<p>A sheet metal seal for sealing the gap between adjacent blade platforms in a rotor assembly fits within a pair of spaced apart slots on the underside of one of the platforms and is trapped in position by a lug disposed between the slots and which passes through a hole in the seal. The seal is attached to the blade prior to its assembly in the disk. A portion of the seal overhangs the edge of the platform to which it is attached and, when the blade is inserted into the disk, the extended portion of the seal overlies the underside surface of the adjacent blade platform. This seal is preliminarily shaped to the contour of those portions of the underside surfaces of the platforms against which they are to bear during rotation of the assembly.</p> |
