  • Patent number: 11062533
    Abstract: A sensing system is provided. The sensing system includes a processor, a sensor node, a plurality of sensors, a power source and a controller. The sensor node is operably connected to the processor on an industrial side and to the sensors on a sensor side. The sensors each measure a parameter of the sensing system and transmit the parameter to the processor via the sensor node. The power source delivers power to the processor. The controller is in operable communication with the processor. The sensor node, disposed in close proximity to the sensors, converts a data protocol for each of the sensors to a different industrial protocol and transmits the converted data through a communication port via the industrial data protocol to the processor. The processor then collects the measurements of each parameter of the plurality of sensors, analyses the measurements and transmits the analyzed data to the controller.

  • Patent number: 10830083
    Abstract: A gas turbine engine having a turbine blade tip clearance control system for increasing the efficiency of the engine by reducing the gap between turbine blade tips and radially outward ring segments is disclosed. The turbine blade tip clearance control system may include one or more clearance control bands positioned radially outward of inner surfaces of ring segments and bearing against at least one outer surface of the ring segments to limit radial movement of the ring segments. During operation, the clearance control band limits radial movement of the ring segments, and the turbine blade tips do not have a pinch point during start-up transient conditions. In addition, the smallest gap during turbine engine operation may be found at steady state operation of the gas turbine engine. Thus, the clearance control system can set the gap between turbine blade tips and ring segments to be zero at steady state operation.
