摘要： A propulsion system includes a bypass turbine engine and a pylon. The turbine engine includes an engine, two internal cowls, two outer cowls, a first lock for locking the internal cowls to the engine, cascades of vanes fixed to the outer cowl via hooping, wherein the outer cowls are movable in translation with respect to the engine, in which each outer cowl is able to slide parallel to a direction of translation on an internal cowl via a top guideway connection and a bottom guideway connection, and in which each outer cowl is mounted with the ability to slide parallel to the direction of translation on the pylon via an upper guideway connection. The propulsion system makes it possible during maintenance operations to move the outer cowl and the internal fixed structure towards the rear and therefore away from the front cowls to get at the engine.
