Abstract

PERFECCIONAMIENTOS EN HELICES DE SUSTENTACION PARA AERONAVES.CONSISTENTES EN: A) CADA UNA DE LAS DOS PALAS GIRA RESPECTO AL PRIMER EJE LONGITUDINAL POR UN PUNTO DE SU PERFIL TRANSVERSAL DISTANCIADO DEL CENTRO AERODINAMICO DEL MISMO UNA DETERMINADA DISTANCIA, CON LO CUAL, AL GIRAR Y AVANZAR SIMULTANEAMENTE LA HELICE, SE CREAN EN CADA UNA DE LAS PALAS PARES ANTAGONISTAS QUE SE EQUILIBRAN AL IR VARIANDO AUTOMATICAMENTE EL ANGULO DE ATAQUE DE CADA UNA DE LAS PALAS SEGUN LA POSICION EN QUE SE ENCUENTRAN RESPECTO AL MOVIMIENTO DE AVANCE; B) CADA UNADE LAS PALAS ESTA PROVISTA DE UN RESORTE DE EQUILIBRIO PARA GARANTIZAR EN LAS PALAS ANGULOS DE ATAQUE IGUALES AL INICIAR LA ROTACION, Y DE UN AMORTIGUADOR ASOCIADO AL RESORTE, PARA SUAVIZAR LAS OSCILACIONES Y LAS VIBRACIONES; C) LAS HELICES ESTAN PROVISTAS DE UN DISPOSITIVO QUE PERMITE VARIAR EL ANGULO DE ATAQUE DE CADA UNA DE LAS PALAS TANTO EN REPOSO COMO EN ROTACION O EN VUELO.
