Title
(EN) Architecture of a multi-engine helicopter propulsion system and corresponding helicopter
(ZH) 多引擎直升机推进系统的架构以及对应的直升机
Abstract
(EN)
The invention relates to an architecture of a multi-engine helicopter propulsion system comprising turbine engines (1, 2) connected to a power transmission gearbox (3), and a low-voltage on-board DC network (7) intended to power helicopter equipment during flight, characterized in that the architecture comprises: a hybrid turbine engine (1) able to operate in at least one standby state during steady stabilized flight of the helicopter; an electrotechnical pack (20) for the rapid restart of said hybrid turbine engine in order to cause it to exit said standby state and attain a state in which it supplies mechanical power, said restart pack (20) being connected to said onboard network (7); and at least two sources (4, 16, 18) for electrically powering said on-board network (7).
