Abstract: A system includes an airfoil disposed inside an engine assembly that includes a pressure side and a suction side that are coupled together at a leading edge and a trailing edge. The airfoil extends a radial length away from a central axis of the engine assembly between a hub end and a tip end. The airfoil includes a sweep feature disposed at the leading edge that is shaped to alter the air inside the engine assembly. Altering the air inside the engine assembly reduces a surface unsteady pressure level on the airfoil. The system includes a fan frame assembly comprising an inner and outer surface. The hub end is coupled with the inner surface and the tip end is coupled with the outer surface. The airfoil is integrated with the fan frame assembly such that the airfoil increases a structural load supporting capability of the fan frame assembly.

Abstract: Systems and methods for graphically representing a deployment process of a development environment are described. A request to create a development environment is received from a user. The request is evaluated to identify a stored template appropriate for the requested development environment, and the identified stored template is parsed to identify a plurality of executable instructions. A graphical depiction of the executable instructions is generated for display on a display device coupled to a development environment deployment system. Upon receipt of an updated status of an executable instruction from a virtual machine host coupled to the development environment deployment system, the graphical depiction of the executable instructions is modified.

Abstract: Systems and methods for logging events in the deployment of a development environment are disclosed. An interactive graphical depiction of executable instructions for creating a development environment is generated for display on a display device coupled to a development environment deployment system. An updated status of an executable instruction is received from a virtual machine host coupled to the development environment deployment system. The interactive graphical depiction of the executable instructions is modified in response to the receipt of the updated status. A selection of an executable instruction displayed within the interactive graphical depiction is received from the user. Responsive to the selection, log entry associated with the selected executable instruction is presented for display.

Abstract: A system includes plural airfoils operably coupled with a rotatable member of an aircraft engine system. The rotatable member is configured to rotate about an axial centerline of the aircraft engine system. The system comprises a feature at one or more exterior locations of an aircraft body. The feature is shaped to alter a flow of air between the aircraft body and the airfoils. Altering the flow of air also one or more of reduces a local load on the airfoils, reduces a local angle of attack of the airfoils, or reduces a noise level that is generated by the aircraft engine system as the rotatable member rotates about the axial centerline of the aircraft engine system relative to the aircraft body not including the feature.

Abstract: Systems and methods for deploying development environments are described. A request to create a development environment is received from a user. The request is evaluated to identify a stored template appropriate for the requested development environment. An instruction sequence is then generated to create the requested development environment, based on the determined template. The instructions in the instruction sequence are transmitted to multiple virtual machine hosts. Upon successful creation of the development environment, a response is returned to the requesting user with access information for the development environment.
