Abstract

L'INVENTION CONCERNE UN CAPTEUR DE MESURE D'EFFORTS PERMETTANT, D'UNE PART, DE MESURER UN COUPLE DE TORSION AUTOUR D'UN PREMIER AXE AINSI QUE LE MOMENT D'UNE FORCE PAR RAPPORT A UN DEUXIEME AXE PERPENDICULAIRE AU PREMIER. CE CAPTEUR COMPREND UN TUBE DE TORSION COAXIALE AU SUSDIT PREMIER AXE ET UN ELEMENT ELASTIQUE TRAVAILLANT A LA FLEXION AUTOUR D'UN SECOND AXE PERPENDICULAIRE AU PREMIER. CE CAPTEUR COMPREND UN TUBE DE TORSION COAXIALE AU SUSDIT PREMIER AXE ET UN ELEMENT ELASTIQUE TRAVAILLANT A LA FLEXION AUTOUR D'UN SECOND AXE PERPENDICULAIRE AU PREMIER, ET FIXEMENT SOLIDAIRE A L'UNE DE SES EXTREMITES, DU TUBE DE TORSION. LES DEUX EXTREMITES NON SOLIDAIRES DE CES DEUX CORPS D'EPREUVE SONT RESPECTIVEMENT RELIEES, D'UNE PART, A UN ELEMENT RESISTANT ET, D'AUTRE PART, A L'ELEMENT MOTEUR. UN TRANSDUCTEUR TEL QU'UN BARREAU SEMI-CRISTALLIN PIEZO-RESISTIF EST ASSOCIE A CHACUN DE CES DEUX CORPS D'EPREUVE. CE CAPTEUR PEUT S'INTEGRER DANS LE MOYEU DU MANCHE DE PILOTAGE D'UN AERODYNE.
