Abstract
A turbine blade is provided with a shroud having at least one cooling air passage extending through it. A plurality of small apertures in the passage direct cooling air as a film across the outer surface of the shroud thereby cooling it. The shroud is therefore thinner and lighter than previous shrouds which are typically provided with a large number of internal cooling air passages.
