摘要

The de-icer for turbine blade (10) comprising a fixed forward section (12) and a movable rear flap (18) consists of at least one emission slot aligned in a fore and aft direction along the trailing edge (16) of the hollow U-shaped fixed section of the blade to direct heated air onto the flap. A single slot is aligned with the inner surface of the blade or, where there are two slots, with both inner and outer surfaces. The emissions slots, made from embossed metal sheet, can have a constant or tapering cross-section and can be angled upwards or downwards.
