Abstract
A seal is provided between an inner flowpath and inner band of a turbine frame for confining cooling air channeled therebetween. The seal includes a frustoconical seal support and a radially outer seal ring integrally joined to a smaller diameter distal end of the support. A radially inner ring is fixedly joined to the inner band coaxially with the outer ring and is spaced radially inwardly thereof to define a gap therebetween sized for limiting leakage of cooling air from a chamber defined between the seal and inner flowpath.
