Turbo jet engine with heat exchanger

摘要

The turbojet engine has a heat exchanger(5) located between the compressor(1) and combustion chamber(2). At least one hot gas duct(6) branches from a region after the HP turbine(3) and is connected to the heat exchanger. At least one cold gas duct(7) connects the heat exchanger to a region in front of the LP turbine(4). The heat exchanger in the form of a diffusor or cross flow heat exchanger is constructed to feed through the whole amount of air flowing from the compressor.
