Aircraft

An aircraft comprising

• a machine body enclosing a heat-exchanger module, a turbofan engine and a plurality of ancillary systems, the heat-exchanger module being disposed upstream of the turbofan engine, and the turbofan engine comprising, in axial flow sequence:
• a fan assembly;
• a compressor module;
• a turbine module;
• and
• an exhaust module,
• wherein:
• (a) the machine body (i) has first and second fluid inlet apertures configured to allow first and second inlet air streams to enter the machine body and (ii) further encloses an intake arrangement configured to blend the first and second inlet air streams together to produce a single blended inlet air stream therefrom and to output the single blended inlet air stream to the heat-exchanger module to provide a cooling airflow through the heat-exchanger module;
• (b) the heat-exchanger module is configured to transfer a waste heat load from the turbofan engine and the ancillary systems to the cooling airflow prior to entry thereof into the fan assembly;
• and
• (c) in operation of the aircraft, all active aircraft cooling is provided by the blended inlet air stream and the machine body is otherwise free of fluid inlet apertures and scoops for providing cooling airflows for the aircraft.
