Patent number: 11840968Abstract: An aspect includes a method for motoring control for multiple engines of an aircraft is provided. A controller can determine a motoring time of a first engine starting system to cool a first engine. The controller can compare the motoring time of the first engine starting system with a motoring time of one or more other engine starting systems of one or more other engines of the aircraft. The motoring time of the first engine starting system can be controlled relative to a tolerance of the motoring time of the one or more other engine starting systems by adjusting the motoring time of the first engine starting system relative to the one or more other engine starting systems in a motoring sequence based on comparing the motoring time of the first engine starting system with the motoring time of the one or more other engine starting systems.Type: GrantFiled: September 27, 2021Date of Patent: December 12, 2023Assignee: RTX CORPORATIONInventors: Matthew D. Teicholz, James W. Dunn, Christopher P. Kmetz, Louis A. Celiberti

Patent number: 11142329Abstract: An aspect includes a system for pre-start motoring control for multiple engines of an aircraft. The system includes a first engine starting system of a first engine and a controller. The controller is operable to control a motoring time of the first engine starting system relative to one or more other engine starting systems of one or more other engines of the aircraft by adjusting the motoring time of the first engine starting system within a tolerance of the motoring time of the one or more other engine starting systems in a pre-start motoring sequence.Type: GrantFiled: March 9, 2020Date of Patent: October 12, 2021Assignee: RAYTHEON TECHNOLOGIES CORPORATIONInventors: Matthew D. Teicholz, James W. Dunn, Christopher P. Kmetz, Louis A. Celiberti

Patent number: 10618666Abstract: An aspect includes a system for pre-start motoring synchronization for multiple engines of an aircraft. The system includes a first engine starting system of a first engine and a controller. The controller is operable to synchronize a motoring time of the first engine starting system with one or more other engine starting systems of one or more other engines of the aircraft by extending the motoring time of the first engine starting system to match, within a synchronization tolerance, the motoring time of the one or more other engine starting systems in a pre-start motoring sequence.Type: GrantFiled: July 21, 2016Date of Patent: April 14, 2020Assignee: UNITED TECHNOLOGIES CORPORATIONInventors: Matthew D. Teicholz, James W. Dunn, Christopher P. Kmetz, Louis A. Celiberti

Patent number: 9239117Abstract: One embodiment of the seal housing for a face seal described herein include a base with a seal element support and a shroud both extending from the base in a common direction. The seal element support and the base define a space for receiving a seal element. The shroud includes a tip having a head portion that tapers toward a neck portion that is reduced in size relative to the head portion. The tip is secured to a stem of the shroud through a set of circumferentially distributed countersunk holes.Type: GrantFiled: September 11, 2015Date of Patent: January 19, 2016Assignee: United Technologies CorporationInventors: Colin D. Craig, Enzo DiBenedetto, Christopher P. Kmetz, Jonathan Logan Miller, Mark R. Sondeen
