“…The SH coating was exposed to icing/deicing cycling (IWT), rain erosion, and accelerated aging test, and the results were compared with those from tests performed on SH TiO 2 /stearic acid and commercial hydrophobic fluoropolymer. The IWT test conditions were T = −10 • C with air speed of 43 m/s and LWC of 0.5 g/m 3 . At the end of the study, it was possible to affirm that the prepared SH coating was resistant to UV exposure, and could resist up to 6000 water droplets impact at 165 m/s and especially started to degrade after 170 icing/deicing cycles resulting in the coating with the best performance.…”

“…The authors found no direct correlation between the CA and the endurance time and even when a positive result was observed, it was possible that the surface affected the fluid flow off establishing possible negative effects on aerodynamics. A later study setting out to explore this problem is more accurately described in [3]. In this paper, as opposed to [2], the authors provided detailed information about commercial anti-ice fluids (density, viscosity and surface tension) and employed surfaces (Sa, advancing and receding CA).…”

“…According to a recent examination carried out by scientists from Canada, there is a possibility that the application of anti-icing fluid alongside hydrophobic coatings may hinder the formation of a protective film. Researchers at Skoltech [3] also conducted experiments to assess the ability of aluminum surfaces used in aircraft skins to repel water and ascertain whether this has any impact on the effectiveness of these fluids.…”

The risk of accidents caused by ice adhesion on critical aircraft surfaces is a significant concern. To combat this, active ice protection systems (AIPS) are installed on aircraft, which, while effective, also increase fuel consumption and add complexity to the aircraft systems. Replacing AIPS with Passive Ice Protection Systems (PIPS) or reducing the energy consumption of AIPS could significantly decrease aircraft fuel consumption. Superhydrophobic (SH) coatings have been developed to reduce water adherence to surfaces and have the potential to reduce ice adhesion, commonly referred to as icephobic coatings. The question remains whether such coatings could reduce the cost associated with AIPS and provide durability and performance through suitable tests. In this paper, we then review current knowledge of superhydrophobic and icephobic coatings as potential passive solutions to be utilized alternatively in combination with active systems. We can identify physical parameters, coating composition, structure, roughness, and morphology, durability as properties not to be neglected in the design and development of reliable protection systems in aircraft maintenance.

“…Chemical fluid, mechanical, thermal, hybrid, and other ice protection methods are widely used in commercial aircraft. The chemical fluid ice protection method removes ice deposits and forms a protective film on airplane surfaces (Grishaev et al, 2021). This method protects aircraft surfaces from icing by lowering the freezing temperature of supercooled water below the ambient temperature by mixing a chemical fluid with supercooled water that has been impinged.…”

Aircraft icing remains a key aviation hazard as the global fleet of aircraft in various sectors continues to expand, posing a serious threat to flight safety. As previously stated, the growth of this type of aircraft has been accompanied by an increase in noise levels, and aircraft is reportedly the second most bothersome noise source after traffic. However, integrating an acoustic liner with anti-icing techniques on the leading edge of a nacelle would not efficiently eliminate forward radiated noise and improve the thermal performance of the anti-icing system. Hence, it is of the utmost importance to research the integration of ice protection and noise abatement systems for aircraft applications. This review discusses the integration of ice accretion and noise abatement systems in aircraft applications. The prominence of this review is to explain significant features such as ice protection systems, Computational Fluid Dynamics in ice protection, noise abatement systems, and the integration of ice protection systems and noise abatement systems wherever they are described.

“…These can be classified into three main groups, namely, anti-icing (to avoid the formation of ice by applying surface engineering methods), de-icing (to remove ice once it is accreted on a surface), and combined anti-icing and de-icing. De-icing relies on various physical principles, including the application of low-temperature freezing liquids, [1] the use of the Joule effect, [2,3] solar actuation and photothermal effects, [4][5][6] the de-icing activation with plasmas, [7] the implementation of plasmonic nanoparticles, [8] the application of bulk or guided ultrasonic sound waves in the kHz range generated by external piezoelectric devices, [9,10] or, as reported very recently, the use of surface acoustic waves (SAWs) with suitable substrates coated with a piezoelectric thin film. [11] In this article, we go a step forward and disclose a series of basic ice-substrate interactions upon activation with bulk acoustic waves (AWs) generated in excited piezoelectric substrates.…”

Icing has become a hot topic both in academia and in the industry given its implications in transport, wind turbines, photovoltaics, and telecommunications. Recently proposed de-icing solutions involving the propagation of acoustic waves (AWs) at suitable substrates may open the path for a sustainable alternative to standard de-icing or anti-icing procedures. Herein, the fundamental interactions are unraveled that contribute to the de-icing and/or hinder the icing on AW-activated substrates. The response toward icing of a reliable model system consisting of a piezoelectric plate activated by extended electrodes is characterized at a laboratory scale and in an icing wind tunnel under realistic conditions. Experiments show that surface modification with anti-icing functionalities provides a synergistic response when activated with AWs. A thoughtful analysis of the resonance frequency dependence on experimental variables such as temperature, ice formation, or wind velocity demonstrates the application of AW devices for real-time monitoring of icing processes.
