Abstract
A gas turbine engine turbine blade (20) has cooling air holes (38) arranged in groups, the holes (38) in one group and which span that part of the leading edge (34) that spans the hottest part of the blade (20), are more closely spaced than the remainder of the holes (38), thereby ensuring the provision of the most cooling air, where it is most needed.
