Abstract: An aircraft landing flap includes a flap member having an abrasion-resistant coating coated on an abrasion region exposed to mechanical rubbing contacts with an aircraft spoiler. The coating comprises a polyurethane matrix based on aliphatic components and fillers embedded in the polyurethane matrix so as to increase resistance to abrasion.

Abstract: The use of a lacquer is described, comprising a polyurethane matrix based on aliphatic components and fillers which are embedded in the polyurethane matrix and increase the resistance to abrasion as an abrasion-resistant coating of (a) aircraft landing flaps 2 in the contact region with the spoilers 4 or (b) in the abrasion region of the cargo doors or (c) in the abrasion region of other aircraft parts mechanically rubbing on one another during operation. Corresponding landing flaps and lacquers are also described.

Abstract: Disclosed is a device for removing sealing material on components of an aircraft having a drive unit and a tool connected to the drive unit. The drive unit can, for example, be realized with the aid of an electric motor and an eccentric. Accordingly, the tool, which can be actuated by hand, is set in a quickly oscillating to and fro movement parallel to a longitudinal axis of the tool by means of the drive unit, as a result of which the force to be applied by a user in order to lift off or tear away the sealing material from a joint is substantially reduced. An underside 22 of the tool forms with a wedge face a sharp cutting edge for detaching the slug of the sealing material from the base of the joint. The wedge face can be flat, concave or arbitrarily generally curved in one or two spatial dimensions.
