Abstract

Un inversor de empuje para turborreactor de doble flujo, que comprende un capó o cubierta móvil (7) que forma, cuando el turborreactor funciona en empuje directo, el extremo posterior o de aguas abajo de la pared externa del canal anular (17) de circulación de la vena fluida, el cual se completa por un conjunto de alerones o paneles obstructores (12) que forman un conjunto anular, situándose la pared interna de los paneles obstructores (12) como prolongación de la pared radialmente más interna de la cubierta móvil (7), recubriendo dicha cubierta móvil (7), en empuje directo, un conjunto anular de parrillas de álabes o palas (20) portadas por la estructura fija del inversor, y desplazándose dicha cubierta móvil (7), en funcionamiento de inversión de empuje y bajo la acción de gatos (4) asegurados a la estructura fija de aguas arriba (6), en traslación en sentido de aguas abajo, con lo que arrastra los paneles obstructores (12), que giran en torno a un punto de articulación fijo (15) solidario con la pared interna (16) del canal anular (17) por la intermediación de balancines (14), con el fin de obturar dicho canal (17) y desviar el flujo, que se expulsa a través de las parrillas (20), proporcionando con ello una inversión del empuje, caracterizado porque, sobre cada sector periférico, una primera parte (21) de parrilla está fija y al menos una segunda parte (22) de parrilla es susceptible de moverse, situándose los álabes de la segunda parte (22) de parrilla en superposición radial con respecto a los álabes de la primera parte (21) de parrilla, en la configuración de empuje directo, y situándose los álabes de la segunda parte (22) de parrilla, en la configuración de funcionamiento con inversión de empuje y después de su traslación axial, yuxtapuestos a los álabes de la primera parte (21) de parrilla según la dirección longitudinal del turborreactor.
