Abstract: Systems and methods for database record synchronization are disclosed herein. An example apparatus includes at least one memory; machine readable instructions; and processor circuitry to execute the machine readable instructions to perform a comparison between a first record and a second record, the first record associated with a first database and the second record associated with a second database different than the first database, the first record including a base record and a supplemental record and the second record including a base record and a supplemental record; determine a sequence in which to modify the second record based on the comparison; and cause transmission of a first message and a second message to the second database based on the sequence to modify the second record.

Abstract: Systems and method for database record synchronization are disclosed herein. An example apparatus includes a request receiver to receive a request including a first record. The first record is stored in a first database. The example apparatus includes a database searcher to search a second database for a second record based on the request. The example apparatus includes a record parser to generate a first parsed record based on the first record and a second parsed record based on the second record, perform a comparison of the first parsed record and the second parsed record, and identify a difference between first data in the first parsed record and second data in the second parsed record. The example apparatus includes a communicator to transmit a transaction message to the second database to modify the second data based on the first data.

Abstract: The system and method of the present invention provides stepping speed control of a gas turbine engine to reliably light-off a gas turbine engine. During starting, the speed of the gas turbine engine is incremented by stepped amounts through the light-off window from a minimum speed value to a maximum speed value, with the speed of the gas turbine dwelling at each stepped value for a period of time before incrementing the speed of the engine to the next stepped level. If the gas turbine engine is stepped through the entire light-off window without success, the controller decreases the speed of the gas turbine engine to the minimum value and begins the process again. The process continues until successful light-off is initiated or until the light-off window is traversed a certain number of times, after which the start process is aborted.

Abstract: An active thrust management system varies pressure responsive to changes in rotor assembly thrust to maintain a desired position. The system includes a bearing supporting rotation of a rotor assembly within a pressurizing chamber. The rotor assembly is supported on a cushion of air generated between the bearing and the rotor assembly. Pressure within a cavity adjacent the rotor assembly opposes a thrust force to maintain a desired position of the rotor assembly. Modulating airflow into the pressurizing chamber adjacent the rotor assembly compensates for changes in the thrust generated by the rotor assembly to maintain the desired rotor assembly position.
