    • A combustion engine (10) comprises a radial compressor (16) in flow communication via a flow passage (22) with a compressor-combustor array (20) radially outward of the radial compressor (16), both rotatable around a central axis (12). The compressor-combustor (20) comprises an array of rotor blades (26). The walls of the blades (26) define a plurality of chambers (28, 30). Each chamber (28, 30) has a flow inlet (32) to receive fluid from the radial compressor (16), and a flow outlet to exhaust fluid radially outwards from the compressor- combustor (20). The plurality of chambers (28, 30) comprises a first pilot combustion chamber (28a) and a second pilot combustion chamber (28b). The first pilot combustion chamber (28a) is provided with a first fuel injector (40a), and the second pilot combustion chamber (28b) is provided with a second fuel injector (40a). The first fuel injector (40a) is in flow communication with a first fuel reservoir (70a), and the second fuel injector (40b) is in flow communication with a second fuel reservoir (70b). The first fuel reservoir (70a) and the second fuel reservoir (70b) are each in fluid communication with a flow regulator (100), the flow regulator (100, 200, 300) operable to vary fuel flow delivery rate to the first reservoir (70a) and vary fuel flow delivery rate to the second reservoir (70b). The differential regulation of fuel flow between pilot combustion chambers results in different levels of thrust being generated downstream of the combustion chambers. In this way the engine is operable to produce vectored thrust.

    •  使用回転数範囲において,ロータの発電機側軸端とガスタービン軸端をバランス修正できる,ガスタービン構造とした。これによりロータをケーシングに組み込んだ後に,使用回転数の高回転数まで回転させながら,バランス修正することができ,ロータの弾性変形による不釣合いが発生する高回転数の残留アンバランスを除去し,不釣合い振動を低減することができる。 ガスタービンを組み立てる際に,同一回転軸上に構成されるガスタービン,圧縮機,発電機の組立に起因する残留アンバランスを低減することができ,危険速度における振動を増加させないガスタービンを提供することができる。
    • 一种校正形成的燃气轮机的平衡的方法,使得可以在使用转速的范围内校正转子的发电机侧轴端与燃气轮机的轴端之间的平衡。 在该方法中,在将转子组装在壳体中之后,在将转子旋转到高使用转速的同时,平衡被校正,以在由于弹性变形引起的不平衡的高转速下移除其残余不平衡 发生转子,以减少由于不平衡引起的振动。 因此,当组装燃气轮机时,可以减少由形成在同一旋转轴上的燃气轮机,压缩机和发电机组装而产生的残留不平衡。 结果,可以提供不会在临界转速下增加振动的燃气轮机。

    • A turbocompressor assembly (10) includes a first rotor stage (50) mounted on rotary shaft (51) and including circular rows of impeller blades (59-1, 59-2, 59-3) on one surface thereof separated by radial gaps in which opposed blade rows (29-1, 29-2) on a second rotor stage (20) are received. The two rotor stages are geared for counter-rotation and at least one of the rotors is perforated proximate its center (25) to allow air to be drawn between the opposed surfaces thereof, where its passage over the impeller blades develops useful torque. The opposed rotor surfaces are convolved to define a radially decreasing separation to an annular combustion cavity (73), and thereafter increasing with radius. Thus a radial compressor and a turbine function are developed by the respective blade rows on either side of the combustion cavity. The combustion cavity (73) may be formed in one of the rotors, or may be shared between the rotors as a communicating common annular chamber. Fuel may be delivered to the combustion chamber directly admixed into the air stream, or by a fuel delivery system (71).
    • 涡轮压缩机组件(10)包括安装在旋转轴(51)上的第一转子级(50),并且包括圆形排的叶轮叶片(59-1,59-2,59-3),其一个表面上由径向间隙 在第二转子平台(20)上相对的叶片排(29-1,29-2)被接纳。 两个转子级用于反向旋转,并且至少一个转子靠近其中心(25)穿孔,以允许空气在其相对的表面之间被拉伸,其中通过叶轮叶片的通道产生有用的转矩。 相对的转子表面被卷绕以限定到环形燃烧腔(73)的径向减小的间隔,然后以半径增加。 因此,径向压缩机和涡轮机功能由在燃烧腔的任一侧上的各个叶片排开发。 燃烧腔(73)可以形成在一个转子中,或者可以作为连通的公共环形室共享在转子之间。 燃料可以被输送到直接混合到空气流中的燃烧室,或者由燃料输送系统(71)输送。
