FIELD: internal combustion engines.
SUBSTANCE: invention relates to a turboshaft engine designed to equip a multi-engine, in particular a twin-engine, helicopter. Invention also relates to a twin-engine helicopter comprising at least one turboshaft engine, and to a method for optimising the zero-power super-idle speed of such a helicopter. Turboshaft engine comprises gas generator (5), designed to be rotated and free turbine (6) rotated by the gases from gas generator (5). Turboshaft engine also comprises device (40) for controlled mechanical coupling of gas generator (5) and said free turbine (6), said device being designed to connect gas generator (5) and said free turbine (6) mechanically, on command, once the rotation speed of gas generator (5) reaches a pre-determined threshold speed.
EFFECT: invention allows to reduce the temperature of the hot parts of the turboshaft engine, and to reduce fuel consumption.
