US Patent:

8146370, Apr 3, 2012
Filed:

May 21, 2008
Appl. No.:

12/124362
Inventors:

Peter Kenneth Zeiner - Scottsdale AZ, US
Tony Libera - Tempe AZ, US
Todd Langston - Chandler AZ, US
Assignee:

Honeywell International Inc. - Morristown NJ
International Classification:

F02C 3/10
F02C 6/00
US Classification:

60792, 60802, 60778, 60786
Abstract:

A pneumatically driven turbine drive system is coupled to a gas turbine engine that includes low and high pressure compressors, low and high pressure turbines, a lock-up clutch, and at least one engine accessory driven by the high pressure compressor. The pneumatically driven turbine drive system selectively bleeds air discharged from the high pressure compressor and supplies it to an air turbine that is coupled to the at least one engine accessory. Thus, the system selectively reduces the power extracted from the high pressure compressor and is capable of supplying power back to the engine core. This, coupled with the bleed air that is diverted from the high pressure turbine and the low pressure turbine, allows the high pressure spool and the low pressure spool to run at lower speeds when high engine thrust is not needed or desired, but when the at least one engine accessory is still needed.

US Patent:

8291715, Oct 23, 2012
Filed:

Jun 11, 2008
Appl. No.:

12/137303
Inventors:

Tony Libera - Tempe AZ, US
Peter Zeiner - Scottsdale AZ, US
Assignee:

Honeywell International Inc. - Morristown NJ
International Classification:

F02C 7/277
F02C 7/32
F02C 6/08
US Classification:

60788, 60 39183, 60802
Abstract:

A bi-modal turbine assembly is provided for use in conjunction with a gas turbine engine. In one embodiment, the bi-modal turbine assembly includes a housing assembly having a flow passage therethrough, a turbine wheel rotatably mounted in the housing assembly and positioned so as to be driven by pressurized air flowing through the flow passage, an output shaft rotatably mounted in the housing assembly, and first and second gear trains disposed in the housing assembly. A switching device is also disposed in the housing assembly and configured to mechanically couple: (i) the first gear train between the turbine wheel and the output shaft in a first operational mode, and (ii) the second gear train between the turbine wheel and the output shaft in a second operational mode.

Filed:

Nov 18, 2004
Appl. No.:

10/993335
Inventors:

William Giesler - Phoenix AZ, US
Jennifer Zonneveld - Phoenix AZ, US
Todd Dobbins - Scottsdale AZ, US
Betty Kocsis - Phoenix AZ, US
Peter Zeiner - Scottsdale AZ, US
International Classification:

F04D 29/08
US Classification:

415111000
Abstract:

A stator seal assembly is provided that includes a seal case, an O-ring and a stator ring. The seal case has an inner peripheral wall, an outer peripheral wall, and an annular cavity formed therebetween. The O-ring is coupled to the seal case inner peripheral wall and disposed in the annular cavity, and is constructed of a material having stress versus strain ratio of less than about 5 ksi and a Shore M value of between about 30 and 50. The stator ring is disposed within the seal case annular cavity.

US Patent:

20120266606, Oct 25, 2012
Filed:

Apr 20, 2011
Appl. No.:

13/090905
Inventors:

Peter Kenneth Zeiner - Scottsdale AZ, US
Dave Oman - Chandler AZ, US
Jimmy Wiggins - Chandler AZ, US
Assignee:

HONEYWELL INTERNATIONAL INC. - Morristown NJ
International Classification:

F02C 7/277
US Classification:

60788
Abstract:

An air turbine start system is provided that includes an air turbine starter, a starter air valve, a turbine speed sensor, and a circuit. The starter air valve is movable between an open position, in which the pressurized air may flow into the air turbine starter, and a closed position, in which pressurized air does not flow into the air turbine starter. The turbine speed sensor is coupled to the air turbine starter, and is configured to sense the rotational speed of the turbine and supply a rotational speed signal representative thereof. The circuit is coupled to receive the rotational speed signal and is configured, upon receipt thereof, to determine whether the starter air valve is in the closed position or an open position.

Appl. No.:

15/194900
Inventors:

- Morris Plains NJ, US
Peter Kenneth Zeiner - Scottsdale AZ, US
Assignee:

HONEYWELL INTERNATIONAL INC. - Morris Plains NJ
International Classification:

F02C 7/277
F02C 7/20
Abstract:

An air turbine starter includes a support structure and a turbine having a shaft and a rotor that extends away from the shaft in a radial direction. The air turbine starter also includes a mount structure that supports the turbine for rotation relative to the support structure. The mount structure is configured to transfer a force from the turbine to the support structure. The mount structure includes a deformable member that is configured to deform when the force exceeds a predetermined threshold.
