Aspects of the disclosure are directed to a flexible thermal blanket assembly, comprising: a stack-up of material layers that are configured to wrap around a component, a plurality of snaps configured to be mechanically fastened through the material layers, and a cap configured as a baffle to prevent thermal energy located at an exterior of the thermal blanket assembly from entering an interior of the thermal blanket assembly when the thermal blanket assembly is assembled.

Provided is a gas turbine system including: a compressor that compresses external air to generate compressed air; a combustor that burns the compressed air generated by the compressor together with fuel to generate a combustion gas; a turbine driven by the combustion gas generated by the combustor; an exhaust unit that guides a combustion gas that has passed through the turbine to outside; a nacelle formed in a cylindrical shape and extending along an axis line about which the turbine rotates and arranged so as to cover the compressor, the combustor, the turbine, and the exhaust unit; and an exit unit that guides the combustion gas, which passed through the turbine, to a discharge port provided in the surface of the nacelle.

A vane device for a gas turbine is provided. The vane device includes a first airfoil having a first suction side and a first pressure side, a second airfoil having a second suction side and a second pressure side, an inner shroud and an outer shroud. The first airfoil and the second airfoil are arranged between the inner shroud and the outer shroud, wherein the first airfoil and the second airfoil are at least partially coated with a MCrAlY coating. At least the first suction side has a first coated surface section which is coated with a thermal barrier coating and which represents at least a part of the total surface of the first suction side. At least the inner shroud or the outer shroud has a further coated surface section which is coated with a further thermal barrier coating. A corresponding method of manufacturing is also provided.

A corrugated shield comprises a mounting base and a corrugated ring section. The mounting base is disposed at an aft end of the ring section for securing the shield ring section within a generally annular cavity. The generally annular cavity is defined at least in part by a hot fluid flow path boundary wall, and a radially adjacent and spaced apart cold fluid flow path boundary wall. The corrugated ring section is configured to substantially block a line of sight between the hot fluid flow path boundary wall and the cold fluid flow path boundary wall.
