| 摘要 |
The invention relates to a turboshaft engine comprising a gas generator (5) designed to be rotated and a free turbine (6) rotated by the gases from the gas generator. The turboshaft engine is characterised in that it comprises a device (40) for the controlled mechanical coupling of the gas generator (5) and the free turbine (6), said device being designed to connect the gas generator (5) and the free turbine (6) mechanically, on command, once the rotation speed of the gas generator (5) reaches a pre-determined threshold speed. |
