Abstract

La invención se refiere a un arreglo de alabes del rotor (20), especialmente para una turbina de gas, tal arreglo de alabes del rotor (20) puede ser afianzado sobre un portador de alabes (19) y comprende en cada caso un elemento de la superficie sustentadora del alabe (10) y un elemento de plataforma (14), en donde los elementos de plataforma (14) de una hilera de alabes, forman un refuerzo interno continuo. Con tal arreglo de alabes, un desacoplamiento mecánico, que extiende la vida útil en servicio, es logrado por el elemento de la superficie sustentadora del alabe (10) y el elemento de plataforma (14) que están formados como elementos separados y porque son capaces de ser afianzados en cada caso separadamente sobre el portador de alabe (19).
