Wind Tunnel Experimental Study on Hybrid Ice Protection Systems for Composite Materials

Aircraft icing poses a significant threat to flight safety, making anti-icing technology a key focus in aerospace research. This paper investigates a novel hybrid anti-icing technology that combines electro-thermal and super hydrophobic coatings. Through experiments conducted in icing wind tunnel, the effectiveness of various anti-icing strategies was evaluated. The experimental results indicate that the electro-thermal and super hydrophobic coupled model not only effectively prevents ice formation but also reduces energy consumption. Furthermore, this system demonstrated no occurrence of runoff ice, exhibiting excellent anti-icing performance and economic viability. This study lays the groundwork for the future integration of piezoelectric excitation in anti-icing technology development.
