Abstract

This study aims to characterize solid particle erosion behaviors of three different aluminum alloys (AA2024-T351, AA6061-T651, and AA7075-T651) and reveal their erosion performances on leading-edge slat of airplane wings. Solid particle erosion tests were conducted using silicon carbide erodent particles under the conditions of six different impingement angles (20°-90°) and four different impact velocities (70-192 m/s). The erosion simulations of a leading-edge slat of the aforementioned aluminum alloys were numerically simulated at four different rotation angles (0°-15°) for three different impact velocities (130-250 m/s). A commercial ANSYS Fluent software using the Euler-Lagrange equation and an experimental data-based erosion model was used for the erosion simulations. The experimental results showed that the erosion rate increases with increasing impact velocity and the maximum erosion rate is obtained at the impingement angle of 30° which reflects the ductile manner. Of the three aluminum alloys, the AA6061-T651 exhibited the worst erosion behavior followed by the AA2024-T351 sample, whereas the AA7075-T651 had the best erosion resistance. The numerical results indicated that the erosion rate values of slat surfaces made up of three different aluminum alloys showed a slight increase after a slat rotation angle of 5°.

前缘板条铝合金材料的固体颗粒侵蚀性能研究

本研究旨在表征三种不同铝合金（AA2024-T351、AA6061-T651 和 AA7075-T651）的固体颗粒侵蚀行为，并揭示它们在飞机机翼前缘板条上的侵蚀性能。在六种不同的撞击角（20°-90°）和四种不同的撞击速度（70-192 m/s）条件下，使用碳化硅侵蚀颗粒进行了固体颗粒侵蚀试验。在四种不同的旋转角度（0°-15°）和三种不同的冲击速度（130-250 m/s）下，对上述铝合金前缘板条的侵蚀模拟进行了数值模拟。侵蚀模拟使用了商用 ANSYS Fluent 软件，该软件使用欧拉-拉格朗日方程和基于实验数据的侵蚀模型。实验结果表明，侵蚀率随冲击速度的增加而增加，在冲击角为 30°时侵蚀率最大，这反映了韧性方式。在三种铝合金中，AA6061-T651 的侵蚀表现最差，其次是 AA2024-T351 样品，而 AA7075-T651 的抗侵蚀性最好。数值结果表明，在板条旋转角度为 5° 时，三种不同铝合金板条表面的侵蚀率值略有增加。
