Abstract
An aircraft (41) including a fuselage (14) having a skin (15) and extending along a longitudinal axis (39) from a front end to a rear end (17) of the aircraft, and an engine (30) including an air intake (31) forming an opening in the skin (15) and an exhaust (32) forming another opening in the skin (15). The engine is in a rear fuselage section, in which the exhaust (32) is situated ahead of the air intake (31) along the longitudinal direction (39).
Claims20
An aircraft comprising:
- a fuselage including a rear fuselage section having a skin extending around a circumference of the rear fuselage section, wherein the rear fuselage section includes a rearwardly facing end;
- an engine housed within the rear fuselage section, wherein the engine includes an air intake inlet configured to intake air for combustion in the engine and an exhaust outlet configured to discharge exhaust gases from the engine;
- an air intake duct within the rear fuselage section and configured to direct air into the air intake inlet of the engine;
- an air intake opening in the skin of the rear fuselage section, wherein the air intake is forward of the rearwardly facing end and forms an air inlet to the air intake duct;
- an exhaust duct within the rear fuselage section, having an inlet connected to the exhaust outlet and configured to direct the exhaust gases generated by the engine away from the engine;
- and
- an exhaust opening in the skin of the rear fuselage section and forming an outlet to the exhaust duct, wherein the exhaust opening is configured to discharge the exhaust gases into atmospheric air adjacent the aircraft;
- wherein the exhaust opening is forward of the rearwardly facing end and forward of the air intake opening along a longitudinal axis of the fuselage, and
- wherein the air intake inlet of the engine is forward in the fuselage of the exhaust outlet of the engine.

A rear fuselage section of an aircraft comprising:
- a skin defining an outer surface of the rear fuselage section;
- a rear end facing rearward of the rear fuselage section;
- an auxiliary power unit engine including an air intake inlet configured to intake air for combustion in the auxiliary power unit engine and a combustion gas discharge aft of the air intake inlet;
- an air intake duct having an outlet connected to a combustion air intake of the auxiliary power unit engine;
- an air intake opening in the skin of the rear fuselage section and forward of the rear end, wherein the air intake opening is an inlet to the air intake duct;
- an exhaust duct having an inlet connected to the combustion gas discharge outlet of the auxiliary power unit engine;
- and
- an exhaust opening in the skin of the rear fuselage section, wherein the exhaust opening is at an outlet of the exhaust duct,
- wherein the exhaust outlet is forward of the air intake opening and is forward of the rear end along a longitudinal axis of the rear fuselage section.
