摘要: 针对飞行汽车螺旋桨高速旋转过程中雨滴冲击导致的表面侵蚀问题,文章提出了一种 基于百微米级矩形阵列凹槽微结构的螺旋桨防护策略。通过超声波气蚀实验模拟侵蚀环境, 采用失重法记录试样质量变化情况,并引入 Logistic 生长曲线深入探究侵蚀累积失重量与时 间之间的关系,以此研究凹槽微结构对螺旋桨聚氨酯涂层抗侵蚀性能的影响。实验结果表明, 表面凹槽阵列微结构(L/W≈2:1)可显著降低侵蚀质量损失,其累计质量损失为 21.82 mg,约 为光滑试样的 48%。同时,明确了材料侵蚀的名义潜伏期、加速期和衰减期,凹槽微结构可 大幅延长材料侵蚀潜伏期,凹槽试样的名义潜伏期达 16.86 h,约为光滑试样的 2.8 倍,因而 表现出优异的抗侵蚀性能。该研究可为飞行汽车螺旋桨表面的抗侵蚀防护提供理论依据。

Abstract: To address the surface erosion problem caused by raindrop impact during the high-speed rotation of flight vehicle propellers, this paper proposes a propeller protection strategy based on the microstructure of rectangular array grooves at the hundred-micron level. By simulating the erosion environment through ultrasonic cavitation experiments, the mass change of the samples is recorded using the weight loss method, and the Logistic growth curve is introduced to deeply explore the relationship between the cumulative weight loss due to erosion and time. This study explores the influence of the groove microstructure on the erosion resistance of the polyurethane coating of the propeller. The experimental results show that the designed groove microstructure (width to spacing ratio of 2) can significantly reduce mass loss, with the cumulative mass loss of the groove sample being 21.82 mg, approximately 48% of that of the smooth sample. At the same time, the nominal incubation period, acceleration period, and attenuation period of material erosion are clarified. The groove microstructure can significantly extend the incubation period of material erosion, with the nominal incubation period of the groove sample reaching 16.86 h, approximately 2.8 times that of the smooth sample, thus demonstrating excellent erosion resistance. This research can provide a theoretical basis for the anti-erosion protection of the surface of flight vehicle propellers.
