Abstract (en)
[origin: WO2018115675A1] The present invention relates to a method for determining the condition of an aircraft tyre and, more specifically, to a method for determining the wear condition thereof, allowing the residual lifetime and, more specifically, the number of residual landings, to be predicted for said tyre. A method for determining the condition of an aircraft tyre, said tyre comprising a tyre tread having at least one circumferential rib comprising at least one wear indicator, said method for determining condition comprising: - a step of detecting a first pattern of the position of the wear indicator, which is intended to identify the position of said wear indicator in the tyre tread; a step of detecting a second pattern of the condition of the wear indicator, which is intended to determine the wear condition of the relevant circumferential rib at a given instant; - a step of analysing the first pattern of the position and the second pattern of the condition of the wear indicator, through a comparison with reference patterns, and of determining the wear condition of the circumferential rib at a given instant; and - a step of rendering information relating to the condition of the tyre.
