The method includes forming an inner blade pattern, the inner blade pattern including an inner spar and a plurality of inner spar cooling fins. The method also includes forming an inner blade core, removing the inner blade pattern from the inner blade core, forming an outer blade pattern, forming a casting shell, removing the outer blade pattern from the casting shell, and casting the cooled turbine blade in the casting shell. The method also includes removing the casting shell from the cast cooled turbine blade, and removing the inner blade core from the cast cooled turbine blade.
Abstract:
A gas turbine engine (100) variable nozzle (460) includes an outer shroud (461), an inner shroud (462), a variable nozzle airfoil (463), and a position selector (470). The inner shroud (462) is located radially inward from the outer shroud (461). The variable nozzle airfoil (463) extends radially between the outer shroud (461) and the inner shroud (462). The variable nozzle airfoil (463) includes a vane shaft (464) extending radially outward from the variable nozzle airfoil (463) through the outer shroud (461). The position selector (470) is coupled with the variable nozzle airfoil (463) to fixedly lock the variable nozzle airfoil (463) into one of a plurality of preselected positions.
Abstract:
A diffuser for use in a gas turbine engine, the diffuser having a first wall, a second wall, and a flow separator. The first and second wall define an annular cavity, with the annular cavity having an inlet. The first and second wall also forming a prediffuser that is proximate the inlet, and a dump region distal the inlet. The flow separator extends from the first wall into the annular cavity.
Abstract:
A system for controlling an electric motor is disclosed herein. In particular, the system receives a user input indicative of a desired performance parameter for the electric motor. Based on the desired performance parameter, the system determines a control parameter that defines an operational range. The system then adjusts the electric motor according to the control parameter so that the electric motor generates constant output power over the operational range.
Abstract:
A bearing for a gearbox, the bearing having a cylindrical body. The cylindrical body defines a hollow interior chamber. The cylindrical body has a gear supporting section. The gear supporting section has a cross-section formed by three lobes equally distributed around a circumference of the cylindrical body. Each of the lobes has a land portion having a first radius over at least 20% of the lobe. Each lobe also has a tapered portion that gradually slopes from the first radius of the land portion to a reduced radius region that is smaller than the first radius. The tapered portion is formed over less than 80% of each lobe. Each lobe also has an opening formed in the reduced radius region and a flow passage fluidly connecting the hollow interior of the cylindrical body with the opening formed in the reduced radius region.
Abstract:
An imaging inspection system and inspection method for a combustion chamber of a gas turbine engine having an imaging inspection device and a controller. The imaging inspection device includes a combustor interface, an inspection head having a first camera, an inspection head extender, a roll actuator, and a pitch actuator. The controller is configured to manipulate the inspection head in a predefined sequence.
Abstract:
An aft clamp ring for a gas turbine engine is disclosed. The aft clamp ring includes a body, a forward sealing face, and an aft sealing face. The body includes an annular shape extending between an outer end and an inner end. The forward sealing face faces in a second axial direction. The aft sealing face is adjacent the outer end facing in a first axial direction and is at least partially radially aligned with the forward sealing face. The forward sealing face and the aft sealing face are each an annular surface with a surface area from 105.50 cm2 to 165.19 cm2.
Abstract:
A gas fuel delivery system is disclosed. A gas fuel delivery system includes a gas fuel system and a gas ring. The gas fuel delivery system includes an enclosure surrounding the gas fuel system. The enclosure includes a ventilation system. The enclosure includes fuel pipes connecting the gas fuel system to a fuel source and to a gas ring. Each fuel pipe includes an outer conduit and an inner conduit, wherein the inner conduit is enclosed by the outer conduit. The inner conduit is in fluid communication with the gas fuel system.
Abstract:
A system is provided for detecting and mitigating damage from flashback in a combustion system. The combustion system includes an injector and a combustor. The system includes a supply line coupled to the combustor. The supply line defines an end configured to face with the combustor. The end is provided with a fusible component that is configured to melt in the event of a flashback and release an extinguishing agent into the combustor.
