The icing of propellers is a critical factor that affects the safe operation of aircraft. A superhydrophobic surface, with its extremely low wettability, is highly valuable in the field of anti-icing. This study investigates the distribution pattern of ice on propeller surfaces by employing spray coating to create superhydrophobic surfaces. Additionally, it conducts a comparative analysis of thrust and power under icing and non-icing conditions to comprehensively assess the impact of superhydrophobic surfaces on propeller operation efficiency. The results show that superhydrophobic surfaces not only diminish the ice formation area on propeller surfaces but also enhance the traction of propellers under icing conditions, reducing the power consumption of the propeller. The generated thrust can reach up to 1.6 times that of non-superhydrophobic propellers while consuming only one-third of the power. Furthermore, under non-icing conditions, superhydrophobic surfaces exhibit minimal impact on propeller performance.

超疏水螺旋桨防冰性能和运行效率综合评价


螺旋桨结冰是影响飞机安全运行的关键因素。超疏水表面具有极低的润湿性，在防冰领域具有很高的价值。本研究通过采用喷涂形成超疏水表面来研究冰在螺旋桨表面的分布模式。此外，还对结冰和非结冰条件下的推力和功率进行对比分析，全面评估超疏水表面对螺旋桨运行效率的影响。结果表明，超疏水表面不仅减少了螺旋桨表面的结冰面积，而且在结冰条件下增强了螺旋桨的牵引力，降低了螺旋桨的功耗。产生的推力可达非超疏水螺旋桨的1.6倍，而功耗仅为非超疏水螺旋桨的三分之一。此外，在非结冰条件下，超疏水表面对螺旋桨性能的影响最小。
