Abstract

Method of protecting a part of a surface of an aircraft against contamination with insect residues and / or against icing, comprising the following steps: b) coating the part of the surface to be protected with a coating that can, within a period of ≰3 hours from take-off of the aircraft and in normal flying conditions, reduce the adhesion to the part of the surface to be protected until detachment occurs on the basis of (i) temperature change and / or (ii) UV radiation and / or (iii) addition of a decomposing component and / or (iv) difference in air humidity, b) exposing the part of the surface to be protected to (i) a temperature change and / or (ii) UV irradiation (iii) and / or addition of a decomposing component and / or (iv) a difference in air humidity, so that the coating together with any contaminants and / or icing thereon detaches.

Description

technical field [0001] The present invention relates to a method for protecting the surface of a part of an aircraft from contamination by insect residues and / or from icing by providing a layer which is exfoliated from the surface of the aircraft and thereby removes possible contamination and / or freeze. The invention also relates to a corresponding coated aircraft, a device for applying a corresponding layer on an aircraft, and a correspondingly arranged coating for protecting a surface of an aircraft from contamination by insect residues and / or from icing Use, and the use of a coating device for coating a part of the surface of an aircraft with a correspondingly arranged coating. Background technique [0002] For economical and ecological reasons, it is desirable for an aircraft to consume as little fuel as possible. The current generation of aircraft typically run on jet fuel, and from this we assume that jet fuel based fuels will also be the main fuel source in the futu...
