Patent

CA 2719461

The invention relates to a turbine engine (10) particularly for a helicopter, which comprises a gas generator (12) and a free turbine (14) rotated by a gas flow (F) generated by the gas generator, wherein the turbine engine further includes a reversible electric machine (30) that can be coupled to the gas generator, said reversible electric machine being capable of rotating the gas generator (12) during the starting phase of the turbine engine. The invention is characterised in that the reversible electric machine (30) can also be coupled to the free turbine (12) after the starting phase of the turbine engine in order to generate electric power.

L'invention concerne un turbomoteur (10), notamment pour un hélicoptère, comportant un générateur de gaz (12) et une turbine libre(14) entraînée en rotation par un flux de gaz (F) généré par le générateur de gaz, le turbomoteur comprenant en outre une machine électrique réversible (30) apte à être couplée au générateur de gaz, ladite machine électrique réversible étant apte à mettre en rotation le générateur de gaz (12) lors d'une phase de démarrage du turbomoteur. L'invention se caractérise par le fait que la machine électrique réversible(30) est en outre apte à être couplée à la turbine libre (12) après la phase de démarrage du turbomoteur afin de générer de l'énergie électrique.
