Abstract
Gas turbine engine seals and engines incorporating such seals are provided. In this regard, a representative seal includes: an annular seal body having an inner diameter and an outer diameter, the seal body extending along an axis of symmetry between a first end and a second end; the seal body being formed of a strip of material having first and second opposing edges, the strip of material being deformed to exhibit a first sealing surface at the first end, a second sealing surface at the second end, and a third sealing surface along the inner diameter, the first edge being located adjacent to the third sealing surface, the second edge being located adjacent to the second sealing surface; the first edge being spaced from the second edge to define an annular opening, the annular opening providing access to an annular cavity of the seal body.
