Abstract: A method for estimating a loading criterion relating to the load experienced by a structural component of an aircraft, and assistance with detecting a so-called “hard” landing. The method includes measuring parameters of the aircraft and calculating at least one loading criterion for the loading of the structural component using at least one neural network receiving the parameters as input. Assistance with detecting a hard landing then includes determining of a time of impact of the aircraft on a landing strip from the measured parameters, then estimating a plurality of the parameters at the determined time of impact so as to calculate the at least one loading criterion relating to the loading of the structural component.

Abstract: The present invention relates to methods and systems for estimating a loading criterion relating to the load (C) experienced by a structural component (100, 102, 104) of an aircraft (10), and assistance with detecting a so-called “hard” landing. These methods involve measuring (50) parameters of said aircraft and calculating (54) at least one loading criterion for the loading of said structural component using at least one neural network (36) receiving said parameters as input. Assistance with detecting a hard landing then requires the determining (72, 76) of a time (t0, t-i) of impact (14, 16) of said aircraft on a landing strip (12) from said measured parameters, then estimating (74, 78) a plurality of said parameters at said determined time of impact so as to calculate (54) the at least one loading criterion relating to the loading of the structural component.

Abstract: A mobile test rig for tires, composed of a self-driven platform capable of following rectilinear and circular trajectories and including: a test instrument module for a wheel-tire assembly to be tested that permits the assembly to be orientated in all directions, to lean the assembly and apply a vertical effort to the assembly, first swivelling axles, equipped with suspensions and driving wheels, a processing unit associated to a memory, and a control of the test cycle permitting orientation of the assembly to be controlled, as well as a load applied to the assembly.
