Patent number: 11201524Abstract: A system can include a compressor outlet line configured to receive compressor outlet flow from a compressor, a bypass line in fluid communication with the compressor outlet line and a motor outlet line to divert a bypass flow of the compressor outlet flow. The system can include at least one pump in fluid communication between the bypass line and the motor outlet line such that the bypass flow at least partially drives the pump to pull cooling flow through a motor to cool the motor.Type: GrantFiled: June 26, 2019Date of Patent: December 14, 2021Assignee: Hamilton Sundstrand CorporationInventors: Debabrata Pal, John H. Paliulis, Christina W. Millot

Patent number: 10035225Abstract: A thrust plate includes an annular-shaped body having a scalloped outer edge that forms a first circumference defined by a first diameter. The thrust plate further includes a plurality of cooling slots formed in a first surface of the body. The cooling slots are formed between each pair of adjacent scallops. A center of each cooling slot extends towards the center of the thrust plate at a common predetermined angle with respect to one another.Type: GrantFiled: July 15, 2015Date of Patent: July 31, 2018Assignee: HAMILTON SUNDSTRAND CORPORATIONInventors: Darryl A. Colson, Craig M. Beers, John H. Paliulis

Patent number: 8734017Abstract: An air bearing shaft for an air cycle machine is provided. The air bearing shaft includes a seal disk and a shaft body. The shaft body includes a first shaft body portion extending from a face of the seal disk to a knife-edge seal. The first shaft body portion includes journal bearing cooling holes positioned axially closer to the knife-edge seal than to the face of the seal disk. The journal bearing cooling holes extend through the first shaft body portion to a hollow interior and have a total cooling area. Start-up holes are positioned axially closer to the face of the seal disk than to the knife-edge seal. The start-up holes extend through the first shaft body portion to the hollow interior. The start-up holes have a total start-up area. A ratio of the total cooling area to the total start-up area is between 2.17 and 4.06.Type: GrantFiled: March 8, 2013Date of Patent: May 27, 2014Assignee: Hamilton Sundstrand CorporationInventors: Darryl A.
