Abstract

DISPOSITIVO DE POSICIONADO E INMOVLILIZACION AUTOMATICA DE PALAS PLEGABLES DE HELICOPTEROS. LAS PALAS (12) DEL ROTOR PRINCIPAL SON PIVOTABLES ALREDEDOR DE UN EJE LONGITUDINAL, EN RESPUESTA A LA POSICION DE UNAS BARRAS DE EMPUJE QUE CONTACTAN CON UN PLATO OSCILANTE (13) QUE ESTA CONECTADO A UNA SERIE DE SERVOMECANISMOS (17-19) QUE CONTROLAN EL EMPLAZAMIENTO DEL EJE DE INCLINACION, EL GRADO DE INCLINACION Y LA POSICION VERTICAL DEL PLATO OSCILANTE. CADA SERVOMECANISMO TIENE UN ELEMENTO DE ENTRADA MECANICO (23-25) DE UN MEZCLADOR (26) QUE RECIBE LAS ENTRADAS MECANICAS (27-29) DE CADA UNO DE LOS TRES EJES DE MANDO DE VUELO: PASO, DESPLAZAMIENTO Y ELEVACION. LA ENTRADA DE CADA SERVOMECANISMO (31-33) TIENE UN ACCIONADOR COMPENSADOR (39-41) QUE RESPONDE A UNA CONEXION ELECTRICA (42-44) DESDE UN COMPUTADOR DE MANDO DE VUELO AUTOMATICO (45).
