GAS TURBINE COMPRISING A COMBUSTOR WITH A COMBUSTOR OUTLET AND A FIRST ROW OF ROCKING VANES

摘要

A gas turbine (10) comprises a combustor with a combustor outlet and a first row of rocking vanes (12) arranged at said combustor outlet in sealing relationship with said combustor outlet, whereby said rocking vanes (12) each comprise an airfoil (13) with a leading edge (13a) and a trailing edge (13b) extending between an inner platform (15) and an outer platform (14), and whereby said rocking vanes (12) are each hooked with their outer platform (14) into a turbine vane carrier (17) thereby defining a rotation point (19) for a rotational movement of said rocking vanes (12). The rocking vane movements and the axial force on the inner platform are reduced by moving said rotation point (19) to the leading edge (13a) of said rocking vanes (12).
