Abstract

UN ACCIONAMIENTO PROPULSOR A HELICE CON ENVOLTURA (2) PARA UN AVION, PRESENTA PARA LA INVERSION DEL EMPUJE, PALETAS DE ROTOR REGULABLES (3) PARA INVERTIR LA DIRECCION DEL FLUJO EN EL INTERIOR DE LA ENVOLTURA Y UN ANILLO DE TOBERA (4) EN EL EXTREMO POSTERIOR DE LA ENVOLTURA, EL CUAL FAVORECE DURANTE LA INVERSION DE LA DIRECCION DEL CHORRO DEL FLUJO EL REFLUJO DEL FINAL DE LA ENVOLTURA. ESTA EJECUCION PRESENTA LA VENTAJA DE QUE LAS PALETAS DEL ROTOR DURANTE EL SERVICIO DE LA INVERSION DEL EMPUJE ESTAN SOMETIDAS A UNA TURBULENCIA MENOR Y CONSECUENTEMENTE GENERAN UN MAYOR EMPUJE DE INVERSION.
