| 摘要 |
The aim of the invention is to provide a turbine engine architecture having a heat exchanger built into the exhaust line (10). The turbine engine is a turboshaft engine (20) comprising a gas generator (22) and a free turbine (27) supplying power to the shaft (30) via a through-shaft (28) and an upstream reduction gear (29). An annular plate-shaped exchanger (60) is installed in the axisymmetric portion of the ejector (16) and consists of an inlet channel (61) and an outlet channel (62), connected to the inlet and outlet of a central channel (6) wound into the shape of a helix or sine curve in the annular plate (60). The channels (61) and (62) are connected at the other ends thereof to mechanical or electromechanical means for recovering and recycling the energy in order to improve the overall performance of the turbine engine. The energy is recovered via a cold fluid which is heated in the central channel (6) by the transfer of the heat from the residual gases (1). |
