROLLADA DE LA PANTALLA. DICHA PANTALLAS DEBERAN SER TRAZADAS Y DIMENSIONADAS DE ACUERDO CON EL DISEÑO DE LA POPA DEL BARCO, SU UNION A LA HELICE SE PUEDE REALIZAR MEDIANTE SOLDADURA O REALIZARSE MEDIANTE FUNDIDO EN EL PROPIO PROCESO DE CONSTRUCCION DE LA HELICE.
