Abstract
SISTEMA DE CONTROL DE DIRECCION DE HELICOPTERO BASADO EN LA VARIACION DEL PASO DE LAS PALAS DE LOS DOS ROTORES. CONSTA DE UNA CAJA ROBUSTA (1) EN LA QUE SE ALOJAN DOS CORONAS (2,3) ACCIONADAS POR UN PIÑON (4), CUYA POTENCIA LA RECIBE DEL MOTOR A TRAVES DE UN EMBRAGUE CENTRIFUGO. EN CADA UNA DE LAS CORONAS, MEDIANTE LOS CORRESPONDIENTES JUEGOS DE RODAMIENTOS DE BOLAS, SE AJUSTAN LOS EJES (5,7), QUE MUEVEN RECPECTIVAMENTE LAS PALAS DE LOS ROTORES INFERIOR (6) Y SUPERIOR (8), HACIENDO GIRAR LAS DEL PRIMERO EN UN SENTIDO Y LAS DEL SEGUNDO EN SENTIDO CONTRARIO. UN SISTEMA DE VARILLAS (13) CONECTADO CON LAS PALAS DE LOS ROTORES Y CON TRES JUEGOS DE ARTICULACIONES (12) UNIDAS A UN DISCO (11) QUE A SU VEZ ES ACIIONADO POR DOS PALANCAS (18,14), PERMITEN DIRIGIR Y CONTROLAR EL HELICOPTERO.
