The present disclosure relates to a structural component of an aircraft wing body and an aircraft including the structural component. According to an aspect of the present disclosure, a structural component of an aircraft wing body is provided. The structural component includes a body part and a profile. The body part includes an edge portion formed by end portions of a first skin and a second skin of the body part superposed together. The profile is attached to the edge portion. The profile has an outer profile conforming to an outer profile of the body part such that the structural component, as a whole, exhibits an aerodynamic outer profile after the profile is attached to the edge portion. The profile is attached to the edge portion via a plurality of separate intermediate members or by contacting the edge portion.

In one embodiment, an apparatus includes a first deflector configured to couple to a shaft of an aircraft. The first deflector may form part of a top surface of the aircraft when in a first closed position. The apparatus may further include a second deflector configured to couple to the shaft and form part of a bottom surface of the aircraft when in a second closed position. The first deflector and the second deflector may be configured to be positioned at a junction of a body of the aircraft and a wing of the aircraft. The first deflector and the second deflector may be configured to simultaneously pivot from the closed positions to respective first and second open positions upon actuation of the shaft.

An airfoil system is provided that includes an airfoil. This airfoil includes a first exterior surface, a second exterior surface, a first airfoil segment and a second airfoil segment. The airfoil extends widthwise between the first exterior surface and the second exterior surface. The first airfoil segment includes first composite material and a receptacle. A base of the receptacle is embedded within the first composite material. The second airfoil segment includes second composite material and a key. A base of the key is embedded within the second composite material. The key is mated with the receptacle thereby attaching the second airfoil segment to the first airfoil segment.

A method may be present for securing a strip in a structure. A first surface of the strip may be masked with a first tape. A surface of the structure may be masked with a second tape, the surface of the structure defining a desired shape. A sealant may be applied in a groove in the structure. The strip may be positioned in the surface such that a second surface of the strip contacts the sealant; and a caul plate may be pressed against the first surface of the strip, the caul plate including a set of ribs that contact the fairing strip, and the plurality of ribs defining a shape that substantially matches the shape of the surface of the structure. Pressing the caul plate against the first surface of the strip may cause sealant to pass between the set of ribs onto the tapes.

A leading edge structure for a flow control system of an aircraft is disclosed having a leading edge panel that surrounds a plenum, wherein the leading edge panel has a first side portion, a second side portion opposite the first side portion, an inner surface facing the plenum and an outer surface in contact with an ambient flow, and wherein the leading edge panel comprises a plurality of micro pores forming a fluid connection between the plenum and the ambient flow, wherein the plenum is connected to an air outlet arrangement configured for causing an underpressure in the plenum, so that air from the ambient flow is drawn through the micro pores into the plenum and from there discharged through the air outlet arrangement into the ambient flow.

A securement assembly for securing a vertical tail fin assembly to an aircraft includes a first lug member secured to the vertical tail fin assembly. The securement assembly further includes a first clevis member. The first clevis member includes a first end portion of the first clevis member is engaged to the first lug member. A second end portion of the first clevis member is secured to a first fuselage frame constructed of a composite material with a first fastener which extends through the second end portion and the first fuselage frame in a first direction transverse to the first fuselage frame.

An aircraft having a fuselage terminating in an empennage with a tail extending upwardly from the empennage. An engine strut extends from the empennage with an engine mounted to the engine strut and a moveable control surface provided on the engine strut.

Embodiments of the present disclosure include a curved planar wingtip for a straight wing and a curved planar wingtip for a swept wing of an aircraft. The curved planar wingtips include a member that extends from the end of the wing in a direction aft of the wing trailing edge while remaining substantially planar with the wing. The curved planar wingtips curve continuously from leading and trailing edges of the wing to form a tip located aft of the wing. Other embodiments of the curved planar wingtip are configured for a horizontal or vertical tail. Yet another embodiment includes a curved wingtip that extends aft of a trailing edge of the wing by a distance greater than the curved wingtip extends above a top surface of the wing.
