摘要:
A hybrid power plant (5) for an aircraft (1) comprises at least: a hybrid drive system (37) having a main on-board electricity network (16) and an auxiliary electricity network (34); and a selective adaptation interface (38) arranged to enable electrical energy to be exchanged selectively between the main and auxiliary electricity networks (16; 34). At least one engine and a hybrid drive auxiliary electrical machine (7, 31) are mechanically connected to a transmission (8); said machine (7) being electrically connected to at least one auxiliary electrical bus (36) in parallel with at least one auxiliary device for delivering electric charge.

摘要:
The invention provides a device and a method for starting at least one turbine engine (1) fitted to a helicopter. A starter (6) is fed with electrical energy from an electricity network (8) including at least one battery (9) and/or an electrical energy generator member. Discharge members (10) suitable for providing the starter (6) with a short-term boost of electrical energy in the form of a high-power pulse are incorporated in the network (8). The current pulse is delivered at a determined instant T starting from when the starter (6) is itself started, and/or from a determined threshold S for the speed and/or the variation in the speed with which the compressor (2) of the turbine engine (1) is driven, and/or from detecting D the ignition stage of the turbine engine (1), and/or from a manual control.
