A cost-effective method of forming a hydrophobic coating on a substrate and coated substrates are disclosed. Specifically, the method comprises applying amorphous powders of an alloy to the substrate through a cold spray process. Also provided is a novel type of hydrophobic coating made of metallic glasses or amorphous alloys. The hydrophobic coatings offer advantages such as, low cost, low maintenance, and high corrosion resistance.

A coating and related methods useful for reducing insect residue on moving surfaces, such as turbine blades or aircraft. The coating can include alternating layers of a perfluorinated acrylic copolymer and silicon dioxide nanoparticles that have been infused into one another via thermal annealing processes. The coating may be super-hydrophobic and exhibits desirable durability characteristics.

The disclosure relates to systems and methods that include coating a motor of an ESP with a DLC coating. The DLC coating includes a dopant and is hydrophobic. The coating can reduce (e.g., prevent) scale formation on the surface of the motor and/or reduce an amount of scale inhibitor chemical used to reduce scale.

An ice protection assembly on an airfoil includes a heater positioned on the leading edge, and one or more ice phobic layers positioned to inhibit runback ice formation on the surface of the airfoil downstream of the heater.

An air inlet section for an aircraft propulsion system nacelle includes an outer skin, an inner skin, and a lip skin. The lip skin extends between and to an outer end and an inner end. The outer end is disposed at the outer skin. The inner end is disposed at the inner skin. The lip skin forms an exterior lip skin surface extending from the inner end to the outer end. The exterior lip skin surface forms a leading edge of the lip skin. The exterior lip skin surface includes an outer surface portion and an inner surface portion. The outer surface portion extends from the outer end to the inner surface portion. The outer surface portion forms a hydrophobic surface. The inner surface portion extends from the inner end to the outer surface portion. The inner surface portion forms a hydrophilic surface.

The present disclosure provides an aircraft element including a leading edge section and a trailing edge section, and the leading edge section includes an anti-frost treatment device. This aircraft element is remarkable in that the trailing edge section includes a superhydrophobic surface.

A gas turbine having a wet compression device which allows droplets of an aqueous liquid mixture to be introduced into a compressor of the gas turbine during operation of the gas turbine, the aqueous liquid mixture containing at least one surfactant. The aqueous liquid mixture additionally contains at least a defoaming agent, and the gas turbine has a second metering device, which is designed to feed a predetermined quantity of defoaming agent into water which is provided for use in the wet compression device.

The present application provides a pulse filtration system for use with a compressor of a gas turbine engine. The pulse filtration system may include a pulse filter, a compressed air system in communication with the pulse filter, and a hydrophobic filter bag surrounding the pulse filter in whole or in part.

A fluid vapor distillation apparatus. The apparatus includes a source fluid input, and an evaporator condenser apparatus. The evaporator condenser apparatus includes a substantially cylindrical housing and a plurality of tubes in the housing. The source fluid input is fluidly connected to the evaporator condenser and the evaporator condenser transforms source fluid into steam and transforms compressed steam into product fluid. Also included in the fluid vapor distillation apparatus is a heat exchanger fluidly connected to the source fluid input and a product fluid output. The heat exchanger includes an outer tube and at least one inner tube. Also included in the fluid vapor distillation apparatus is a regenerative blower fluidly connected to the evaporator condenser. The regenerative blower compresses steam, and the compressed steam flows to the evaporative condenser where compressed steam is transformed into product fluid.

A ram air turbine movable between a stowed position and a deployed position is provided including a rotatable hub assembly. A hub face is arranged at a first end of the rotatable hub assembly. The hub face has a non-planar configuration such that a limited portion of a surface area of the hub face is arranged within a plane oriented perpendicular to a direction of travel of an airflow upstream from the hub face when the ram air turbine is in a deployed position.
