Seal for aircraft wing

A seal system for use in a wing comprising:

• a fixed aerofoil,
• a resilient seal plate fixed to the aerofoil,
• a control surface moveable relative to the aerofoil;
• and
• a seal attached to the seal plate and arranged to seal between the seal plate and the control surface, the seal comprising:
• a first seal portion configured to provide a seal between a free edge of the seal plate and an edge of the control surface and further configured to transmit a first bending moment from the control surface to the seal plate in a first position of the control surface relative to the aerofoil;
• a second seal portion configured to provide a seal between the free edge of the seal plate and the edge of the control surface and further configured to transmit a second bending moment from the control surface to the seal plate in a second position of the control surface relative to the aerofoil;
• wherein the seal comprises a transition portion between the first and second seal portions arranged to sealingly engage with the edge of the control surface between the first and second positions of the control surface;
• wherein the first and the second seal portions are substantially convex, and the transition portion is concave, with respect to the edge of the control surface;
• and,
• wherein the first and second seal portions are relatively configured such that the second bending moment is substantially greater than the first bending moment.
