Abstract
SISTEMA DE MONTAJE DE LA ESTRUCTURA DEL ROTOR DE HELICOPTEROS PARA REDUCIR VIBRACIONES. CONSISTE EN UNA SERIE DE PALANCAS INTERMEDIAS DE SUSTENTACION, ENTRE LA ESTRUCTURA Y EL FUSELAJE DE HELICOPTERO, QUE TIENEN UN REGIMEN ELASTICO COMPUESTO PARA UN PESO DADO DE LA ESTRUCTURA DEL ROTOR, QUE ESTABLECE UN SOPORTE RESILIENTE PARA EL FUSELAJE, DESDE LA ESTRUCTURA DEL ROTOR AL EMPUJE REQUERIDO PARA SOSTENER EL FUSELAJE EN VUELO NORMAL, SIENDO MINIMA LA FUERZA VERTICAL OSCILATORIA TRANSMITIDA AL FUSELAJE PARA DEFLEXIONES ESTATICAS ACEPTABLES DEL ROTOR. TAMBIEN COMPRENDE UNOS TOPES QUE LIMITAN LA DEFLEXION ENTRE LA ESTRUCTURA DEL ROTOR Y EL FUSELAJE, PARA UN EMPUJE PRETERMINADO DEL ROTOR, POR ENCIMA DEL EMPUJE NORMAL. P
