Abstract
A configuration of seals disposed around and between a plurality of ring segments () arrayed annularly about the periphery of moving blades in a gas turbine engine. The seals function to retain coolant in the plenum () within each of the ring segments (). The seals are disposed atop a substrate (A), which forms the top of the plenum (). The first seal () is made of a piece of sheet material and seals the gap between adjacent ring segments. This seal has an edge (A) thereof creased for mating with a similar seal on an adjacent ring segment. A second seal (), which is also made of sheet material, seals the ends of the plenum () of the ring segments (). Lastly, a third seal (), which is also made of a piece of sheet material, seals the sides of the second seal ().
