METHOD TO CONTROL CONDITION OF AIRCRAFT STRUCTURE AND DEVICE FOR ITS REALISATION Russian patent published in 2013 - IPC G01M17/00 

FIELD: measurement equipment.

SUBSTANCE: during movement of an aircraft (AC) on an airfield to the moment of takeoff and from the moment of landing to stop of the AC they measure temperature and pressure in each chassis tyre, current values of pressure and temperature are compared in each tyre with the specified value, current values of pressure and temperature are compared in m doubled tyres of chassis stands to each other, information on pressure and temperature is recorded in each tyre in a board information tank. If the difference of pressure or temperature values in each tyre and in m doubled tyres is by a value more than the specified one, and the aircraft crew is accordingly informed. The device comprises two detection devices installed on board of the AC, an information collection device, a on-board device, a unit of emergency condition alarm, a power supply unit, a sensor unit, an alarm indicator. The sensor unit comprises a unit of end switches of the AC chassis, a motion sensor, an altitude metre. The device additionally includes information sensors, one for each chassis wheel.

EFFECT: higher quality of AC chassis tyre technical condition monitoring.
