摘要

针对翼型动态磨损与气动特性变化这一问题,通过射流喷砂平台模拟翼型的沙尘侵蚀,并采用粒子图像测速（PIV）技术和应变天平,对比分析磨损前后翼型周围流场及升阻力的变化规律。实验结果表明,当翼型的冲蚀磨损率超过0.205%时,线性区内的翼型升力系数降低了约0.2,但失速迎角较未磨损翼型有所增加。同时冲蚀磨损导致翼型阻力系数最多可降低约0.025,表明冲蚀磨损在一定程度上推迟了翼型的气流分离,从而改善了翼型的失速特性。

Abstract

To address the issue of dynamic wear and the associated aerodynamic property changes of the airfoil, this study uses a jet sandblasting platform to simulate sand and dust erosion on the airfoil. Additionally, particle image velocimetry （PIV） and strain balance techniques are employed to compare changes in the flow field around the airfoil and its lift and drag coefficients before and after wear. The experimental results show that when the erosion wear rate of the airfoil exceeds 0.205%, the linear region of the lift coefficient decreases by approximately 0.2, while the stall angle increases compared to that of the unworn airfoil. At the same time, erosive wear results in a reduction of the drag coefficient by approximately 0.025. Notably, the erosive wear delays the onset of airflow separation, which improves the stall characteristics of the airfoil.
