A propulsion system (1) for helicopters, comprising a turboshaft engine (2) with a linked turbine and an electric machine (3) operable as an electric motor, said turboshaft engine (2) and said electric machine (3) being able to drive in rotation at least one main rotor (5) intended to be coupled to a rotary wing (6), characterized in that the main rotor (5) is driven by a motor (6). The invention relates to a propulsion system (1) comprising means (14) for coupling and decoupling, in rotation, between a rotor (3a) of said electric machine (3) and a rotor (2a) of said turboshaft engine (2), said coupling and decoupling means (14) being able to allow said rotor (2a) of said turboshaft engine (2) to be driven in rotation by means of said electric machine (3) in a first state of said propulsion system (1), the rotor (2a) of the turboshaft engine (2) and the rotor (3a) of the electric machine (3) are allowed to be decoupled in rotation in a second state of the propulsion system (1).

    一种用于直升机的推进系统(1),其包括具有联动涡轮的涡轮轴发动机(2)和能够作为电动马达操作的电机(3),所述涡轮轴发动机(2)和所述电机(3)能够在旋转中驱动既定联接到旋转机翼(6)的至少一个主旋翼(5),其特征在于,其包括用于在旋转中在所述电机(3)的旋翼(3a)和所述涡轮轴发动机(2)的旋翼(2a)之间联接和断开联接的构件(14),所述联接和断开联接的构件(14)能够允许所述涡轮轴发动机(2)的所述旋翼(2a)在所述推进系统(1)的第一状态中借助于所述电机(3)在旋转中被驱动,且能够允许所述涡轮轴发动机(2)的所述旋翼(2a)和所述电机(3)的所述旋翼(3a)在所述推进系统(1)的第二状态中在旋转中被解除联接。
