Abstract: An assembly comprises a wing and a pylon fairing extending from the wing at a pylon location. The pylon fairing has an aerodynamic profile defining a fairing trailing edge. The pylon fairing has an upper section extending from the wing and a lower section including a shelf. The aerodynamic profile of the upper section is cambered toward the root of the wing. The aerodynamic profile of at least part of the lower section is symmetrical. The fairing trailing edge in the upper section extends axially rearward of a trailing edge of the wing at the pylon location. In addition or alternately, a distance between the fairing trailing edge in the upper section and a trailing edge of the wing at the pylon location has a value corresponding to at most 30% of a local chord of the wing at the pylon location.

Abstract: An outlet door is provided for covering an outlet defining an outlet area in a skin (24) of an aircraft component to exhaust a flow of heated air to an outside of the aircraft. The outlet door includes a body defining a door area and extending between a leading edge and a trailing edge and a linkage (38) connecting the body to the aircraft, permitting the body to transition between at least one of an open position and a closed position. In the closed position, the body at least partially occupies the outlet area. In the open position, the body forms an angle with the skin of the aircraft. The leading edge of the body and the skin of the aircraft define a separation (202) therebetween when the body is in the open position. The separation defines and air flow for mixing cold air with the flow of heated air.
