STEAM TURBINE INNER CASING COMPONENT AND REPAIR METHOD THEREFOR
Embodiments of the present invention relate to an inner casing component configured to form part of a steam flow path of a last stage of an axial flow steam turbine, the steam turbine inner casing component having a base made of nodular cast iron and a coating, on the base, in a region exposed to the steam flow path, consisting of manganese austenitic steel.
AIRCRAFT ENGINE WITH AN IMPACT PANEL
A facing sheet for a fan casing comprising a support layer that includes a set of partitioned cavities with open faces and a facing sheet comprising a polymer matrix composite having a nanostructure.
CERAMIC MATRIX COMPOSITE TURBINE VANE AND METHOD FOR MAKING
A turbine vane comprising ceramic matrix composite materials includes a vane support core, an airfoil, and an end wall that at least partially defines a gas path. The turbine vane is formed from a plurality of ceramic plies or preforms that are infiltrated with ceramic matrix material to form a one-piece ceramic matrix composite turbine vane.
ATTACHMENT REGION FOR CMC COMPONENTS
A component for a gas turbine engine includes a component body formed of ceramic matrix composite lamina and has at least one hook. The at least one hook has an attachment region radially inward of the at least one hook. The attachment region is radially thinner from a hook end of the at least one hook to a remote end, and then becomes radially thicker. A slot is formed through a radial thickness of the at least one hook from the hook end in a remote direction, such that there are two sections of the attachment region. A gas turbine engine is also disclosed.
ROTARY ASSEMBLY FOR A TURBINE ENGINE COMPRISING A SELF-SUPPORTED ROTOR COLLAR
A rotary assembly for a turbine engine is provided. The assembly includes a rotor with two consecutive rotor stages equipped with a plurality of movable vanes, and an annular rotor shroud connecting the two consecutive rotor stages; and a stator including a stator stage, provided with a plurality of fixed vanes and disposed between the two rotor stages, and an annular stator ring mounted on the fixed vanes. Either the rotor shroud or the stator ring bears at least one wiper designed to cooperate with an abradable track on the other of the rotor shroud and stator ring, such that the rotor shroud includes at at least one of its upstream or downstream ends an inclined contact portion resting on an inclined bearing surface of the corresponding rotor stage, the bearing surface being the outer surface of a projection extending from a base portion of the corresponding rotor stage.
HEAT SHIELDING COATING AND TURBINE MEMBER
A heat shielding coating (11) includes a bond coat layer (12) as a metal coupling layer laminated on a base material (10), and a top coat layer (13) which is laminated on the bond coat layer (12) and includes zirconia-based ceramic, in which the top coat layer (13) has a porosity of 9% or less.
