Abstract

Un système embarqué pour déterminer instantanément les données de masse et centrage dun aéronef de manière simple, fiable et précise, et nécessitant un étalonnage minimal. Le système comprend une mémoire pour stocker les données de frottement déterminées précédemment des jambes amortisseuses des trains datterrissage de laéronef, des capteurs pour détecter les pressions dans les jambes amortisseuses, les charges verticales exercées par les trains datterrissage sur laéronef et lassiette de laéronef par rapport à lhorizontale durant son chargement ou son déchargement, et un ordinateur pour calculer la charge verticale dans chacun des trains d'atterrissage à partir des données de frottement d'étalonnage stockées et les pressions des jambes amortisseuses, les charges verticales des trains d'atterrissage et l'assiette de l'aéronef détectée durant le chargement ou le déchargement. Lordinateur calcule alors le poids brut de laéronef et lemplacement de son centre de gravité au moyen des charges verticales calculées dans les trains datterrissage.
