A panel for machinery enclosure, particularly for turbomachine enclosures. More specifically, a multilayered panel including several different layers each performing a specific function. In particular, the multilayered panel is capable to provide high levels of jet fire and fire/blast protection together with high performances in term of noise abatement with a lighter structure with respect to the panels of the prior art.

Multilayered panel for machinery enclosure

A silicide-based composite material is disclosed, comprising a silicide of Mo, B, W, Nb, Ta, Ti, Cr, Co, Y, or a combination thereof, Si3N4, and at least an oxide, as well as and a process for producing the same.

Silicide-based composite material and process for producing the same

A fixing system for a panel, particularly for a noise absorption panel, including an omega stringer having a substantially omega-shaped cross-section, wherein the omega stringer includes a central portion and two lateral foot portions; a flat bar longitudinally directly connected to the central portion of the omega stringer; a sealing gasket arranged longitudinally onto the lateral foot portions of the omega stringer or onto the flat bar; wherein height of omega stringer is selected so that, when a panel is clamped between the omega stringer and the flat bar, the sealing gasket is compressed between panel and fixing system.

Fixing system for panels and turbomachine enclosure comprising such system

An automatic ring valvecomprising a valve seatprovided with a plurality of gas flow passagesarranged according to at least one annular row, at least a shuttercomprising at least one ring-shaped portion for selectively closing and opening the gas flow passages, wherein said ring-shaped portion of the shuttercomprises a fiber-reinforced matrix, at least one contrasting member for contrasting an opening movement of ring-shaped portion of the shutter, wherein said ring-shaped portion of the shuttercomprises a structural coreA made by said fiber-reinforced matrix, and wherein at least a portion of said structural coreA is covered by at least one primary layerB, designed to improve fracture and/or impact and/or wear resistance of said ring-shaped portion.
