Abstract
A propulsion system () for a helicopter, comprising a turboshaft engine () with a linked turbine and an electric machine () capable of operating as an electric motor, the turboshaft engine () and the electric machine () being capable of driving in rotation at least one main rotor () intended to be coupled to a rotating wing () characterised in that it comprises means of coupling and decoupling () in rotation between a rotor () of the electric machine () and a rotor () of the turboshaft engine (), the means of coupling and decoupling () being capable of allowing the rotor () of the turboshaft engine () to be driven in rotation with the aid of the electric machine (), in a first state of the propulsion system (), and capable of allowing the rotor () of the turboshaft engine () and the rotor () of the electric machine () to be decoupled in rotation, in a second state of the propulsion system ().
