Abstract
A gas turbine arrangement includes a rotor, a hot-gas passage, through which a hot-gas stream () flows while the gas turbine is operating, at least one first row of turbine blades or vanes (), which have an airfoil() with a suction side () and a pressure side (), and a platform (), and at least one second row of turbine blades or vanes (), which are arranged upstream of the first row of turbine blades or vanes () in the direction of the hot gases (), and in the axial direction of the rotor and likewise have a platform (). There is at least one seal (), through which a cooling air leakage stream () emerges while the gas turbine is operating, between the first row of turbine blades or vanes () and the second row of turbine blades or vanes (), in the region of the respective platforms (). An element guides the leakage stream () of cooling air along the surface of the platform () to the pressure side () of the first row of turbine blades or vanes ().
