ARCHITECTURE OF A MULTIPLE-ENGINE HELICOPTER PROPULSION SYSTEM, AND CORRESPONDING HELICOPTER |
摘要 |
The invention relates to an architecture of a multiple-engine helicopter propulsion system comprising turbine engines (1, 2) which are connected to a power transmission gearbox (3), comprising: a hybrid turbine engine (1) able to operate in at least one standby state during steady stabilized flight of the helicopter; a pack (5, 6) with a rapid restarting of said hybrid turbine engine (1) to cause it to exit said standby state and attain a nominal operating state; an auxiliary power unit (11) connected to said electrotechnical restart pack (5, 6) via a first (10) AC/DC converter designed, on demand, to supply said restart pack (5, 6) with the power required to cause said hybrid turbine engine (1) to leave said standby state. |
