METHOD OF CONTROLLING AIRCRAFT STRUCTURE STATE AND DEVICE TO THIS END Russian patent published in 2015 - IPC G01M17/02 G01S13/88 B64C25/26 

FIELD: aircraft engineering.

SUBSTANCE: rpm of landing gear wheels struts is measured at takeoff and landing. Run of every said wheel tire is defined for current takeoff-landing interval. Said run is summed with available value to define the run of every tire from the start of operation. Current take-off-landing is registered and to add the last takeoff-landing of every tire to available data. The number of take-off-landing from the start of operation is defined to record the data on said number of take-off-landing for every tire and its run from the start of operation in onboard data storage. In case said number is larger than preset magnitude, aircraft crew is adequately informed about said effect. In compliance with this invention aircraft landing gear wheels are provided with rpm transducers with their outputs connected via second set of inputs of third element OR, first amplifier unit, first ADC unit, first unit of pulse generators and first unit of counters with the sixth set of inputs of data collection device.

EFFECT: perfected monitoring at run, take-off and landing.
