Abstract

This study introduces wing-shaped composite airfoils integrated with high-efficiency, multifunctional anti-icing heating elements composed of nickel-plated carbon fiber. The anti-icing performance of these airfoils was evaluated through experiments conducted in an Icing Research Tunnel (IRT) under representative glaze icing conditions. These results indicate that the nickel-plated carbon fiber exhibits an electrothermal conversion efficiency of 0.1 W/℃ and a heating rate of 0.64 ℃/s. In particular, icing wind tunnel tests conducted at a power density of 9.0 kW/m² demonstrated that the heating zone remained above the freezing point, thereby preventing ice accretion, while runback ice formed in the region c orresponding to X/C ≈ 24–32 % during a 300 s accretion period. The experimental results demonstrated high reliability and accuracy, showing a temperature difference of <0.5 °C compared to the surface temperature predicted by the multiphysics anti-icing simulation under identical conditions.

翼型复合材料翼型多功能高效防冰镀镍碳纤维加热元件的数值与实验研究

本研究介绍了一种翼型复合材料翼型，该翼型集成了由镀镍碳纤维组成的高效多功能防冰加热元件。在结冰研究隧道（IRT）进行了具有代表性的釉面结冰条件下的机翼型抗结冰性能试验。结果表明，镀镍碳纤维的电热转换效率为0.1 W/℃，升温速率为0.64℃/s。特别是，在9.0 kW/m²功率密度下进行的结冰风洞试验表明，加热区保持在冰点以上，从而防止了冰的增加，而在300 s的增加期内，对应于X/ c≈24 - 32%的区域c形成了回冰。实验结果显示了较高的可靠性和准确性，在相同条件下，与多物理场防冰模拟预测的表面温度相比，温度差异为0.5°C。
