Abstract
ESTA INVENCION SE RELACIONA CON UN VANO DE UNA TURBINA DE GAS (17) QUE TIENE UN REVESTIMIENTO INTERIOR (26) REFRIGERADO POR UNA PORCION DE AIRE DE REFRIGERACION DIRIGIDO A LA CAVIDAD (45) ENTRE DOS FILAS ADYACENTES DE DISCOS (55, 56). UNA PORCION DEL AIRE DE REFRIGERACION EN LA CAVIDAD FLUYE POR UNAS PLACAS DE IMPREGNACION (83, 84) Y SE IMPREGNAN EN LA SUPERFICIE INTERIOR (98) DEL REVESTIMIENTO INTERIOR (26). OTRA PORCION DEL AIRE DE REFRIGERACION FLUYE POR UN PASO (83) EN EL BORDE DE CONDUCCION (42) DEL REVESTIMIENTO INTERIOR QUE TIENE UN SISTEMA DE ALETAS DE PIVOTE (89) PARA AUMENTAR LA REFRIGERACION. LAS PLACAS DE IMPREGNACION FORMAN UNAS CAMARAS QUE RECOGEN EL AIRE DE IMPREGNACION Y EL AIRE DEL PASO DE LAS ALETAS DE PIVOTE Y LO DIRIGEN POR UNOS AGUJEROS (92) EN EL BORDE DE ARRASTRE (43) DEL REVESTIMIENTO INTERIOR PARA ENFRIAR EL BORDE DE ARRASTRE. UNOS PASOS LONGITUDINALES (93, 94) A LO LARGO DEL LATERAL DEL REVESTIMIENTO INTERIOR DIRIGE EL AIRE DE REFRIGERACION DESDE EL PASO CON LAS ALETAS DE PIVOTE HASTA EL BORDE DE ARRASTRE (43).
