Abstract (en)
[origin: EP1496203A1] The turbine blade has impingement cooling of the thermally highly loaded outer wall sections (2a-2f). At least one partition (3-5) is provided inside the hollow blade to form a cooling air chamber (6), and in the partition are impingement air passages (7) to direct cooling air to the inner face of the hot outer wall section. The impingement air passages are concavely curved with regard to the adjacent outer wall and are arranged parallel to it and completely in the hot outer region. The impingement air passages have an elongated hole-like or elliptical cross sectional face, the orientation of the longitudinal axis of which coincides with the radial blade orientation.
