    • A gas turbine engine power unit (10) comprises a gas generator (11) having a valve (21) located at its downstream end. The valve (21) receives the exhaust efflux of the gas generator (11) and directs it either to a plurality of turbochargers (32) to boost the output power of the unit (10) or to a plurality of heat exchangers (39) to provide regeneration of the unit (10). The valve (21) comprises a rotary portion (20) which rotates within a static portion (28) to provide alignment of apertures within both portions (20,28) to facilitate the direction of the gas generator (11) exhaust efflux.
    • 燃气涡轮发动机动力单元(10)包括具有位于其下游端的阀(21)的气体发生器(11)。 阀(21)接收气体发生器(11)的排气流,并将其引导到多个涡轮增压器(32),以将单元(10)的输出功率或多个热交换器(39)的输出功率提升到 提供单元(10)的再生。 阀(21)包括旋转部分(20),旋转部分(20)在静止部分(28)内旋转以提供两个部分(20,28)内的孔的对准,以便于气体发生器(11)的排出方向。

    • A turbofan gas turbine engine comprising in axial flow series a fan, a booster compressor and a core engine is provided with a diffuser. The diffuser is positioned axially between the booster compressor and the compressor of the core engine to efficiently diffuse the air from the fan to the compressor of the core engine. The diffuser comprises a plurality of circumferentially arranged geodesic pipe diffusers, the pipe diffusers extend axially and radially and the outlets of the pipe diffusers are displaced circumferentially by an angle of between 20.degree. and 60.degree. with respect to the inlets of the pipe diffusers.The geodesic pipe diffusers allows the airflow between the fan and the core engine to be diffused adequately without compromising the efficiency of the core engine, or the high mass flow rate of the fan and also minimizes the length, weight and drag of the gas turbine engine.
    • 涡轮风扇燃气涡轮发动机具有散热器,该涡轮风扇燃气涡轮发动机具有轴流式系列,风扇,增压压缩机和核心发动机。 扩散器轴向位于增压压缩机和核心发动机的压缩机之间,以有效地将空气从风扇扩散到核心发动机的压缩机。 扩散器包括多个周向布置的测地管扩散器,管道扩散器沿轴向和径向延伸,并且管道扩散器的出口相对于管道扩散器的入口沿圆周方向偏移20°至60°的角度。 测地管扩散器允许风扇和核心发动机之间的气流充分扩散,而不会影响核心发动机的效率,或风扇的高质量流量,并且还使燃气涡轮发动机的长度,重量和阻力最小化 。
