Aircraft wings

An aircraft wing comprising an aerofoil structure, the aerofoil structure comprising:

• a load-carrying member;
• a leading-edge structure forming a leading-edge part of an aerodynamic surface of the aerofoil structure, fixedly mounted to the load-carrying member;
• a trailing-edge structure forming a trailing edge part of the aerodynamic surface, fixedly mounted to the load-carrying member;
• wherein:
• the load-carrying member comprises a beam formed by a first chordwise member, a second chordwise member, and a diagonal member connected in series;
• the first chordwise member extends from the trailing-edge structure to the leading-edge structure;
• the second chordwise member extends from the trailing-edge structure to the leading-edge structure, the second chordwise member being spaced apart from the first chordwise member in a spanwise direction;
• the diagonal member extends both in the spanwise direction and in a chordwise direction from the trailing-edge structure to the leading-edge structure and connects the first chordwise member and the second chordwise member;
• the load-carrying member has stiffness properties selected such that the load-carrying member twists in a predefined manner in response to bending of the load-carrying member;
• and
• the aerofoil structure further comprises a first actuator which is fixedly mounted to the load-carrying member and which extends to bend the load-carrying member to thereby cause the load-carrying member to twist.
