Patent number: 5511430
Abstract: The invention relates to a method for detecting that the design loads of an aircraft have been exceeded during landing.According to the invention:--in a preliminary step:the load criteria (C1, C2, . . . , Cp) are defined; andthe laws of variation of the allowable values (C1ad, C2ad, . . . , Cpad) of these load criteria (C1, C2, . . . , Cp) are determined, as a function of input parameters (P1, P2, . . . , Pn); and--at the moment of landing:the values of the said input parameters (P1, P2, . . . , Pn) and of the said load criteria (C1, C2, . . . , Cp) are measured;the allowable values (C1ad, C2ad, . . . , Cpad) of the said load criteria (C1, C2, . . . , Cp) are calculated;for each of the said load criteria (C1, C2, . . . , Cp), the measured effective value (C1m, C2m, . . . , Cpm) is compared with the calculated allowable value (C1ad, C2ad, . . . , Cpad); andit is determined whether a structural inspection must be carried out.
