Abstract
A finger seal for a gas turbine engine is disclosed. The finger seal includes a first leg, a second leg, a third leg, a fourth leg, a first bend segment disposed between the first leg and the second leg, a second bend segment disposed between the second leg and the third leg, and a third bend segment disposed between the third leg and the fourth leg. The third bend segment is radially outward of the first bend segment relative to an axial centerline of the gas turbine engine.
