Abstract

L'invention concerne un procédé de détection de défauts d'une structure aéronautique (STR), comprenant les étapes suivantes: • on dispose sur la structure (STR) un maillage constitué d'une pluralité de mailles (M) et défini par une pluralité de transducteurs (100), chaque transducteur étant commandé au moins entre : ○ un mode d'émission dans lequel il est apte à émettre un signal d'excitation vers les autres transducteurs (100), ○ et un mode de réception dans lequel il est apte à recevoir un signal de réception émis par un autre transducteur (100), les signaux d'excitation et de réception étant aptes à se propager à travers la structure (STR), • on extrait, en fonction des signaux d'excitation et de réception, une signature (S) pour chacune des mailles (M), • on compare les signatures (S) entre elles pour identifier parmi les mailles (M) au moins une maille comme localisant un défaut de la structure (STR), appelée maille défaillante, lorsque la signature (S) de cette maille (M) est différente de plusieurs autres signatures (S) de plusieurs autres mailles (M).
