“…This can also be predicted by the de-icing capability prediction method considering the impact of the impedance matching device by using simulation results and measurement data. Finally, when considering the power consumption level in the de-icing experiment, the maximum power consumption per unit area in all modal de-icing experiments is 0.167 W/cm 2 , which is smaller than the de-icing energy consumption (0.95 W/cm 2 ) of the electric heating system described in the literature [4].…”

“…The icing of aircraft and wind turbines causes component damage, results in operation disruption, and inherent equipment loss, as well as their potential for causing serious accidents [1,2]. Different types of anti/de-icing methods, such as thermal [3], mechanical [4], chemical [5] and other methods with new principles guide (for example, plasma [6]) have been introduced by researchers to deal with the ice threat. With high reliability and efficiency, ice-protection systems are commonly used on aviation equipment with thermology methods [3].…”

Due to the safety threats caused by icing, the de-icing system is essential in the aviation industry. As an effective method, the electromechanical de-icing system (EDS) is a new ice-protection system based on mechanical vibration principles. For the majority of the current research on system de-icing capability estimation, the effect of impedance-matching is not considered. Impedance matching plays a very important role in improving the performance of the electromechanical system, so we must also consider the impact of impedance matching when designing the EDS. In the present study, a de-icing capability prediction method considering the impact of an impedance-matching device is established based on experimental and numerical methods. The results indicate that the impedance-matching effect has no impact on the mechanical vibration of the structure for the same load power. Meanwhile, impedance-matching devices can significantly improve the power factor and increase the interface shear stress/strain for de-icing. Eight different vibrational modes were tested, and the experimental results showed that the actual interface shear strain after impedance matching is inversely proportional to the de-icing time. The verification experiments were conducted and the accuracy of the proposed prediction method was verified.

“…As aircraft are traveling through frozen clouds, ice can form on the surface of the windward components due to the impact of supercooled water droplets [1], and the probability of aircraft icing during flight is as high as 92% [2]. This can severely damage aerodynamic performance, affect maneuvering stability, and interfere with instrumentation equipment, which can result in serious harm to aircraft flight safety [3].…”

Ice accumulation on aircraft can lead to aerodynamic performance degradation and even trigger security incidents. However, traditional SDBD reactors can't work while covered by glaze ice. In the present work, a novel three-electrode double-sided SDBD is proposed and employed for glaze ice deicing. Compared with traditional SDBD reactor, three-electrode double-sided SDBD introduces an additional discharge area and grounding electrode. On one hand, the heat generated in the additional discharge area can melt the glaze ice covered on the high-voltage electrode, providing a discharge gap for the subsequent discharge. On the other hand, the introduction of the additional grounding electrode can also dramatically enhance the upper discharge and thermal effect. As a result, compared with the three-electrode single-sided SDBD and two-electrode double-sided SDBD, the three-electrode double-sided SDBD has the highest deposited energy, maximal temperature, and deicing rate. To further optimize the structural design, the effect of air gap length below the dielectric on three-electrode double-sided SDBD is investigated. And it is found that the best deicing performance can be obtained at the air gap length of 1 mm.
