    • A gas turbine engine exhaust nozzle (28) includes coaxial inner and outer conduits (2,1). The inner conduit (2) has a main outlet (20) at an aft end thereof, and a row of radial apertures (4) spaced upstream from the outlet. The outer conduit (1) has an auxiliary outlet (10) at an aft end thereof, and surrounds the inner conduit (2) over the apertures (4) to form a bypass channel (36) terminating at the auxiliary outlet (10). A plurality of flaps (5) are hinged at upstream ends thereof to selectively cover and uncover corresponding ones of the apertures (4) and selectively bypass a portion of exhaust flow from the inner conduit (2) through the outer conduit (1) in confluent streams from both the main and auxiliary outlets (20,10).

    • PROBLEM TO BE SOLVED: To propose a small core exhaust mixer having a variable area capable of reducing a noise level of a jet engine in a takeoff.
      SOLUTION: This invention relates to the core exhaust mixer having the variable area for the turbofan jet engine of the supersonic aircraft. This has a nozzle 24 arranged around a gas generator of the jet engine. The nozzle has a plurality of external air intake apertures 30 existing in a convergence zone between a low temperature flow and a high temperature flow from the gas generator. Lobes 32 movable between two positions of a first position for closing an opening part 30 of the nozzle 24 and a second position different from the first position and extending radially in the nozzle 24 for taking in external air, are installed in these intake apertures. The lobes 32 have an azimuthal component in the same direction in order to give swirling motion to the external air admitted into the convergence zone when the lobes exist in the second position.

    • An exhaust nozzle (38) includes an outer duct (50) surrounding an inner duct (36). The inner duct (36) includes a main outlet (46), and a row of aperture (48) spaced upstream therefrom. The outer duct (50) includes a row of intake (52) at a forward end, an auxiliary outlet (54) at an aft end, and surrounds the inner duct (36) over the apertures to form a bypass channel (56) terminating at the auxiliary outlet (54). A row of flaps (58) are hinged at upstream ends to selectively cover and uncover the apertures (48) for selectively bypassing a portion of exhaust flow from the inner duct (36) through the outer duct (50) in confluent streams from both main and auxiliary outlets (46,54). When the flap (58) cover the apertures, the intake (52) ventilate the bypass channel (56) and discharge flow through the auxiliary outlet (54).
    • 排气喷嘴(38)包括围绕内部管道(36)的外部管道(50)。 内部管道(36)包括主出口(46)和与其上游间隔开的一排孔(48)。 外部管道(50)包括在前端处的一排入口(52),在后端处的辅助出口(54),并且围绕所述孔围绕内部管道(36),以形成终止的旁路通道(56) 在辅助出口(54)处。 一排襟翼(58)在上游端铰接以选择性地覆盖和露出孔(48),用于选择性地绕从内管道(36)通过外管道(50)排出的一部分排气流从两个主流 和辅助出口(46,54)。 当翼片(58)覆盖孔时,进气口(52)使旁通通道(56)通风,并通过辅助出口(54)排出流量。
