摘要:
A combustor basket (20) is provided comprising a generally tubular wall (22) defining a cavity (24) and a liner (26) of a ceramic matrix composite material disposed within the cavity (24), wherein an interference fit exists between an outer surface (34) of the liner (26) located in the cavity (24) and an inner surface (28) of the generally tubular wall (22). Advantageously, the novel combustor basket (20) greatly reduces the amount of air or other medium needed to cool the combustor basket body and increases the maximum allowable flame temperature that the combustor basket (20) can withstand. A method of manufacturing the combustor basket (20) is also provided.
摘要:
A transition duct support system for a transition duct that channels hot gases from a combustor exit to a gas turbine inlet of a turbine engine. The transition duct support system includes a transition support frame formed from a body positioned around a transition duct body at an outlet transition section. The transition support frame may include a first inner surface aligned with and positioned proximate to portion of the outlet transition section that is positioned at an oblique angle relative to the outer wall of the transition duct body to limit linear movement of the transition duct body in a first direction. The transition support frame may also include a second inner surface positioned at an oblique angle to limit linear movement of the transition duct body in a second direction opposite the first direction.
摘要:
Aspects of the invention relate to a system and method for introducing fuel to the flow of air along a surface upstream of a combustion area. Fuel injectors can be used to deliver fuel to the air flow at or near the boundary layer of the air flow. The fuel injectors are ideally located substantially outside of the flow path. Many benefits can be realized by keeping the injectors out of the flow path including avoidance of potential excitations and smaller pressure drops in the flow. The potential of flame from the combustion area traveling upstream to the fuel injector can be minimized by creating a disturbance in the boundary layer of the flow downstream of the fuel injectors. Such disturbances can be achieved by placing a turbulence generator in the boundary layer. The turbulence generator can be a surface protrusion or a fluid cross-flow.

摘要:
An attachment device for coupling one or more removable turbine components to a carrier of a turbine engine. The attachment device may include a securement structure rotatable about an axis of rotation and including one or more arms for grasping an arm extending from a support structure. A fastener may extend from the support structure and be inserted into a fastener receiving recess in the securement structure for preventing the securement structure from rotating and becoming disengaged from the support structure. The attachment device may also include a fastener retaining device for preventing the fastener, which may be a threaded bolt, from becoming disengaged from the attachment device, traveling downstream in a turbine, and damaging a turbine assembly.
