摘要： The present invention relates to a bypass turbojet engine nacelle (10) that forms the fan casing comprising a first, upstream, streamlining element (12) and a second streamlining element (13) that forms the jet pipe, the second element having the ability to move translationally between a position in which it ensures the aerodynamic continuity of the nacelle and a downstream position uncovering flow reversal openings, a thrust reverser device being housed in the nacelle and comprising flow reverser flaps (17) and cascades of vanes (15) providing radial guidance for the flow. The nacelle is characterized in that the cascades of vanes (15) providing radial guidance for the flow are capable of translational movement along the axis of the nacelle between a position in which they are retracted into the first steamlining element (12) and an active flow-guidance position, the second fan streamlining element (13) being secured to said guide cascades of vanes (15) the reverser flaps (17) being mounted with the ability to rotate about axes that are transverse with respect to the axis of the nacelle and secured to the cascades of vanes (15).
