ABSTRACT:
Apparatus for the compact assembly of a gas turbine engine with a recuperative exhaust gas heat exchanger wherein inlet and outlet ducts of the core of the heat exchanger are supported by support plates attached to the casing of the heat exchanger. The support plates are connected to the engine casing with capability of relative movement between the ducts and the support plates so that thermally produced expansions and contractions are taken up without stress at the support points of the ducts with the support plates and within the heat exchanger. As a consequence, no expansion joints are necessary in the connection lines.
