End seal device for a high-lift device of an aircraft

Abstract:

An end seal device for a high-lift device on an airfoil leading edge of an airfoil includes an end seal body configured to be coupled to the airfoil and having a seal body spanwise portion and a seal end. The end seal body is configured to be in a seal extended position when the high-lift device is in a device extended position. The seal body spanwise portion is disposed adjacent to the aircraft body or the airfoil leading edge and the seal end is disposed adjacent to a device end of the high-lift device when the end seal body is in the seal extended position and the high-lift device is in the device extended position. The end seal body in the seal extended position fills a discontinuity otherwise occurring between the device end and the aircraft body or airfoil leading edge if the end seal body were omitted.
