摘要
Turboshaft engines, twin engine helicopters having such turboshaft engines, and methods for optimizing unpowered super idle speeds of such twin engine helicopters The present invention relates to a turboshaft engine having a gas generator (5) which can be rotated and a free turbine (6) rotated by the gas of the gas generator (5), the rotational speed of the free turbine (NTL) As soon as the ratio of the rotational speed (NGG) of the gas generator to the 5) and a device (20) for spontaneously and mechanically coupling the free turbine (6).
