ABSTRACT:
A seal for gas turbines includes first and second ends and a central section. The end sections have a greater thickness than the central section, thereby forming a recess about the central section. The ends are constructed using two offset radii such that they are substantially oblong-shaped to obtain an improved engagement capability. A filler material is provided in the recess to reduce the tendency of the seal to flop over at assembly.
