    摘要： A variable geometry convergent-divergent nozzle for a gas turbine engine includes a centerbody extending rearward along a longitudinal axis of the engine which has a maximum diameter section. An inner shroud surrounds the centerbody and cooperates with the centerbody to define the throat of the nozzle. An outer shroud surrounds the inner shroud and cooperates with the centerbody to define the exit area of the nozzle. Both shrouds are independently translatable to provide independent control of the nozzle throat area and the nozzle expansion ratio. Additional actuation of the inner shroud results in the throat A8 being disposed upon a fully forward portion of the centerbody, said fully forward shroud disposition being more forward than over the maximum diameter section. The nozzle may further comprise independent translation of the centerbody 32 with respect to the shrouds.

    摘要： A gas turbine engine includes a first airflow structure (23) and a second airflow structure (36) disposed aft of the first airflow structure (29). The second airflow structure (23) includes a leading edge region (72). A thickness of the leading edge region (72) is based on a thickness of a wake (64) in the airflow produced by the first airflow structure (23) when the airflow passes between the first airflow structure (23) and the second airflow structure (36).

    摘要： The invention relates to a thrust reverser for a turbojet engine nacelle, comprising a mobile cowl that can move in translation in a direction substantially parallel to a longitudinal axis of the nacelle, said mobile cowl being extended by at least one part forming a mobile variable nozzle associated with at least one driving means for driving same in translation in a substantially longitudinal direction of the nacelle. The thrust reverser is characterised in that the deflection means are mounted such that they can move between a retracted position and an active position in which they are moved downstream such that they can extend through a passage opened by the mobile cowl into the nacelle, and in that the deflection means are associated with at least one driving means that can be decoupled from the driving means of the variable nozzle.

    摘要： The invention relates to a nacelle (1) for a turbojet engine, including a stationary portion (5) and a thrust reversal means (15), including: - a reverser cowl, the downstream portion of which forms an exhaust nozzle; cascades; thrust reversal flaps; and an actuation means. The thrust reversal means (15) translates, by means of the actuation means, between a position in which the reverser cowl is stowed, corresponding to a direct-jet operation of the nacelle, and a position in which the reverser cowl is deployed, corresponding to a reverse-jet operation of the nacelle (1). The nacelle (1) is characterized in that stretching said actuation means has the sole effect of causing a variation in the cross-section of the nozzle as long as said stretching is less than a predetermined value, and of uncovering the cascades and deploying the flaps after said predetermined value is exceeded.
