  • Patent number: 10927767
    Abstract: An exoskeletal gas turbine engine having a rotatable outer shaft and an inner stationary case enclosed in a casing. The engine comprises a compressor section at an inlet end, a combustor section, and a turbine section at an outlet end. Rotating compressor blades and turbine blades are attached to, and extend radially inward from, an inner surface of the outer shaft. Stationary vanes are attached, and extend radially outward from, an outer surface of the inner stationary case. The outer shaft rotates around a front bearing and a rear bearing. An inlet compressor blade arrangement is attached to the outer race of the front bearing. An outlet turbine blade arrangement is attached to the outer race of the rear bearing. The inner race of the front and rear bearings attach to the inner stationary case.

  • Patent number: 10767864
    Abstract: A gas turbine engine may include a combustor having an inner wall and an outer wall defining a combustion chamber there between. The inner wall and the outer wall may each have at least one opening into the combustion chamber. The gas turbine engine may also include at least one mobile conduit through which a cooling fluid may flow. The mobile conduit may pass through the combustion chamber from the at least one opening in the outer wall to the at least one opening in the inner wall. The gas turbine engine may further include a first joint and a second joint fluidly connecting the mobile conduit to the at least one opening in the inner wall and the at least one opening in the outer wall, respectively. The first joint and the second joint may enable multiple degrees of freedom of the mobile conduit within the combustion chamber.

  • Patent number: 10738649
    Abstract: A reinforced oxide-oxide CMC component for a gas turbine engine includes a composite body and a structural element embedded in the composite body, where the composite body comprises a 2D oxide-oxide composite and the structural element comprises a 3D oxide-oxide composite. The 2D oxide-oxide composite includes 2D woven or nonwoven oxide fibers in a first oxide matrix, and the 3D oxide-oxide composite includes 3D woven oxide fibers in a second oxide matrix. The first oxide matrix and the second oxide matrix may comprise the same or a different oxide.

  • Patent number: 10208668
    Abstract: A cooling system for a gas turbine is provided that may include a drive shaft, a shield of a combustor of the gas turbine engine, and a conduit. The drive shaft may be configured to mechanically couple a compressor of the gas turbine engine to a turbine of the gas turbine engine. The shield may be positioned between the compressor and the turbine. The combustor may be configured to drive the turbine. The conduit may be configured to supply a cooling fluid to a gap between an outer surface of the drive shaft and the shield of the combustor.

  • Publication number: 20110202777
    Abstract: An information handling system can receive power from a wireless or wired power source. In response to determining the information handling system is coupled to the wired power source, the system decouples the wireless power source from providing power. In response to the system being decoupled from the wired power source, the information handling system couples the wireless power source to the system.
