摘要： A convoy management system and method determine determining an inter-vehicle spacing in a convoy formed from two or more vehicles traveling together along one or more routes. Controllers onboard the two or more vehicles are instructed to automatically change movement of at least one of the vehicles in the convoy to maintain the inter-vehicle spacing. The inter vehicle spacing is dynamically changed during movement of the convoy along the one or more routes.

摘要： A system and method for determining dynamically changing distributions of vehicles in a vehicle system are disclosed. The system and method determine handling parameters of the vehicle system. The handling parameters are determined for different distributions of the vehicles among different groups at different potential change points along a route. The system and method also determine whether to change the distributions at potential change points based on the handling parameters. Based on determining that the distributions are to change, a selected sequence of changes to the distributions is determined at one or more of the potential change points along the route. Change indices are generated based on the selected sequence. The change indices designate times and/or the one or more potential change points at which the distributions changes. The vehicles included in a common group have common designated operational settings while the vehicles are in the common group.

摘要： An engine control system may be configured to perform a method of controlling thermal bias in a turbomachine. An exemplary method may include determining a thermal bias-value for the turbomachine, and performing a cooling treatment based at least in part on the thermal bias-value. The thermal bias-value may include a difference between an upward temperature-value corresponding to a first one or more temperature measurements of an upward portion of the turbomachine and a downward temperature-value corresponding to a second one or more temperature measurements of a downward portion of the turbomachine. The cooling treatment may include at least one of: circulating air through at least a portion of the turbomachine, and rotating a shaft of the turbomachine with a motoring system.

摘要： A manufacturing computer device for dynamically adapting additive manufacturing of a part is provided. The manufacturing computer device includes at least one processor in communication with at least one memory device. The at least one memory device stores a build file for building the part including a plurality of geometries that each include one or more values of a first build parameter. The processor is programmed to receive sensor information of a build of the part by a machine, compare the sensor information for each geometry of the plurality of geometries to the corresponding one or more values of the first build parameter, determine one or more values for a second build parameter for each of the geometries based on the one or more differences, and generate an updated build file for the part including the one or more values for the second build parameter.

摘要： A component is fabricated in a powder bed by moving a laser array across the powder bed. The laser array includes a plurality of laser devices. The power output of each laser device of the plurality of laser devices is independently controlled. The laser array emits a plurality of energy beams from a plurality of selected laser devices of the plurality of laser devices to generate a melt pool in the powder bed. A non-uniform energy intensity profile is generated by the plurality of selected laser devices. The non-uniform energy intensity profile facilitates generating a melt pool that has a predetermined characteristic.

摘要： A power control system for a vehicle system identifies coupler nodes in the vehicle system for travel of the vehicle system along a route. The coupler nodes represent slack states of couplers between vehicles in the vehicle system. The system also determines combined driving parameters at locations along the route where a state of the coupler nodes in the vehicle system will change within the vehicle system during the upcoming movement of the vehicle system. The system determines a restriction on operations of the vehicle system to control the coupler nodes during the upcoming movement of the vehicle system and to distribute the combined driving parameters among two or more of the vehicles.

摘要： A system and method identifies vehicles to be included in a multi-vehicle system that is to travel along one or more routes for an upcoming trip, and determines plural different potential builds of the multi-vehicle system. The different potential builds represent different sequential orders of the vehicles in the multi-vehicle system. The system and method also simulate travels of the different potential builds for the upcoming trip, calculate a safety metric, consumption metric, and/or build metric for the different potential builds based on travels that are simulated, and generates a quantified evaluation of the safety metric, consumption metric, and/or build metric for the different potential builds for use in selecting a chosen potential build of the different potential builds. The chosen potential build is used to build the multi-vehicle system for the upcoming trip.

摘要： A gas turbine engine is provided having: a turbomachine; a fan section having a fan rotatable by the turbomachine; a nacelle enclosing the fan; and an engine controller positioned within the nacelle. The nacelle defines an inner surface radius (r) along the radial direction inward of the engine controller, wherein the engine controller defines a radial height (Δr) along the radial direction, a total volume (V), and a normalized radius (r′). The normalized radius (r′) is a ratio of the inner surface radius (r) to the total volume (V) to cube root, and wherein these parameters are related by the following equation:
