Blade of a rotary flow machine with a radial strip seal

摘要

The invention refers to a blade (1) of a rotary flow machine comprising
an airfoil (2) having a suction surface (3) and a pressure surface joining each other along a trailing and a leading edge (4, 5), a radially outward directed airfoil tip and a radially inward directed end joining an inner platform (6) connecting the airfoil to a shank (7) at a radial end of the airfoil and providing, at least one shank pocket (8) radially encircled by an axially extending portion of the platform and at least one radially extending rim (9) that extends from the trailing edge side of the shank and has an essentially radially orientated first slot (10) for receiving a seal (11), and a mount (12) extending radially inwardly from said shank pocket. Said first slot has a first aperture (13) on a shank surface orientated in an axial direction.
