ABSTRACT:
A seal for stator vane segments within a gas turbine engine is provided which includes an axial member and an end member. The axial member includes a central portion and at least one axial joint element extending out from the central portion. The central portion has across-section which includes a pair of substantially u-shaped circumferential ends connected by an arcuate midsection. The axial joint element transitions from the arcuate midsection to a substantially flat end. The end member includes an end joint element attached to a radial portion. The axial and end joint elements contact each other to prevent leakage therebetween, and also sidably cooperate with each other to accommodate misalignment between the axial member and the end member.
