ABSTRACT:
A gas turbine engine is provided with a novel heat exchanger which exchanges heat between the compressor delivery air and turbine exhaust gas. The exchanger comprises a stack of rotary discs angled to produce two sets of wedge-shaped flow areas between them; turbine exhaust gases flow through the discs from one set of areas to the other and heat the discs, while the compressor delivery air flows through a segment of the discs in the reverse direction to exhaust the heat.
