Abstract

L'invention a pour objet un dispositif mécanique de détection des atterrissages durs pour aéronef. Le dispositif comprend en combinaison avec des moyens de mémorisation 9, des moyens de détection de la seule composante verticale de l'accélération, ces moyens comportant un seuil de déclenchement et étant composés d'une pendule de torsion 2 et de moyens élastiques 7 réalisant le seuil de déclenchement des moyens de détection. La disposition selon l'invention est applicable à tous les aéronefs, à atterrissages longs, courts ou même verticaux.
