Patent number: 9926080Abstract: A system, which includes a plurality of heat exchangers and a compressing device, is configured to prepare in parallel a medium bled from a low-pressure location of an engine and flowing through a plurality of heat exchangers into a chamber. The compressing device is in communication with the plurality of heat exchangers and regulates a pressure of the medium flowing through the plurality of heat exchangers. The compressing device is bypassed based on the preparing in parallel the medium for the chamber, which in turn enables the compressing device to windmill. Therefore, the system employs at least one mechanism to prevent components of the compressing device from windmilling.Type: GrantFiled: February 11, 2015Date of Patent: March 27, 2018Assignee: HAMILTON SUNDSTRAND CORPORATIONInventors: Louis J. Bruno, Thomas M. Zywiak, Harold W. Hipsky, Christina W. Millot, Donald E. Army, Jr., Paul M. D'Orlando, Erin G. Kline

Patent number: 9856755Abstract: A power plant system including a fossil fuel fired power plant (6) for the generation of electricity, a carbon dioxide capture and compression system (5, 13), and an external heat cycle system has at least one heat exchanger (1,2,3) for the heating of the flow medium of the external heat cycle system. The heat exchanger (1,2,3) is connected to a heat flow from the CO2 capture plant (5) or a CO2 compression unit (13). A return flow from the heat exchanger (1,2,3) is led to the CO2 capture and compression system (5,13) or to the power plant (6). The power plant system allows an increase in overall efficiency of the system.Type: GrantFiled: April 25, 2011Date of Patent: January 2, 2018Assignee: General Electric Technology GmbHInventors: Paul Drouvot, Hongtao Li, Jörg Dietzmann

Patent number: 9718553Abstract: A cooling system for an aircraft includes a first cooling circuit having a first evaporator and a second evaporator, and a second cooling circuit having a third evaporator and a fourth evaporator. One of the first and second cooling circuits includes a first set of valves arranged to direct refrigerant through a first cooling sub-circuit, a second cooling sub-circuit, or both the first and second cooling sub-circuits based on ambient conditions. Two of the evaporators are installed on a first side of the aircraft, and the other two of the four evaporators are installed on a second side of the aircraft opposite the first side, and the first and second cooling circuits reject heat, via a heat exchanger, from their respective cooling circuit to air passing into an engine of the aircraft.Type: GrantFiled: December 27, 2013Date of Patent: August 1, 2017Assignee: Rolls-Royce North America Technologies, Inc.Inventors: Igor Vaisman, Douglas J.

Patent number: 9359949Abstract: A distributed bleed system temperature management scheme utilizes a distributed, closed loop temperature protection function. By allowing consumer systems to limit the consumer flow to meet a specified bleed system outlet temperature (which may be different for each consumer or group of consumers), each system can be penalized according to their level of importance. The closed loop approach allows optimization of the performance reduction instead of relying on conservative assumptions as is done with conventional systems. In some embodiments, each consumer system may have a different temperature limit at which the consumed flow is limited to maintain a given bleed system exit temperature. The temperature setpoints may be separated by a minimum temperature, based on sensor and controls tolerances, to ensure that the flow limiting functions do not interact with each other.Type: GrantFiled: February 17, 2011Date of Patent: June 7, 2016Assignee: HONEYWELL INTERNATIONAL INC.Inventors: Jason Olivarez, Giorgio Isella

Patent number: 9272787Abstract: A valve control system includes a valve connected to regulate flow of a medium provided to an output and a sensor connected to monitor a feedback value associated with the medium. A controller modulates the valve based on a comparison of a reference value to the feedback value provided by the sensor. The controller detects saturation of the valve if the error between the monitored feedback value and reference value exceeds a threshold. In response to detected saturation, the controller reduces the reference value to a value less than the monitored feedback value.Type: GrantFiled: April 12, 2013Date of Patent: March 1, 2016Assignee: Hamilton Sundstrand CorporationInventors: Lyndsay Morgan Couture, Erin G.
