Abstract

LE DISPOSITIF EST CONCU POUR ABSORBER L'ENERGIE CINETIQUE SUIVANT UNE LOI PREDETERMINEE PAR DEFORMATION PROGRESSIVE DE LA SECTION D'UNE EPROUVETTE TUBULAIRE SOUS L'ACTION D'UN ORGANE DE PRESSION MOBILE LE LONG DE CETTE EPROUVETTE. POUR ABSORBER L'ENERGIE CINETIQUE RESULTANT DU MOUVEMENT RELATIF ENTRE DEUX CORPS, L'EPROUVETTE 5 EST RELIEE, PAR EXEMPLE PAR UNE ROTULE 6, A L'UN DES DEUX CORPS TANDIS QUE L'ORGANE DE PRESSION, PAR EXEMPLE SOUS LA FORME D'UN CHARIOT 2 A ROULEAUX 7, 8, EST SOLIDAIRE D'UN TUBE 1 RELIE, PAR EXEMPLE PAR UNE ROTULE 3, A L'AUTRE CORPS. DIFFERENTS MOYENS LE LONG DE L'EPROUVETTE PERMETTENT DE FAIRE VARIER SA RESISTANCE AU COURS DE SA DEFORMATION. LE DISPOSITIF S'APPLIQUE A LA PROTECTION D'UN PILOTE OU PASSAGER D'UN HELICOPTERE A L'ATTERRISSAGE.
