DEVICE AND A METHOD FOR STARTING A TURBINE ENGINE FITTED TO A HELICOPTER, MAKING USE OF AN ELECTRICAL ENERGY SOURCE THAT INCLUDES DISCHARGE BOOSTER MEMBERS
First Claim
1. A device for starting at least one turbine engine fitted to a helicopter, the device comprising a starter that is powered with electrical energy from an electricity network including at least one source of electrical energy including at least one battery and/or an electrical energy generator member;
- the source of electrical energy further including discharge members suitable for providing the starter with a short-term electrical energy boost in the form of a high-power pulse;
a plurality of the discharge members being grouped together in at least one module;
wherein the discharge members of a module are grouped together by the dozen, have individual capacitance of the order of 3000 F, and a unit voltage of about 2.7 Vdc, and are connected in series so as to make the module suitable for use on a network having a voltage of about 28 Vdc;
at least some of the discharge members forming an accessory for mounting in removable manner in the network on board the helicopter.

Abstract
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.
