1. A propulsion unit for an aircraft, comprising a nacelle, a support structure and first connecting means configured to connect a propelling turbomachine to the support structure, the nacelle comprising an air inlet and a gas ejection rear section, wherein the propulsion unit further comprises second connecting means connecting the air inlet and/or the rear section of the nacelle to the support structure so that the support structure supports the propelling turbomachine via the first connecting means and so that the support structure supports the air inlet and/or the rear section of the nacelle via the second connecting means, the second connecting means comprising a hinge member configured to enable a movement of a nacelle element, said nacelle element being one of the air inlet and the rear section, between:
a flight position, in which a central axis of said nacelle element and a longitudinal central axis of the propulsion unit are coincident with or parallel to each other, and
a maintenance position, in which the central axis of said nacelle element and the longitudinal central axis of the propulsion unit are oblique or perpendicular to each other.
