Abstract: Various embodiments provide ice mitigating surface coatings and methods for applying ice mitigating surface coatings. Various embodiment ice mitigating surface coatings may be formed by hydrolysis of one or more substituted n-alkyldimethylalkoxysilanes terminated with functionalities having the following characteristics with respect to water: 1) non-polar interactions; 2) hydrogen bonding through donor and acceptor interactions; or 3) hydrogen bonding through acceptor interactions only. The substituted n-alkyldimethylalkoxysilanes of the various embodiments may include methyl terminated species, hydroxyl terminated species, ethylene glycol terminated species, and methoxyethylene glycol terminated species. Various embodiment ice mitigating surface coatings may be applied to metal surfaces, such as aluminum surfaces. Various embodiment substituted n-alkyldimethylalkoxysilanes may have an aliphatic chain that is saturated and liner or branched or that is partially unsaturated and liner or branched.

Abstract: A bond fixture includes a first frame defining a chamber configured to receive a leading edge of a rotor blade and a second frame pivotally coupled to the first frame. The second frame is movable between a first position and a second position. In the second position, the second frame restricts movement of the bond fixture relative to the rotor blade. At least one supporting assembly extends from the first frame towards the chamber. The at least one supporting assembly is adjustable to apply a pressure to an adjacent surface of the rotor blade.

Abstract: The invention relates to a hybrid electric drive system (10) for multi-motor aircraft (20). The hybrid electric drive system comprises at least a first and a second hybrid electric drive unit (31, 32), each of which comprises: an internal combustion engine (41, 42), a motor-generator unit (71, 72) and a gear box (51, 52) for transmitting drive power to a propeller (61, 62). In order to supply the motor-generator units (71, 72) with electrical energy, the drive system (10) has a fuel cell (73), which in turn is supplied with hydrogen by means of a fuel tank (74). In the fuel cell (73), hydrogen is converted into electricity, which then supplies the motor-generator unit (71, 72) with electrical power by means of the transmission device (80) and power converters (81) and (82), in order to drive the propellers (61, 62). Advantages: On the basis of a turboprop aircraft (20) with approximately 40 to 90 passengers, approximately 40% of the energy during a 1-hour mission can be provided emission-free by means of hydrogen and fuel cell. This means no CO2 emissions at all during the cruising flight and also no climate-damaging exhaust-gas and contrail effects at cruising altitude (FL250), which are a significant share of aviation emissions.

Abstract: The articles and methods described herein provide a way to manipulate condensation on a surface by micro/nano-engineering textures on the surface and filling the spaces between the texture features with an impregnating liquid that is stably held therebetween or therewithin. The articles and methods allow droplets of water, or other condensed phases, even in micrometer size range, to easily shed from the surface, thereby enhancing contact between a condensing species and the condensing surface. It has been found that dropwise condensation is enhanced by the use of an impregnating (secondary) liquid that has a relatively high surface tension, and, even more preferably, an impregnating liquid that has both a high surface tension and a low viscosity.

Abstract: The present disclosure describes a strategy to create self-healing, slippery liquid-infused porous surfaces. Roughened (e.g., porous) surfaces can be utilized to lock in place a lubricating fluid, referred to herein as Liquid B to repel a wide range of materials, referred to herein as Object A (Solid A or Liquid A). Slippery liquid-infused porous surfaces outperforms other conventional surfaces in its capability to repel various simple and complex liquids (water, hydrocarbons, crude oil and blood), maintain low-contact-angle hysteresis (

Abstract: A coating includes at least one coating layer containing first particles, second particles, and third particles distributed throughout a cross-linked, continuous polymer matrix. An outer surface of the coating layer includes surfaces of at least first particles extending outward from a top periphery of the polymer matrix. The outer surface exhibits a property of delaying ice formation compared to the coating layer without the first particles. A method includes applying a coating composition in one application step. The one-step coating composition contains first particles, second particles, and third particles in a base containing a polymer. A coating composition includes first particles, second particles, and third particles distributed in a matrix precursor.
