US Patent:

7335999, Feb 26, 2008
Filed:

Jun 15, 2004
Appl. No.:

10/869552
Inventors:

Calvin C. Potter - Mesa AZ, US
David M. Eschborn - Gilbert AZ, US
Assignee:

Honeywell International, Inc. - Morristown NJ
International Classification:

F03B 13/12
F03B 13/00
H02P 9/04
US Classification:

290 43, 290 54
Abstract:

A fluid-powered actuator assembly is modified to include a low power generator. The low power generator rotates in response to a drive force received from the actuator assembly, and thus only generates electrical power when the actuator assembly is operating. The low power generator is used to supply electrical power to various sensors and circuits, which may be used to implement prognostic and health monitoring capabilities for the actuator assembly.

US Patent:

7441642, Oct 28, 2008
Filed:

Oct 19, 2005
Appl. No.:

11/254087
Inventors:

Michael J. Calmelat - Chandler AZ, US
David M. Eschborn - Gilbert AZ, US
Assignee:

Honeywell International Inc. - Morristown NJ
International Classification:

F16D 41/061
F16D 41/067
US Classification:

192 45, 192 561, 192 65, 464 36
Abstract:

A clutch assembly is provided that includes a rotor, a stator, a clutch element disposed between the rotor and stator, and an axial force source. First and second contact surfaces are disposed on the rotor and spaced axially apart. The second surface has a smaller radial distance to a rotor rotational axis than the first surface. The axial force source is in communication with the clutch element and is configured to supply a predetermined axial force to the clutch element. When an opposing axial force is applied to the clutch element, the assembly selectively (i) engages by providing contact between the clutch element and the first clutch element contact surface, when the opposing force is less than the predetermined axial force, and (ii) disengages by providing contact between the clutch element and the second clutch element contact surface, when the opposing force is greater than the predetermined axial force.

Filed:

Oct 28, 2005
Appl. No.:

11/262058
Inventors:

David M. Eschborn - Gilbert AZ, US
Guy L. Dilno - Chandler AZ, US
Michael J. Calmelat - Chandler AZ, US
Assignee:

Honeywell International Inc. - Morristown NJ
International Classification:

F02K 1/54
US Classification:

60204, 602262, 244110 B, 23926529
Abstract:

A thrust reverser actuation system is provided that includes a synchronization system that synchronizes the actuation of at least two actuators coupled to at least two power drive units. The synchronization system includes a first synchronization shaft coupling the first power drive unit to the second power drive unit and a second synchronization shaft coupling the first power drive unit to the second power drive unit. The at least two actuators are adapted to receive a drive force and configured, in response to receipt of the drive force, to move between a stowed position and a deployed position. The synchronization system is configured to transfer power between the first power drive unit and the second power drive unit, thereby eliminating a mismatch in power and provide uniform deployment of the at least two actuators.

Appl. No.:

12/165408
Inventors:

Michael J. Calmelat - Chandler AZ, US
David M. Eschborn - Gilbert AZ, US
Cal Potter - Mesa AZ, US
Kevin K. Chakkera - Chandler AZ, US
Assignee:

Honeywell International Inc. - Morristown NJ
International Classification:

F02K 1/76
US Classification:

701100, 602262, 60232
Abstract:

A fluid-powered thrust reverser actuation speed control system and method are provided. A drive fluid is supplied to a fluid-powered drive mechanism that is coupled to a thrust reverser movable component to thereby move the thrust reverser movable component at a first movement speed. A determination is made as to when the thrust reverser movable component attains a predetermined position. In response to the thrust reverser movable component attaining the predetermined position, the drive fluid supplied to the fluid-powered drive mechanism is controlled to thereby move the thrust reverser movable component at a second movement speed that is less than the first movement speed.
