A double walled stator housing includes a first stator housing wall, a second stator housing wall located radially outward from the first stator housing wall, and an air gap located between the first and the second stator housing walls. The housing also includes at least one support structure attached to the first stator housing wall and the second stator housing wall, spanning the air gap and configured to minimize heat transfer between the first wall and the second wall.

Turbomachine hollow blade (11) comprising at least one vane (14) having lateral walls (15) which are intended to guide a flow in a flow path around the vane and which are fixed to a first platform (12) at a first longitudinal end of the vane (14), the vane (14) further comprising an internal cavity between the lateral walls (15), which cavity is intended for passing a vane-cooling fluid, with a fluid inlet opening (19) opening through said first platform (12), characterized in that a gyroid surface network (18) fills at least part of the cavity, being arranged therein so as to guide the cooling fluid, and is in contact with at least part of the lateral walls (15).

An inlet filter housing includes a plurality of components that collectively form a complete filtering and conditioning system for filtering and conditioning a fluid along a housing flow path. Each component is fitted within an external structure of an International Organization of Standards (ISO) shipping container, which provides a rectangular cuboid enclosure. Each component includes operative structure of at least one of: a) only a portion of an axial extent of the filtering and conditioning system, and b) only a portion of a lateral cross-sectional area of the housing flow path.

A turbomachine blade assembly including a turbomachine blade (1), in particular for a gas turbine, and at least one tuning element container including a housing (10) attached to the turbomachine blade and an insert (20) disposed in a recess (11) of this housing. A wall (20; 21) of the insert spaces apart two first cavities (31), which each accommodate at least one tuning element (40) provided for impacting contact with the housing (10) and the insert (20).

A system may include a first duct including an air inlet end and an air outlet end, and a valve within the first duct and configured to open to allow or close to prevent fan duct air from the air inlet end to pass through to the air outlet end of the first duct. The system may also include a second duct including a first end and a second end. The first end of the second duct may be coupled to a sidewall of the first duct and configured to allow the fan duct air to flow from the first duct to the second duct. The system may also include a resonance chamber coupled to the second end of the second duct and configured to allow the air in the resonance chamber to act as a spring causing the air in the second duct to oscillate at a predefined frequency.

An oil distribution system including a shaft assembly, bearing assembly and mounting assembly is disclosed. The shaft assembly includes a shaft with an inner shaft. A pocket is defined between the shaft and the inner shaft. A ringed lattice containing oil is secured within the pocket, melting of the ringed lattice releases the oil. The shaft includes shaft slots to usher oil from the pocket towards the bearing assembly. The bearing assembly includes an inner and outer race. The inner and outer race each include axial slots and radial slots. The axial slots of the inner race align with the shaft slots to allow oil to flood the inner race. The mounting assembly includes a bearing support having bearing support slots to receive a stringed lattice. Oil from the bearing support flows into the outer race when the axial slots of the outer race align with the bearing support slots.

A hot section of a gas turbine engine includes a stator housing wall and an at least one insulating standoff attached to the stator housing wall, extending radially away from the stator housing wall. The hot section includes an accessory module attached to an opposite end of the at least one insulating standoff away from the stator housing wall.

A rotor assembly component which is a component of a gas turbine engine is provided with a rotor assembly component body made from a metal, and a hard particle layer including a mass of hard particles and a matrix material, with the hard particles being made from a material harder than a material forming the rotor assembly component body. The matrix material is made solely from the material forming the rotor assembly component body. The hard particle layer is supported directly on a surface of the rotor assembly component body.

Turbomachine hollow blade (11) comprising at least one vane (14) having lateral walls (15) which are intended to guide a flow in a flow path around the vane and which are fixed to a first platform (12) at a first longitudinal end of the vane (14), the vane (14) further comprising an internal cavity between the lateral walls (15), which cavity is intended for passing a vane-cooling fluid, with a fluid inlet opening (19) opening through said first platform (12), characterized in that a gyroid surface network (18) fills at least part of the cavity, being arranged therein so as to guide the cooling fluid, and is in contact with at least part of the lateral walls (15).
