Abstract
Prior art recuperators or heat exchangers have been restricted in use to only part speed and power application when adapted for use with high pressure gas turbine engine. The present recuperator or heat exchanger has been adapted for use with a high pressure ratio gas turbine engine. The recuperator includes a plurality of air cells being formed by a plurality of primary surface sheets. The primary surface sheets define a first surface and a second surface and has a plurality of corrugations formed therein. Each of the plurality of corrugations has a crest and a root extending from the respective first surface and second surface a preestablished axial distance. The preestablished axial distance from the crest to the first surface being unequal to that of the preestablished axial distance from the root to the second surface.
