Aerodynamic drag associated with a flap hinge assembly (30) used to pivotally mount a flap (17) to the trailing edge (22) of an aircraft (10) wing (14) can be reduced when the cross-sectional area of the hinge fairing (24) which surrounds the flap hinge assembly is reduced in size. The reduction in cross-sectional area of the hinge fairing is enabled when the flap hinge assembly attachment footprint to the underside of the flap box is also reduced. The flap hinge assembly has an internal support rib (66) positioned between spars of the flap box structure internal to the skin, a hinge fitting (44) exhibiting an actuation point (50) and a hinge point (52) positioned proximate a front spar (60) of the flap box structure external to the skin, and a link (68) passing through an aperture (70) in the lower skin (46) of the flap and coupling the internal support rib to the hinge fitting.

Systems and methods according to one or more embodiments are provided for a Krueger flap (104) assembly with dual Krueger seal assemblies (310,312). In certain embodiments, the dual Krueger seal assemblies (310,312) may seal a space between a Krueger flap main body (104) and an aircraft engine (108). Further seals may be provided to seal any gaps between the dual Krueger seal assemblies (310,312). In certain embodiments, one or both of the dual Krueger seal assemblies (310,312) may include centrally grounded springs (418a,418b,420a,420b). The dual Krueger seal assemblies may include a plurality of springs supporting each Krueger seal assembly.
摘要:
A system and method for reducing aerodynamic drag is disclosed. A compression seal is attached to the inboard edges of the stabilizer and elevators of an airplane. The seal blocks airflow in a gap located between these inboard edges and a fuselage. The shape of the compression seal changes as the shape of the gap changes due to movement of the stabilizer and elevators during flight to effectively block airflow through the gap during flight. By blocking the airflow, the seal reduces the aerodynamic drag of the airplane.

A wing (130) includes a trailing edge, which may include a moveable flight control surface (230), and a divergent trailing edge device (240) slideable along an aft surface of the trailing edge or moveable flight control surface (230) between a stowed position and a fully deployed position. The divergent trailing edge device (240) is located entirely within the trailing edge or moveable flight control surface (230) when stowed, and it increases lift over drag of the wing (130) when deployed.

Concepts and technologies described herein provide for a low noise aircraft wing slat system. According to one aspect of the disclosure provided herein, a cove-filled wing slat is used in conjunction with a moveable leading edge element of an aircraft wing to provide a high lift system. The moveable leading edge element may include a one-piece or two-piece panel that retracts within the aircraft wing to accommodate the cove-filled slat in the stowed position. Upon deployment of the cove-filled slat, the moveable leading edge element deploys outward to create a continuous outer mold line shape with the wing.
