Abstract

SE PRESENTA UNA DISPOSICION DE PETALOS DIVERGENTES PARA TOBERAS CONVERGENTES-DIVERGENTES CON CAPACIDAD DE VECTORIZACION DE EMPUJE A TRAVES DE LOS CAMBIOS EN LA GEOMETRIA DE LA SECCION DIVERGENTE, EN DONDE LA POSICION DE CADA PETALO AUXILIAR DIVERGENTE (4) SE DETERMINA MEDIANTE UN MECANISMO CENTRADOR (31), CONSTITUIDO POR DOS BARRAS CENTRADORAS (14 Y 27) QUE SE DESLIZAN A TRAVES DE ELEMENTOS DE GUIA (17 Y 18) DE LOS PETALOS DIVERGENTES PRINCIPALES (2), SE FIJA UNA POSICION AXIAL CENTRADA ENTRE LOS PETALOS DIVERGENTES PRINCIPALES (2) Y MEDIANTE UN ELEMENTO SUSTENTADOR (13) QUE CHOCA CON LOS ELEMENTOS DE TOPE (25) DE LOS PETALOS DIVERGENTES PRIMARIOS SE LIMITA EL DESPLAZAMIENTO A OTRA POSICION AXIAL, EVITANDO AL MISMO TIEMPO Y EN CONJUNCION CON EL MECANISMO CENTRADOR (31) EL DESPLAZAMIENTO DEL PETALO DIVERGENTE AUXILIAR (4) SEPARANDOSE DE LOS PETALOS PRIMARIOS (2) CUANDO LAS FUERZAS DE LA PRESION ACTUAN DESDE EL LADO DEL AIRE HACIA EL LADO DEL GAS.
