Title
(FR) ARCHITECTURE D'UN SYSTEME PROPULSIF D'UN HELICOPTERE MULTI-MOTEUR ET HELICOPTERE CORRESPONDANT
Abstract
(FR)
L'invention concerne une architecture d'un système propulsif d'un hélicoptère multi-moteur comprenant des turbomoteurs (1, 2) reliés à une boite (3) de transmission de puissance, et un réseau (7) de bord basse tension continue destiné à alimenter en vol des équipements de l'hélicoptère, caractérisée en ce qu'elle comprend : un turbomoteur (1) hybride apte à fonctionner dans au moins un régime de veille au cours d'un vol stabilisé de l'hélicoptère ; un pack (20) électrotechnique de redémarrage rapide dudit turbomoteur hybride pour le sortir dudit régime de veille et atteindre un régime dans lequel il fournit de la puissance mécanique, ledit pack (20) de redémarrage étant relié audit réseau (7) de bord ; et au moins deux sources (4, 16, 18) d'alimentation électrique dudit réseau (7) de bord.
