US Patent:

6971241, Dec 6, 2005
Filed:

Nov 10, 2003
Appl. No.:

10/705580
Inventors:

Ian L. Critchley - Phoenix AZ, US
Barry J. Kingery - Glendale AZ, US
Cristopher Frost - Scottsdale AZ, US
David G. Walhood - Scottsdale AZ, US
Robert B. Sumegi - Phoenix AZ, US
Assignee:

Honeywell International Inc. - Morristown NJ
International Classification:

F02C007/268
US Classification:

60776, 60787, 60785
Abstract:

A gas turbine engine integrates the functions of an auxiliary power unit (APU) with one or more functions of an ECS, and that is capable of operating in both an unfired mode and a fired mode. The gas turbine engine includes a combustor system that is configured to allow the gas turbine to quickly transition from the unfired mode to the fired mode, by bypassing a portion of the air flowing to the combustor system around the combustor.

US Patent:

42742544, Jun 23, 1981
Filed:

Dec 22, 1977
Appl. No.:

5/863570
Inventors:

Harvey B. Jansen - Tempe AZ
Milton R. Adams - Tempe AZ
Robert B. Sumegi - Phoenix AZ
Klaus K. G. Huber - Xenia OH
John A. Salisbury - late of Phoenix AZ
Assignee:

The Garrett Corporation - Los Angeles CA
International Classification:

F02C 310
F02C 904
US Classification:

60 3903
Abstract:

A recuperated gas turbine engine fuel control valve and method which controls fuel flow during engine acceleration as a preselected empirical function of combustor gauge pressure and combustor inlet temperature, and which can also control fuel flow during deceleration without interruption of the combustion process.

42664012, May 12, 1981
Filed:

Dec 22, 1977
Appl. No.:

5/863205
Inventors:

Robert B. Sumegi - Phoenix AZ
Geoffrey D. Woodhouse - Phoenix AZ
George B. Mattson - Scottsdale AZ
Harvey B. Jansen - Tempe AZ
Frederic E. Bolliger - Phoenix AZ
Robert A. Hatch - Boca Raton FL
Assignee:

On/Off Surge Prevention Control For A Variable Geometry Diffuser

US Patent:

52358011, Aug 17, 1993
Filed:

Dec 12, 1991
Appl. No.:

7/805661
Inventors:

Kenneth W. Evenson - Scottsdale AZ
Daniel J. Kuhn - Phoenix AZ
Thomas Nesdill - Scottsdale AZ
Robert B. Sumegi - Phoenix AZ
Assignee:

Allied-Signal Inc. - Morris Township, Morris County NJ
International Classification:

F02C 900
F02G 300
US Classification:

60 3902
Abstract:

An on/off surge prevention control and method for a gas turbine engine having a variable geometry diffuser is provided. This control receives exhaust gas temperature and compressor discharge pressure signals from the engine, and a signal from the aircraft indicative of a need for bleed air. When the aircraft signal is received, the control opens the diffuser to its maximum open setting, and when said aircraft signal is absent closes said diffuser to its minimum open setting. In the event that a faulty aircraft signal is received, the control senses changes in EGT, P3 and dP3/dt and compares these parameters to preselected values indicative of the compressor nearing surge. When the measured values reach the preselected values, the control closes the diffuser to it minimum open setting. By using a temperature signal in determining when to close the diffuser, unwanted closings due to operating transients in compressor discharge pressure are provided. The control prevents the diffuser from being opened, until a second preselected EGT is reached.

US Patent:

52223566, Jun 29, 1993
Filed:

Dec 12, 1991
Appl. No.:

7/806565
Inventors:

Kenneth W. Evenson - Scottsdale AZ
Daniel J. Kuhn - Phoenix AZ
Thomas Nesdill - Scottsdale AZ
Robert B. Sumegi - Phoenix AZ
Assignee:

Allied-Signal Inc. - Morris Township, Morris County NJ
International Classification:

F02C 900
F02G 300
US Classification:

60 3902
Abstract:

A modulating surge prevention control and method for a gas turbine engine having a variable geometry diffuser is provided. The control calculates a maximum permissible compressor discharge pressure from a predetermined algorithim that is representative of the compressor discharge pressure when the compressor is operating at its minimum permissible surge margin with the diffuser in its maximum open position. The control also receives a signal from a sensor measuring the actual compressor discharge pressure. A error signal is formed by taking the difference between the measured pressure signal and the calculated signal. The control then continously adjusts the area of the diffuser so as to maintain the actual compressor discharge pressure at or below the calculated pressure. The calculated pressure is also corrected for variations in ambient temperature and altitude.
