摘要： The invention relates to a nacelle for a variable area nozzle propulsion unit comprising a nacelle, hosting a turbofan jet engine, of dual-flow type. The propulsion unit includes: a fixed part, carried by the inboard half-nacelle defined by a vertical plane of symmetry of the nacelle; and a movable part carried by the outboard half-nacelle. The moving part containing or releasing part of the secondary flow, depending on its open or closed position. The moving part being able to move to a discrete number of positions including a closed position, an open position, and one or more intermediate positions so as to provide variable area nozzle configurations for the turbofan engine.

摘要： A power plant includes a nacelle with a bypass turbojet engine having a ducted fan with a low compression ratio. A secondary flow, drawn in and accelerated by the fan, is channeled through a secondary duct installed in the nacelle between the inner surface of the nacelle and the outer surface of the turbojet, toward a fan nozzle. The power plant has at least two moving parts on either side of a vertical plane of symmetry of the nacelle, at least one moving part being able to adopt one of a discrete number of positions, the moving part containing or releasing a portion of the secondary flow, depending on the moving part's position. A control unit controls a different displacement of each of the moving parts between their possible positions in order to create asymmetry of the moving parts relative to the vertical plane of symmetry.
