Abstract
A turboshaft engine includes a casing in which is arranged a gas generator and a free turbine fitted to a power shaft. The power shaft is configured to be mechanically connected to/disconnected from a reduction gearbox. The turboshaft engine includes at least one centralizer movable between an active position, in which the centralizer forms a bearing for the power shaft and which corresponds to a mechanical disconnection between the power shaft and the reduction gearbox, and a passive position, in which the centralizer is distanced from the power shaft and which corresponds to a mechanical connection between the power shaft the reduction gearbox.
