The invention relates to a turboshaft engine (10) in particular for a helicopter, that comprises a gas generator (12) and a free turbine (14) rotatingly driven by the gas flow (F) generated by the gas generator (12). The turboshaft engine (10) further includes a motor/generator coupled (30) to a shaft (18) of the gas generator (12) for providing an amount of additional rotational kinetic energy to the shaft (18) during an acceleration phase of the turboshaft engine (10) or for diverting an amount of rotational kinetic energy from the shaft (18) during a deceleration phase of the turboshaft engine.
On présente un turbomoteur (10) notamment pour un hélicoptère comportant un générateur de gaz (12) et une turbine libre (14) entrainée en rotation par le flux de gaz (F) généré par le générateur de gaz (12). Le turbomoteur (10) comporte en outre un moteur /générateur couplé (30) à un arbre (18) du générateur de gaz (12), pour fournir une quantité d'énergie cinétique de rotation supplémentaire à l'arbre (18) lors d'une phase d'accélération du turbomoteur (10), où de prélever une quantité d'énergie cinétique de rotation à l'arbre (18) lors d'une phase de décélération du turbomoteur.
