摘要:
Methods allowing for visual inspection of a coated component for erosion damage involving providing a component, and applying a plurality of layers of an erosion system to at least a portion of the component to produce the coated component where each layer of the erosion system comprises a different color that becomes visible as the layer is eroded.
摘要:
An assembly includes a unitary nacelle structure and an integrated fan housing for a gas turbine engine assembly. The unitary nacelle structure includes an inlet region and a fan cowl region, and is configured to at least partially circumscribe the integrated fan housing. The integrated fan housing comprises an integral composite structure and includes a fan case sized and configured for encircling a fan blade assembly of an associated gas turbine engine, a fan hub, and a plurality of fan outlet guide vanes. The unitary nacelle structure cooperates with the integrated fan housing to transfer static and dynamic loads directly to a support structure, rather than through the engine core, to minimize backbone bending.
摘要:
An erosion system including a toughened resin for improving erosion resistance, the toughened resin including a resin and a toughening agent, and a support for retaining the toughened resin where at least one layer of the erosion system is applied to a component to provide from about a 50% increase to about a 400% increase in erosion resistance to the component per layer of the erosion system.

摘要:
Methods for making components having improved erosion resistance including providing a component having a surface, applying at least one layer of an erosion system to at least a portion of the surface of the component, each layer of the erosion system containing a support, and a toughened resin applied to the support, and co-molding the component having the applied erosion system to produce a coated component having from about a 50% increase to about a 400% increase in erosion resistance per layer of the erosion system.
摘要:
An enclosure having at least one wall, the wall includes an inner panel comprising, in sequence outwardly from the enclosure hollow interior, an inner sheet comprising a plurality of perforations extending therethrough, a plurality of panel stiffening members coupled to the inner sheet, and at least one inner panel sound absorption member comprising non-metallic sound absorption material positioned between adjacent of the plurality of panel stiffening members, and an outer panel comprising in sequence inwardly from outside of the enclosure, an outer panel sandwich member comprising non-metallic composite material including spaced-apart first and second walls and a plurality of spaced-apart transverse walls extending between the first and second walls defining hollow chambers therebetween, the outer panel coupled to the inner panel such that an outer surface of the inner panel is substantially flush against an outer surface of the outer panel.
