Abstract

Un rotor de turbina de gas tiene una disposición de aire de enfriamiento de circuito enla que aire de enfriamiento extraído desde el aire se descarga delcompresor que es suministrado a la cámara de combustión es además comprimido, enfriado y luegodirigido hacia el extremo posterior del rotor de turbina.Anillos de cierre de corriente abajo asegurados a la cara de corriente abajo de cada disco de rotor dirigen el aire de enfriamiento sobre la cara decorriente abajo del disco para de esemodo enfriarlo, y luego hacia pasajes de aire de enfriamiento formados en las palas rotatorias. Anillos de cierre decorriente arriba asegurados a la cara de corriente arriba de cada disco dirigen el aire de enfriamiento calentado para alejarlo dela bas e de la pala rotatoriaa la vez que mantienen el disco aislado térmicamente del aire de enfriamiento calentado. A partir de cada anillo de cierre de corriente arriba, el aire deenfriamiento calentado fluye por pasajes formados en los discosde corri ente arriba, y es luego combinado y devuelto a la cámara de combustión desde dondefue extraído.
