Filed:

Jul 25, 2000

Appl. No.:

09/625700

Inventors:

Robert S. McCarty - Phoenix AZ
Glen T. High - Bramhall Stockport, GB

Assignee:

Honeywell International, Inc. - Morristown NJ

International Classification:

F02C 926

US Classification:

60773

Abstract:

A fuel system for delivering fuel from a fuel source to combustor in a gas turbine engine has a pump receiving fuel flow from the fuel source and producing a pressurized fuel flow that flows to a flow meter that measures the fuel flow and generates a signal thereof. A bypass valve bypasses, to the input side of the pump, a portion of the pressurized fuel flow before it reaches the flow meter. An electronic control unit is included that receives the signal and in response thereto adjusts the bypass valve until the measured fuel flow equals a predetermined desired fuel flow stored in the electronic control unit. The fuel system is also self-calibrating.

Honeywell International Inc. - Morristown NJ

International Classification:

F02C 7232

US Classification:

60 39094, 60 39281

Abstract:

A dual function rapid shutdown and ecology system for fuel delivery systems for engines, specially aircraft gas turbine engines, is disclosed. The dual function is accomplished in a single module operated by a single electro-magnetic solenoid valve commanded by the engine electronic control unit. Upon actuation of the solenoid valve, a large spring loaded piston strokes to the extreme of its travel creating a cavity having a volume sufficient to accommodate all fuel leftover in the fuel manifold and distribution system at shutdown, thus preventing atmospheric pollution or engine damage upon subsequent operation. Simultaneous with actuation of the solenoid valve, fuel pressure differentials cause a small piston to stroke to the extreme of its travel opening fuel passageways and causing all the fuel being delivered to the engine combustion chamber to be bypassed back to pump inlet, thus effectively accomplishing the rapid shutdown function. An alternate embodiment allows for use of the dual function system on engines employing low pressure differentials along the various stages of the fuel control system manifold or where the ecology function is not required.

Appl. No.:

7/238370

Inventors:

Robert S. McCarty - Phoenix AZ

Assignee:

Allied-Signal Inc. - Morris Township NJ

International Classification:

F02C 7232
F02C 926

US Classification:

60 3903

Abstract:

Methods for metering fluid flow and apparatus adapted for use with the methods. The apparatus (5) comprises an electrohydraulic solenoid (6) secured to and in fluid communication wiht a metering valve body (8). A cylindrical spool (15) is disposed in a channel (16) formed in the valve body (8), and variably blocks a flow path (74,90,75) extending through the valve body in response to variations in fluid pressure in a chamber (68) which is defined by the solenoid (6), the valve body (8), and the spool (15). Fluid is delivered to and vented from the chamber (68) through the solenoid (6), and the pressure in the chamber varies with the duty cycle of pulses communicated to the solenoid (6).
