    • A bucket assembly cooling apparatus is provided. The bucket assembly includes a platform, an airfoil, and a shank. The airfoil may extend radially outward from the platform. The shank may extend radially inward from the platform. The shank may include a pressure side sidewall, a suction side sidewall, an upstream sidewall, and a downstream sidewall. The sidewalls may at least partially define a cooling circuit. The cooling circuit may be configured to receive a cooling medium and provide the cooling medium to the airfoil. The upstream sidewall may at least partially define an interior cooling passage and at least partially define an exterior ingestion zone. The cooling passage may be configured to provide a portion of the cooling medium from the cooling circuit to the ingestion zone of an adjacent bucket assembly.
    • 提供一种铲斗总成冷却装置。 铲斗组件包括平台,翼型件和柄。 翼型件可以从平台径向向外延伸。 柄可以从平台径向向内延伸。 柄部可以包括压力侧壁,吸力侧壁,上游侧壁和下游侧壁。 侧壁可以至少部分地限定冷却回路。 冷却回路可以被配置为接收冷却介质并将冷却介质提供给翼型件。 上游侧壁可以至少部分地限定内部冷却通道并且至少部分限定外部摄取区域。 冷却通道可以构造成将冷却介质的一部分从冷却回路提供给相邻铲斗组件的摄入区。

    • A measurement device, such as a laser radar, is described that comprises a transmitter portion for transmitting radiation to a remote probe volume, a receiver portion for detecting radiation returned from the remote probe volume and a processor for analysing the detected return radiation. The device is suitable for transmitting and receiving radiation through a window portion having associated window cleaning apparatus (e.g. wiper 62) for cleaning said window portion in response to a cleaning activation signal. The processor is arranged to generate a cleaning activation signal for activating window cleaning apparatus when the properties of said detected return radiation are indicative of a reduction in transmission through at least part of said window portion. In one embodiment, a conically scanned lidar is described that generates a cleaning activation signal when the power of detected return radiation varies as a function of the angle of transmission of radiation from the device.
    • 描述了诸如激光雷达的测量装置,其包括用于将辐射传输到远程探针体积的发射器部分,用于检测从远程探针体积返回的辐射的接收器部分和用于分析检测到的返回辐射的处理器。 该装置适于通过具有相关联的窗户清洁装置(例如擦拭器62)的窗口部分来发射和接收辐射,用于响应于清洁激活信号来清洁所述窗口部分。 当所述检测到的返回辐射的特性表示通过所述窗口部分的至少一部分的透射率减小时,处理器被布置成产生用于启动窗户清洁设备的清洁激活信号。 在一个实施例中,描述了锥形扫描的激光雷达,当检测到的返回辐射的功率随着来自设备的辐射的透射角度而变化时,产生清洁激活信号。
