    Abstract: A gas turbine has a stationary turbine rotor shroud of ceramic mounted on a metal ring. The mounting is resilient metal pins received in circular holes in the shroud ring and in radially extending slots in the supporting ring to allow relative radial expansion while centering the shroud ring with the turbine axis. The locating pins are slightly barrel-shaped and are slotted through the intermediate portion of the pins so they fit snugly in the ceramic but are yieldable to accommodate slight relative shifting or differential thermal expansion of the pin and shroud without imposing high local stresses on the ceramic material.

    Abstract: A power train having a gas turbine engine with a controlled power transfer clutch between the compressor turbine and the load turbine driving a power shift transmission. The engine control system includes a fuel control and a power and torque program control responsive to compressor and auxiliary torque and speed controlling the power transfer clutch to provide engine output power and maintain constant high turbine inlet temperature in a wide range of operation for optimum efficiency. The power shift transmission control has shift control valving to selectively supply control pressure to the fluid operated drive motors to selectively establish neutral and a plurality of drives. A flow valve responsive to flow filling a motor for establishing a drive controls a power transfer clutch cut off valve to disconnect the power transfer clutch providing normal engine idle during establishment of a drive. Energizing the starter circuit requires first manually placing the transmission control in neutral and then discontinues fluid feed to the engine and transmission controls, unloads the engine and transmission pumps, disengages the power transfer clutch, provides a low idle throttle stop and further ensures positive neutral in the transmission. When the engine is started and the transmission control is in neutral, the engine power clutch is disengaged, the throttle stop is in low idle, the transmission is in positive neutral and only lubrication pressure is supplied to the transmission.

    Abstract translation: 具有在压缩机涡轮机和负载涡轮机之间具有受控的动力传递离合器的燃气涡轮发动机的动力传动系统驱动动力换挡变速器。 发动机控制系统包括燃料控制和响应于压缩机和辅助转矩的功率和扭矩程序控制，并且控制动力传递离合器的速度以提供发动机输出功率并且在宽范围的操作中保持恒定的高涡轮机入口温度以获得最佳效率。 动力换档变速器控制具有换档控制阀，以选择性地向流体驱动的驱动马达提供控制压力，以选择性地建立空档和多个驱动器。 响应于流动的流量阀，用于建立驱动器以控制动力传递离合器切断阀，以断开在驱动器建立期间提供正常发动机空转的动力传递离合器。 启动起动器电路需要首先手动将变速器控制置于空档状态，然后停止对发动机和变速器控制器的流体进给，卸载发动机和变速器泵，使动力传递离合器脱离，提供低怠速节气门停止，并进一步确保正向中性 传输。 当发动机起动并且变速器控制处于中立状态时，发动机动力离合器分离，节气门止动器处于低怠速状态，变速器处于正中性，并且仅向变速器供给润滑压力。
