An airfoil, a flap mechanism and an associated method are provided to controllably actuate a flap positioned proximate the trailing edge of an airfoil body. The flap mechanism includes a carrier beam hingedly connected to an airfoil body and also pivotally connected to a flap proximate the trailing edge of the airfoil body. The flap mechanism further includes an actuator, a first plurality of links and a second plurality of links. The first plurality of links is operably connected to the airfoil body, the actuator and the carrier beam. The first plurality of links causes the carrier beam to be rotated with respect to the airfoil body in response to actuation by the actuator. The second plurality of links is responsive to rotation of the carrier beam with respect to the airfoil body. The second plurality of links causes the flap to be rotated with respect to the carrier beam.

A wing for an aircraft, including a main wing, and a leading edge high lift assembly including a high lift body, and a connection assembly connecting the high lift body to the main wing such that the high lift body is movable relative to the main wing between a stowed position and a deployed position. The connection assembly includes at least one rotation element mounted to the high lift body and mounted to the main wing rotatably about an axis of rotation. The high lift body includes a rigid portion and a flexible skin portion. The rigid portion is mounted to the rotation element. The flexible skin portion is connected to a leading edge portion of an upper skin panel of the main wing and is connected to the rigid portion of the high lift body The flexible skin portion is configured to be deformed between a stowed deformation state and a deployed deformation state, when the high lift body is moved between the stowed position and the deployed position.

A flap support mechanism includes a carrier beam on which a flap is mounted. The carrier beam is rotatably mounted at a fixed rotational axis and has a pair of flanges, each flange having an aperture, and a channel extending aft from the pair of flanges. A fuse pin is received through the aperture in each flange. A coupler link is attached to an actuator at a first end and pivotally engaged to the carrier beam by the fuse pin. Extension of the coupler link by the actuator rotates the carrier beam from a stowed position to a deployed position. Responsive to a moment induced on the flap and carrier beam by a ground contact load, the fuse pin is frangible to shear releasing the coupler link to translate into the channel.

An aerodynamic structure incorporated in an aircraft control surface (10) provides a spar (16) extending along at least a portion of the control surface in a direction and the spar includes a plurality of bends along the direction of extension along the control surface to provide space to accommodate actuator fittings or other structural or operational requirements.

An aerodynamic structure comprising an aerodynamic surface. The aerodynamic surface is formed by a first part of the aerodynamic structure; a second part of the aerodynamic structure; and a sealed gap between the first part and the second part. The sealed gap contains a sealant material and a support material.

An aircraft flight control system includes a first actuator attached to a wing main body, a horn arm configured to transmit an output of the first actuator to a control surface, and a second actuator that is a rotary actuator and attached to the control surface. At least one of the first actuator and the second actuator is an electromechanical actuator (EMA). A first end of the horn arm is coupled to an output terminal of the first actuator, and a second end of the horn arm is fixed to an output terminal of the second actuator. The second actuator is attached to the control surface such that a turning axis of the output terminal is parallel to or coincides with a fulcrum axis (hinge line) of the control surface.

The invention provides an aircraft with a trimmable horizontal stabilizer (13) that not requires a cut-out in resistant areas of the rear fuselage and that occupies less space that in conventional horizontal stabilizers. The rear fuselage (5) comprises at least a first section (9) having a resistant fuselage and a second section (11), aft of the first section, having a non-resistant fuselage (i.e. a fairing). The load-bearing structure (30) of the horizontal stabilizer and the trimming actuator (50) are disposed inside said second section (11). The pivot element (41) is mounted on its forward side and coupled to the first section (9) of the rear fuselage. The connection fitting (21) is mounted on its rearward side and the trimming actuator (50) is disposed so that it exerts a force in the direction of the Z-axis of the aircraft on the connection fitting (21) during a trimming operation.
