Abstract: A system includes a vehicle control module, an operating information module, and a fuel analysis module. The vehicle control module is configured to obtain a trip plan for the vehicle. The operating information module is configured to be disposed on-board the vehicle and to autonomously obtain operating information describing one or more of tractive events or braking events performed during the trip. The fuel analysis module is configured to be disposed on-board the vehicle, to receive the operating information from the operating information module, and to autonomously determine a fuel consumption for at least a portion of the trip using the operating information received from the operating information module.

Abstract: The attachment of the blade to the disk of a gas turbine engine includes a sloped deep slot formed in the rim of the disk for accepting the dovetail of the root of he fan or compressor blade allowing the removal of a single blade from the disk and includes a segmented retainer plate disposed at the aft end of the bearing against the blade root to react out the slope induced axial blade loads providing a low hub-tip ratio configuration. A blade support disposed between the live rim of the disk and the bottom of the blade serves to support the blades radially during non-operating conditions and includes pockets for retaining weights for dynamic balance of the rotor. A forward mounted snap ring prevents forward movement of the blade during non-operating conditions.
