Abstract

The invention refers to an aircraft tailcone (1) comprising: a tailcone fuselage (2), an turbomachine (for example an APU) (4) housed inside the tailcone (1), a RAM air intake (6) on the tailcone fuselage (2) for the ingestion of RAM air towards the interior of the turbomachine compartment (3), an inlet flap (7) operable reciprocately from an open position in which ingestion of RAM air is allowed, and an closed position in which RAM air ingestion is prevented. The RAM air intake (6) extends annularly along a perimeter of the tailcone fuselage (2), and the inlet flap (7) is configured such in its closed position a surface of the inlet flap (7) is substantially flush with the tailcone fuselage (2). The invention reduce drag by improving the aerodynamics of the tailcone fuselage boundary layer ingestion, as well as the aerodynamics of the turbomachine air intake.
