Patent number: 8365530Abstract: A system for conditioning an airstream entering an air-breathing machine includes an air conditioning system (ACS) configured for adjusting a physical property of the airstream, wherein the ACS comprises a module. The module includes a non-media conditioning system configured for adjusting a physical property of the airstream if an ambient condition is within a range, wherein the non-media conditioning system comprises nozzles adapted for spraying a fluid onto the airstream. The module also includes a media conditioning system configured for adjusting a physical property of the airstream to provide additional output of the air-breathing machine, wherein the media conditioning system comprises a direct exchange medium and a fluid distribution manifold. The ACS operates in a direct evaporative mode if the fluid is approximately greater than a dew point temperature and operates in a direct chilling mode if the fluid is approximately less than a dew point temperature.Type: GrantFiled: June 3, 2009Date of Patent: February 5, 2013Assignee: General Electric CompanyInventors: Jianmin Zhang, Douglas S.

Publication number: 20110146288Abstract: An embodiment of the invention applies a physics based approach to determine the mass flowrate of the fuel required for a robust ignition mode. This approach uses a closed-loop controls methodology. Here, a turbine control system receives a plurality of operating data. The turbine control system utilizes at least one algorithm, which applies an energy balance to the received operating data. The operating data may include, but is not limited to, airflow data, data from the fuel system, data related to the shaft work, exhaust data, and data related to the heat loss. This energy balance is used to determine the required mass flow rate.Type: ApplicationFiled: December 23, 2009Publication date: June 23, 2011Inventors: Douglas S. Byrd, Joseph R. Law
