SYSTEM AND METHOD OF MEASUREMENT OF FATIGUE FOR MECHANICAL DETAILS OF AIRCRAFT AND AIRCRAFT MAINTENANCE METHOD

摘要

FIELD: instrumentation.;SUBSTANCE: invention relates to the system and the method of measurement of fatigue for mechanical details of aircrafts, for example of planes, and also to the aircraft maintenance method. The system of measurement of general fatigue damage of the detail (7, 8, P, P', 9a, 6') of the aircraft exposed to mechanical tensions, containing a set of tension sensors (Ci) installed on the detail (7, 8, P, P', 9a, 6'), while each sensor is implemented with a possibility of detection of pre-set threshold (S (Ci)) of mechanical tension and with a possibility of sending of the signal (Si) of data witnessing on excess of this threshold (S (Ci)); the system contains the devices (11) for registration of these data, and the sensors (Ci) are implemented with a possibility of detection of mutually different and discrete thresholds (S (Ci)) that allows on the basis of the data registered by system to calculate the estimated fatigue of the detail (7, 8, P, P', 9a, 6') connected with the considered mechanical tension.;EFFECT: optimisation of inspections of details.;10 cl, 4 dwg, 1 tbl
