Title: AIRCRAFT PROPULSION UNIT, CONNECTED TO THE FUSELAGE OF SAID AIRCRAFT
Abstract:
The invention concerns an aircraft propulsion unit (1), comprising: - a turbojet engine (3); - a lateral pylon (7), connected to the fuselage of said aircraft, - a nacelle (5) mounted on said lateral pylon (7), comprising: - an upstream section (9), comprising an air intake (11) of the nacelle; - a downstream section (15), housing a reverse thrust device; - a middle section (13), comprising two fan half-cowls (13a, 13b), surrounding a fan housing of the turbojet engine and provided, when said half-cowls are in a closed position, in order to define an aerodynamic continuity between the upstream and downstream sections, the fan half-cowls comprising at least one maintenance half-cowl (13b) positioned under the horizontal median plane (53) of the nacelle, able to move between said closed position and an open position allowing access to the turbojet engine for maintenance operations on the turbojet engine. The propulsion unit is characterised in that the nacelle comprises at least one holding bolt (47), designed to hold said maintenance half-cowl (13b) in a position intermediate to the closed and open positions.
