A misting fan system includes a fan and a mister positioned above the fan. The fan includes a motor and a plurality of fan blades operably coupled thereto. Each of the fan blades comprises a base member and a paddle member mated to the base member, and each paddle member comprises an upper surface and a lower surface. A hydrophobic coating may be applied to at least one of the upper surface and the lower surface of the paddle member of at least one of the plurality of fan blades.

An acoustic liner includes a first face sheet, a second face sheet spaced from the first face sheet, and a plurality of sidewalls extending between the first face sheet and the second face sheet. The plurality of sidewalls defines a plurality of cells. Each cell of the plurality of cells defines a cavity between the first face sheet and the second face sheet. A bulk absorber is disposed within at least one cell of the plurality of cells. The bulk absorber further defines the cavity of the at least one cell of the plurality of cells. The first face sheet defines a plurality of apertures extending through a thickness of the first face sheet. Each aperture of the plurality of apertures is aligned with a respective cell of the plurality of cells.

A supercharger assembly includes rotors, a base plate, and a housing with an anti-fouling material on one or more surfaces where accumulation of soot and/or soot-like material may lead to mechanical friction and possibly seizing. The anti-fouling material can have oleophobic and/or hydrophobic properties.

A coated gas turbine engine part includes a substrate and a calcium-magnesium-alumino-silicate CMAS protection layer present on the substrate. The layer includes a first phase of a calcium-magnesium-alumino-silicate CMAS protection material and a second phase including particles of an anti-wetting material dispersed in the first phase.

The invention relates to an anti-icing turbomachine blade (26), in particular for a low-pressure compressor or an intermediate-pressure compressor of a turbomachine. The blade (26) has a leading edge (28) formed by an ice-phobic surface (40) and two hydrophobic surfaces (42; 44) which extend the ice-phobic surface (40) on the pressure side (32) and the suction side (34) to allow water droplets escaping from the leading edge (28) to flow.

A pressure sensing device with a tubular pressure port including an internal chamfer adjacent to a deflectable diaphragm, and/or a hydrophobic or superhydrophobic coating applied to at least a portion of the tubular pressure port, the internal chamfer, and/or the deflectable diaphragm. The internal chamfer and/or the hydrophobic or superhydrophobic coating are configured at least in part to reduce adhesive forces between condensation and the surface of the tubular pressure port, to reduce the tendency for capillary action to draw condensation towards the deflectable diaphragm, and/or to increase the tendency for capillary action or gravity to draw condensation away from the deflectable diaphragm and out of the tubular pressure port.

A combustion engine component is disclosed. The combustion engine component comprises a body that includes a first surface in operative thermal communication with a hot combustion gas, and a second surface in operative fluid communication with a cooling fluid. Also, as disclosed in greater detail below, the second surface includes a first surface contour feature configured to increase a contact angle of a liquid on the second surface.

A fan section to be incorporated into a gas turbine engine has a rotor and a plurality of fan blades. The fan blades deliver air into a bypass duct defined inwardly of the nacelle and into a core engine. There are static vanes inward of the nacelle. A surface of the fan section is provided with a removable film material. A gas turbine engine and a method of refurbishing a surface are also disclosed.

A pressure sensing device with a tubular pressure port including an internal chamfer adjacent to a deflectable diaphragm, and/or a hydrophobic or superhydrophobic coating applied to at least a portion of the tubular pressure port, the internal chamfer, and/or the deflectable diaphragm. The internal chamfer and/or the hydrophobic or superhydrophobic coating are configured at least in part to reduce adhesive forces between condensation and the surface of the tubular pressure port, to reduce the tendency for capillary action to draw condensation towards the deflectable diaphragm, and/or to increase the tendency for capillary action or gravity to draw condensation away from the deflectable diaphragm and out of the tubular pressure port.

This invention relates generally to an article that includes a non-wetting surface having a dynamic contact angle of at least about 90. The surface is patterned with macro-scale features configured to induce controlled asymmetry in a liquid film produced by impingement of a droplet onto the surface, thereby reducing time of contact between the droplet and the surface.
