Number of tire landings counting method for wheel of airplane, involves detecting rotation frequency of tire greater than given rotation frequency, incrementing counter, and detecting crossing of given rotation frequency by tire

摘要

The method involves equipping a measurement device e.g. sensor such as accelerometer, in a tire, where the device measures a rotation frequency of the tire. Rotation of the tire is detected, and the rotation frequency of the tire is determined. A rotation frequency greater than a given rotation frequency is detected, where the given rotation frequency corresponds to a speed of aircraft greater than a usual ground displacement speed (Vs), outside of take-off sequence (S2) and landing sequence (S3). A counter is incremented. Crossing of the given rotation frequency by the tire is detected. An independent claim is also included for a device for counting a number of landings of a tire of aircraft for use in rubber patch, comprising a sensor.
