    • Fan jet engine has cowl surrounding engine and terminating in jet exhaust nozzle. Elongate shroud surrounds fan and engine to define annular passage for fan air and terminates forward of exit end of exhaust nozzle. Aft portion of shroud is separate sleeve movable axially rearward to define peripheral gap for inflow of free stream air to add to mass delivered by fan. Engine cowl converges rearwardly from transverse plane of aft end of sleeve. When sleeve is stowed it defines with the cowl a convergent nozzle of minimum discharge area. When it is fully deployed, it forms with the cowl a divergent nozzle of maximum discharge area conformed to produce optimum thrust for takeoff.

    • A system for reducing noise caused by a stream of fluid comprises a fluid ejection conduit comprising two series of ambient fluid intake vents distributed around its periphery; and Two series of orientatable tubular elements respectively connected to the said vents and arranged to occupy two positions, namely a retracted position in which they are folded back adjacent the inner wall of the conduit and form along the latter a substantially continuous ring bounding a continuous passage for the stream of fluid, and a noise-attenuating position in which the said tubular elements extend obliquely rearwardly and towards the axis of the conduit, the elements of the first series abutting one another at their free end in the noise-attenuating position so as to form a substantially continuous outlet ring for the ambient fluid, while the elements of the second series in the noise-attenuating position lead into the conduit at different distances from the axis of the latter as compared to the distances of the conduits of the other series in the noiseattenuating position.

    • A multi stream aircraft fixed geometry nozzle includes an inner nozzle, an outer nozzle, and a supersonic ejector. The outer nozzle is configured to channel a third stream from an aft end of a third stream duct surrounding a bypass duct of a multi stream aircraft engine to the supersonic ejector to merge the third stream with the primary stream. The fixed geometry nozzle is configured to operate between an SFC mode and a thrust mode such that, when the inner nozzle accelerates the primary stream supersonically to the supersonic ejector, at which the primary stream is merged with the third stream, in the SFC mode the total pressure of the primary stream is substantially the same as the total pressure of the third stream, and in the thrust mode the total pressure of the primary stream is substantially greater than the total pressure of the third stream.

    • An aircraft control structure can be utilized for purposes of drag management, noise control, or aircraft flight maneuvering. The control structure includes a high pressure engine nozzle, such as a bypass nozzle or a core nozzle of a turbofan engine. The nozzle exhausts a high pressure fluid stream, which can be swirled using a deployable swirl vane architecture. The control structure also includes a variable geometry pylon configured to be coupled between the nozzle and the aircraft. The variable geometry pylon has a moveable pylon section that can be deployed into a deflected state to maintain or alter a swirling fluid stream (when the swirl vane architecture is deployed) for drag management purposes, or to assist in the performance of aircraft flight maneuvers.

    • An adjustable bloom mixer for a turbofan engine for setting a mixing ratio, adapted to the respective flight condition, between cold airflow in the bypass duct and hot airflow in the core flow duct includes an air-guiding element (13) arranged upstream of a thin-walled, corrugated part (6b) of the bloom mixer (6) for branching off a cold partial airflow and/or a hot partial airflow from the bypass duct and from the core flow duct of the engine. An air control device (14) is assigned to the air-guiding element (13) for leading the branched-off cold airflow or hot airflow along the inner surface and/or the outer surface of the bloom mixer (6) in order to deflect its corrugated part (6b) radially inwards or outwards on the basis of a temperature difference between an inner and an outer surface effected by the hot and/or cold partial airflow.
