An emergency supply unit is provided with a ram-air turbine surrounded substantially concentrically by a casing forming a flow channel and driven by an air stream; an energy converter, driven by means of the ram-air turbine directly coupled via a drive shaft, for at least partly maintaining the functioning of a hydraulic system and/or electrical system on board an aircraft in an emergency situation; means for installing the ram-air turbine in its position within the casing such that the spatial position of the ram-air turbine remains unchanged when the emergency supply unit is selectively brought into a standby mode or into an operating mode; at least one air inlet through which the air stream can be delivered to the ram-air turbine, and which is adapted to be closed by a shut-off member; and an air outlet adapted to be closed by a shut-off member.
