Abstract: A method for controlling a vehicle system includes controlling a vehicle system having powered units that propel the vehicle system. A trip plan directs at least one of the powered units to remain in a non-propulsion generating mode during the trip. The method further includes slowing and/or stopping the vehicle system in contravention to the first trip plan, activating the at least one of the powered units out of the non-propulsion generating mode into an active, propulsion-generating mode when the vehicle system accelerates after the at least one of slowing or stopping in contravention to the first trip plan, and switching the at least one of the powered units back to the non-propulsion generating mode after the vehicle system achieves a designated speed following accelerating after the at least one of the slowing or stopping of the vehicle system in contravention to the first trip plan.

Abstract: A control system includes an energy management system and an isolation control system. The energy management system generates a trip plan that designates operational settings of a vehicle system having powered units that generate tractive effort to propel the vehicle system. The energy management system determines a tractive effort capability of the vehicle system and a demanded tractive effort of a trip. The energy management system identifies a tractive effort difference between the tractive effort capability of the vehicle system and the demanded tractive effort of the trip and selects at least one of the powered units based on the tractive effort difference. The isolation module remotely turns the selected powered unit to an OFF mode such that the vehicle system is propelled along the route during the trip by the powered units other than the selected powered unit.

Abstract: A control system for a rail vehicle system including a lead powered unit and a remote powered unit is provided. The system includes a user interface, a master isolation module and a slave controller. The user interface is disposed in the lead powered unit and is configured to receive an isolation command to turn on or off the remote powered unit. The master isolation module is configured to receive the isolation command from the user interface and to communicate an instruction based on the isolation command. The slave controller is configured to receive the instruction from the master isolation module. The slave controller causes the remote powered unit to supply tractive force to propel the rail vehicle system when the instruction directs the slave controller to turn on the remote powered unit. The slave controller causes the remote powered unit to withhold the tractive force when the instruction directs the slave controller to turn off the remote powered unit.

Abstract: An blade row for use in a compressor is provided. The blade row has a plurality of inlet guide vanes. Each inlet guide vane has a meanline approximately equal to NACA standard A4K6 meanline, a thickness distribution approximately equal to NACA standard SR 63 thickness distribution, a stagger angle, and a lift coefficient between 0.0 and 0.8.
