ESTIMATION OF A CRITERION OF LOAD TO WHICH A STRUCTURAL COMPONENT OF AN AIRCRAFT IS SUBJECTED, AND ASSISTANCE FOR THE DETECTION OF A SO-CALLED 'HARD' LANDING BY VIRTUE OF SUCH A CRITERION

摘要

The present invention relates to methods and systems forestimating a loading criterion relating to the load (C) experienced by astructural component (100, 102, 104) of an aircraft (10), and assistancewith detecting a so-called "hard" landing. These methods involvemeasuring (50) parameters of said aircraft and calculating (54) at least oneloading criterion for the loading of said structural component using at leastone neural network (36) receiving said parameters as input. Assistancewith detecting a hard landing then requires the determining (72, 76) of atime (t0, t-i) of impact (14, 16) of said aircraft on a landing strip (12)fromsaid measured parameters, then estimating (74, 78) a plurality of saidparameters at said determined time of impact so as to calculate (54) the atleast one loading criterion relating to the loading of the structuralcomponent.
