Filed:

Apr 26, 2004

Appl. No.:

10/832932

Inventors:

Charles S. Lo - Glendale AZ, US

Assignee:

Honeywell International, Inc. - Morristown NJ

International Classification:

F04D 29/44

US Classification:

4151994, 4151996, 7386214

Abstract:

A modular waterbrake that can be used with differing types and sizes of rotating machines includes common end stages, and a plurality of common intervening power stages. Each power stage will extract a certain amount of shaft horsepower from the machine under test, and each stage operates independently of one another. Thus, the modular water dynamometer can be used to zero in on desired torque test loads during machine testing, by simply activating or deactivating selected stages.

10/160559

Inventors:

Charles S. Lo - Glendale AZ, US

Assignee:

Honeywell International, Inc. - Morristown NJ

International Classification:

G01L 3/20

US Classification:

7386214

Abstract:

A waterbrake dynamometer fluid volumetric control system and method includes a closed-loop recirculation passage to maintain a substantially constant fluid volume within the waterbrake. Fluid volume within the waterbrake is controlled by selectively supplying fluid to, and removing fluid from, the waterbrake.

International Classification:

F02C 6/08
F02C 7/12
F02K 3/02

US Classification:

602263, 60262, 60785, 60806

Abstract:

A system for directing air flow to separate plena of a compartment that is defined at least by a compartment wall includes a NACA scoop, and a Pitot scoop. The NACA scoop is formed in the compartment wall, and includes two side walls, a bottom wall, and an entrance lip that is defined by the compartment wall and is spaced apart from the bottom wall to form a NACA scoop air inlet. The Pitot scoop is longitudinally aligned with the NACA scoop, includes a Pitot scoop air inlet, a Pitot scoop air outlet, and a Pitot scoop flow passage.

Appl. No.:

13/358161

Inventors:

Charles Lo - Peoria AZ, US

Assignee:

HONEYWELL INTERNATIONAL INC. - Morristown NJ

International Classification:

F02C 6/08

US Classification:

60785

Abstract:

A system for supplying turbine cooling air flow includes a turbofan engine, a heat exchanger, and a door. The turbofan engine includes an engine case that has an inner volume within which at least a gas turbine engine is mounted, and a bypass flow passage that is defined by an outer fan duct and an inner fan duct and that is configured to direct fan air flow therethrough. The heat exchanger is disposed within the turbofan engine, is coupled to receive fluid and cooling air from the bypass flow passage, and is configured to transfer heat between fluid and the cooling air. The door is movably mounted in the turbofan engine and is movable between a closed position, in which the cooling air will not flow through the heat exchanger, and an open position, in which the cooling air may flow through the heat exchanger.

F28F 13/12

US Classification:

415177, 165175, 1651091, 21912163

Abstract:

A heat exchange system includes a first flow passage and a second flow passage. The heat exchange system is configured to transfer heat between a first fluid flowing through the first flow passage and a second fluid flowing through the second flow passage. The first flow passage includes an inlet header, a plurality of tubes, and an outlet header. The inlet header includes a plurality of header-tube transition portions configured to allow the first fluid to flow from the inlet header and into the tubes, the plurality of header-tube transition portions each including a smoothly curved inlet portion and a tapered tube connection portion.

Inventors:

Charles Lo - Peoria AZ, US

Assignee:

HONEYWELL INTERNATIONAL INC. - Morristown NJ

International Classification:

F02C 7/18

US Classification:

60806

Abstract:

A system for selectively supplying air between separate plena of a gas turbine engine includes a gas turbine engine, a door, and a bi-metallic door actuator. The gas turbine engine comprises at least a first plenum and a second plenum, and has an opening between the first plenum and the second plenum. The is door mounted in the gas turbine engine and is movable between a closed position, in which air is prevented from flowing through the opening, and an open position, in which air may flow though the opening. The bi-metallic door actuator is coupled to the door and is configured to selectively move the door between the closed position and the open position.
