Abstract:
A deflector for guiding a cooling fluid to a blade device of a turbine is provided. The deflector includes a first opening region with a first opening shape and a second opening region with a second opening shape. The deflector is connectable to a first blade device and to a second blade device in such a way that the cooling fluid is streamable through the first opening region into the first blade device and the cooling fluid is streamable through the second opening region into the second blade device. The first opening shape differs from the second opening shape for achieving a predetermined first mass flow of the cooling fluid into the first blade device and a predetermined second mass flow of the cooling fluid into the second blade device at predetermined installation locations of the first blade device and the second blade device.
