Abstract
A propulsion system for an aircraft includes a heat exchange unit through which a hot air stream and a cooling air stream flow. The heat exchange unit includes a hot air inlet pipe situated on a rear face of the heat exchange unit, to carry the hot air stream into the heat exchange unit, and a cooling air discharge pipe situated on the rear face of the heat exchange unit to expel the cooling air stream from the heat exchange unit, the hot air inlet pipe and the cooling air discharge pipe being concentric with each other. The hot air stream flows from the rear face forward to a front of the heat exchange unit, then from the front of the heat exchange unit, to a rear of the heat exchange unit, so as to be expelled via the rear face of the heat exchange unit.
