Abstract

The present invention relates to an aircraft comprising a fuselage () and a propulsion unit at the rear of the fuselage, the propulsion unit comprising at least one fan rotor (), a nacelle () fairing the fan and at least one connection means () connecting the nacelle to the fuselage, the fan being rotated by the energy supplied by at least one gas-turbine gas generator () housed in the fuselage, said gas generator comprising auxiliary equipment cooled by a cooling circuit. The aircraft is characterised in that said cooling circuit comprises at least one heat exchanger exchanging heat with the ambient air housed in one of said connection means () and/or in said nacelle (). The cooling circuit optionally comprises also a heat exchanger exchanging heat with the ambient air, housed in the tail unit.
