Abstract

PETALO DIVERGENTE PARA UNA TOBERA DE TURBINA DE GAS. ESTE PETALO (2) ESTA ARTICULADO EN SU BORDE DELANTERO PARA FORMAR UN PETALO DIVERGENTE (1) POR MEDIO DE UNA UNION CILINDRICA (4) MIENTRAS QUE SU SUPERFICIE POSTERIOR ESTA ARTICULADA EN UN PUNTO INTERMEDIO CON UNA BARRA DE COMPRESION (5) POR MEDIO DE LA UNION CILINDRICA (6), SIENDO LAS UNIONES CILINDRICAS (4 Y 6) PERPENDICULARES AL EJE DE LA TURBINA. EL PETALO (2) ESTA FORMADO POR UNA BARRA DE TRACCION (11) Y UNA PLACA BASE AERODINAMICA (10) QUE FORMA EL CONDUCTO DE LA TOBERA, ESTANDO AMBOS COMPONENTES UNIDOS ENTRE SI POR UNA UNION DELANTERA (13 - 16) QUE COINCIDE CON LA UNION CILINDRICA (4) ENTRE LOS PETALOS CONVERGENTE (1) Y DIVERGENTE (2) Y UNA UNION POSTERIOR (14 - 18) QUE COINCIDE CON LA UNION (6) ENTRE EL PETALO DIVERGENTE (2) Y LA BARRA DE COMPRESION (5), SIENDO DICHA JUNTA POSTERIOR (14 - 18) DESPLAZABLE UNA CIERTA DISTANCIA EN UNA DIRECCION FUNCIONALMENTE PARALELA A LA PLACA BASE (10).
