Multiphysics anti-icing simulation of a CFRP composite wing structure embedded with thin etched-foil electrothermal heating films in glaze ice conditions

A Review of Icing Research and Development of Icing Mitigation Techniques for Fixed-Wing UAVs

“…Roy et al [118] designed and developed an integrated electrothermal anti-icing system using a thin etched foil heating film. The system was integrated into the leading edge of a CFRP laminate wing of a UAV.…”

Electrical resistance-based monitoring of CFRP thickness during vacuum assisted resin infusion

“…Owing to their superior specific strength modulus, carbon fiber-reinforced plastics (CFRPs), particularly thermoset CFRPs, have attracted attention in various fields, such as civil infrastructures [1][2][3], vehicles [4,5], railways [6], and airplanes [7,8]. However, manufacturing CFRPs requires intricate consumption conditions, such as time, cost, and labor.…”

A sandwich-structured intelligent anti-icing/de-icing film with ice-oriented power self-regulating performance

“…1 Among these techniques, traditional thermal anti-icing techniques have been the most widely applied due to their reliability and direct response, yet have fallen short of the allweather flight requirements for UAVs with insufficient energy 2 and aircrafts with large proportion of low-thermal-conductivity composite materials. 3,4 Based on this situation, bio-inspired passive anti-icing surfaces have sprung up to fill the vacancy of anti-icing techniques without energy consumption, including superhydrophobic surfaces from lotus leaves, [5][6][7][8][9][10] slippery liquid-infused porous surfaces (SLIPS) from Nepenthes, [11][12][13][14] coatings with aqueous lubricating layers or polymer brushes, [15][16][17] low-interfacial toughness materials, 18 etc. The underlying logic of these bio-inspired anti-icing techniques is utilizing the low interface adhesion to promote ice removal via gravity, wind flow or vibration and can really work under certain circumstances like static icing conditions of air conditioners, refrigerators or natural outdoor environments.…”

“…21,24 Owing to the very large area and complex shape of protected surfaces on aircraft wings, wind turbine blades and high-speed train chassis, the distribution of accreted ice on these fastmoving surfaces is generally uneven and influenced by various flow fields. 3,[25][26][27][28] Developed active anti-icing and de-icing techniques are generally not self-adaptive to uneven and variable ice accretion, leading to mismatching of energy output and ice distribution and thus the waste of energy. On large aircraft wings, electric heating elements are usually segmented into several, even tens of zones, 29 which are individually detected by temperature sensors and controlled to allocate the power output.…”
