Abstract: A heat exchanger has: an inlet manifold having an inlet port; and an outlet manifold having an outlet port. A first gas flowpath passes from the inlet port to the outlet port. A plurality of plate banks are positioned end-to-end, each plate bank having a plurality of conduits with interiors along respective branches of the first gas flowpath, a second gas flowpath extending across exteriors of the plurality of conduits. One or more docks couple adjacent ends of the plurality of plate banks.

Abstract: An annular finger seal includes a base portion defining a base edge of the annular finger seal and having a center pass-through aperture. The base edge may be substantially continuous. The annular finger seal may also include a finger portion defining a finger edge of the annular finger seal and including a plurality of fingers. The finger edge may be segmented by gaps disposed between adjacent fingers of the plurality of fingers. A gas turbine engine includes a combustor section, a turbine section, and an annular finger seal. The annular finger seal includes a plurality of fingers and the annular finger seal is disposed at an adjoining interface between the combustor section and the turbine section. The annular finger seal may be mounted to the turbine section and may engage a radially inward facing surface, relative to the engine central longitudinal axis, of the combustor section.
