Abstract
L'INVENTION CONCERNE L'INDUSTRIE AERONAUTIQUE. L'HELICOPTERE SUIVANT L'INVENTION COMPREND DES MOYENS POUR ABSORBER SELECTIVEMENT L'ENERGIE RESTITUEE PAR LE ROTOR PRINCIPAL DE SUSTENTATION PENDANT LES PERIODES DE DECELERATIONS. DEUX ROTORS DE QUEUE 13 SONT MONTES A L'ARRIERE DU FUSELAGE 11 DE L'HELICOPTERE ET UNE COMMANDE DE PAS DIFFERENTIELLE PERMET DE REGLER SEPAREMENT LES DEUX ROTORS POUR QU'ILS FOURNISSENT DES POUSSEES LATERALES OPPOSEES. L'INVENTION PERMET DE RACCOURCIR LA DISTANCE D'ARRET DES HELICOPTERES A GRANDE VITESSE.
