Abstract: A leading edge structure for an aerodynamic surface of an aircraft with an outer wall part curved in a streamlined manner around an interior compartment and having an inner surface pointing toward the interior compartment and an outer surface provided for contact with the external surrounding flow. The outer wall part has a first outer wall section extending from a leading edge point in an incident flow direction in a convexly curved manner in the direction of a first side. The outer wall part has a second outer wall section which extends from the leading edge point in the incident flow direction in a convexly curved in the direction of a second side. An inner wall part is arranged in the interior compartment opposite the inner surface of the outer wall part and extends from the first outer wall section to the second outer wall section.

Abstract: Disclosed is a taper bolt connection including a taper bolt received in a taper bush, a fastening nut and a washer, the taper bush having a continuous longitudinal slot, and the taper bush being capable of being spread open uniformly in the radial direction by means of a fastening nut screwable onto the taper bolt. Since the taper bolt and/or the taper bush have/has, at least in regions, an at least Teflon-containing coating, tribochemical processes between the taper bush wedge surface and the taper bolt wedge surface are largely avoided, so that the taper bolt connection can be released again without great effort even after a long period of connection. Furthermore disclosed is the use of the taper bolt connection for connecting a rudder unit to a carrying structure of a fuselage cell of an aircraft.
