Summary: | The invention relates to a device for rapidly reactivating a helicopter turbine engine (6). Said device is characterized in that it includes an air turbine (7) mechanically connected to said turbine engine (6) so as to be able to rotate it and ensure the reactivation thereof; - a pneumatic storage device (9) connected to said air turbine (7) by means of a pneumatic circuit (10) for supplying pressurized gas to said air turbine (7); and - a controlled, rapid-opening air valve (11) arranged on the pneumatic circuit (10) between said storage device (9) and said air turbine (7) and controllable at least in an open position, wherein the gas can be supplied to said air turbine (7), or in a closed position, wherein said air turbine (7) is no longer supplied with pressurized gas.
L'invention concerne un dispositif de réactivation rapide d'un turbomoteur (6) d'un hélicoptère, caractérisé en ce qu'il comprend une turbine (7) pneumatique reliée mécaniquement audit turbomoteur (6) de manière à pouvoir l'entraîner en rotation et assurer sa réactivation; un stockeur (9) pneumatique relié à ladite turbine (7) pneumatique par le biais d'un circuit (10) pneumatique d'alimentation en gaz sous pression de ladite turbine (7) pneumatique; une vanne (11) pneumatique à ouverture rapide commandée agencée sur le circuit (10) pneumatique entre ledit stockeur (9) et ladite turbine (7) pneumatique et adaptée pour être placée sur commande au moins dans une position ouverte dans laquelle le gaz peut alimenter ladite turbine (7) pneumatique, ou dans une position fermée dans laquelle ladite turbine (7) pneumatique n'est plus alimentée en gaz sous pression. |
