PROBLEM TO BE SOLVED: To provide a retractable infill panel for sealing a gap between a fixed leading edge structure of an aircraft wing and a movable high-lift device, in particular for preventing ingress of fire or debris.SOLUTION: A fixed structure 10 has a spar, a forward part which provides a foremost edge of an aircraft wing, and a lower part which provides a lower surface of the aircraft wing. A high-lift device 30 is downwardly movable relative to the fixed structure from a stowed configuration to a deployed configuration. The high-lift device has a forward part which provides a foremost edge of the aircraft wing, and a lower part which provides a lower surface of the aircraft wing. Downward movement of the high-lift device causes progressive opening of a lateral gap between the lower part of the high-lift device and the lower part of the fixed structure. A retractable infill panel 50 is arranged to progressively extend from a retracted configuration to an extended configuration to fill the lateral gap. |
