    • A pair of cold air driven tubines are mounted in-line with each turbine driving one of two coaxial drive shafts. Each drive shaft is independently supported and separate drive air is supplied to each turbine such that the direction and speed of rotation of each drive shaft is independently controlled. Exhaust air from the forward turbine vents through an exhaust cavity that surrounds the aft turbine. Inlet drive air to the aft turbine is supplied via air ducts formed through the center of struts which extend radially from the inlet of the aft turbine, through the exhaust cavity and to an inlet port external to the turbine housing.
    • 一对冷气驱动的锭子与驱动两个同轴驱动轴之一的每个涡轮机一起安装。 每个驱动轴被独立地支撑,并且向每个涡轮机供应单独的驱动空气,使得每个驱动轴的旋转方向和速度被独立地控制。 来自正向涡轮机的排气通过围绕后涡轮机的排气腔排气。 进入后涡轮机的入口驱动空气通过空气管道供应,该空气管道通过从后涡轮机的入口径向延伸的支柱中心形成,穿过排气腔并且到达涡轮壳体外部的入口。
