摘要： A method of retrofitting a wing of a fixed wing aircraft. The method including the steps of providing an existing aircraft wing (20) with a main fixed wing portion; the main fixed wing portion having a tip end (34) and an existing movable flight control surface (30) connected adjacent the tip end. The existing movable flight control surface (30) is then removed from the main fixed wing portion, and a wing tip device (40a) and movable flight control surface (30a) are selected as a pair to replace the existing movable flight control surface, with the selected movable flight control surface (30a) having an aerodynamic surface of different shape to the shape of the flight control surface (30) removed from the wing. The selected wing tip device and movable flight control surface are then fitted to the main fixed wing portion.

摘要： An aircraft (1002, see Fig. 3b) comprising a wing (1001, see Fig. 3b), having a fixed wing (1005) with a wing tip device (1003) moveably mounted at the outer end thereof. The wing tip device (1003) is moveable between: a flight configuration; and a ground configuration about an axis of rotation. The wing tip device (1003) and the fixed wing (1005) meet along an interfacing cut line (1035, see Fig. 4). The interfacing cut line (1035, see Fig. 4) comprises curved section (1039) centred on the axis of rotation (1011), the radius of the curved section constantly increasing as the cut line passes around the axis (for example a spiral shape).

摘要： The present invention relates to an actuating system for a wing arrangement (3) for an aircraft (1). The arrangement (3) includes a wing (9) comprising a base section (11) having a first end portion (11a) adapted to be secured to the fuselage (5) of an aircraft (1) and an opposite second end portion (11b), and a tip section (13) having a third end portion (13a) and an opposite fourth end portion (13b), wherein the third end portion (13a) is pivotably connected to the second end portion (11b) such that the tip section (13) is pivotable about a pivot axis (17) between a deployed position and a stowed position in which the spanwise length of the wing (9) is smaller than in the deployed position. The actuating system (21) comprises an actuating arrangement (23) which comprises an actuator (25), a first coupling part (29) and a second coupling part (31). The first coupling part (29) is adapted to be coupled to the base section (11), the second coupling part (31) is adapted to be coupled to the tip section (13) and the actuator (25) is operable to move the second coupling part (31) with respect to the first coupling part (29) between a first position and a second position, such that when the first coupling part (29) is coupled to the base section (11) and the second coupling part (31) is coupled to the tip section (13) the actuating arrangement (23) is operable to selectively move, by operating the actuator (25), the tip section (13) between the deployed position and the stowed position. In the first position of the second coupling part (31) the tip section (13) is in the deployed position, and in the second position of the second coupling part (31) the tip section (13) is in the stowed position. The actuating system (21) further comprises a heating arrangement (33) which is positioned and adapted to be operable to heat at least one portion of the actuating arrangement (23) such that at least for ambient temperatures below a predetermined temperature the required work to be effected by the actuator (25) when moving the second coupling part (31) between the first position and the second position is lower than without heating the at least one portion.

摘要： Systems and methods described herein provide for the control of airflow over a vertical control surface of an aircraft to enhance the forces produced by the surface. According to one aspect of the disclosure provided herein, the vertical control surface of the aircraft is engaged by active flow control actuators that interact with the ambient airflow to alter one or more characteristics of the airflow. An actuator control system detects a flow control event, and in response, activates the active flow control actuators to alter the airflow. According to various aspects, the flow control event is associated with a separation of the airflow, which is corrected through the activation of the appropriate active flow control actuators, increasing the forces produced by the vertical control surface of the aircraft.
