Title (EN) AUXILIARY SYSTEM FOR DRIVING A SHAFT OF A HELICOPTER PROPULSION SYSTEM
(FR) SYSTEME AUXILIAIRE D'ENTRAINEMENT D'UN ARBRE D'UN SYSTEME PROPULSIF D'UN HELICOPTERE
Abstract: front page image
(EN)The invention relates to an auxiliary system for mechanically driving a relay shaft (8) of a helicopter propulsion system, comprising: a hydraulic motor (7), mechanically connected to said relay shaft (8); a hydraulic circuit (10) for supplying a pressurised liquid to said hydraulic motor (7); a controlled, fast-opening hydraulic valve (11) arranged on the hydraulic circuit (10); a pyro-hydraulic storage unit (9) driven by a control unit (12) and connected to said hydraulic valve (11), said pyro-hydraulic storage unit (9) comprising: an enclosure (20) including a piston (16) that defines a main compartment (17) having at least one solid propellant cartridge (19) and a compartment (18) for a liquid supply; an ignition charge (25) connected to said main compartment (17) and suitable for initiating the combustion of at least one solid propellant cartridge (19) upon receiving a command from said control unit (12)
(FR)L'invention concerne un système auxiliaire d'entrainement mécanique d'un arbre (8) relais d'un système propulsif d'un hélicoptère comprenant : un moteur (7) hydraulique relié mécaniquement audit arbre (8) relais; un circuit (10) hydraulique d'alimentation en liquide sous pression dudit moteur (7) hydraulique; une vanne (11) hydraulique à ouverture rapide commandée agencée sur le circuit (10) hydraulique; un stockeur (9) pyro-hydraulique piloté par une unité (12) de commande et relié à ladite vanne (11) hydraulique, ledit stockeur (9) pyro-hydraulique comprenant : une enceinte (20) comprenant un piston (16) délimitant un compartiment (17) principal comprenant au moins une cartouche (19) de propergol solide, et un compartiment (18) de réserve de liquide; une charge (25) d'allumage reliée audit compartiment (17) principal et adaptée pour initier la combustion d'au moins une cartouche (19) de propergol solide sur commande de ladite unité (12) de commande.
