Abstract

This study investigates surface erosion wear caused by collision and friction between propellers and sand particles during the flight of propeller transport aircraft in harsh environments like deserts and plateaus, which are characterized by strong sand and wind conditions. Firstly, the erosion behavior of individual propeller blades is analyzed under various sand particle parameters using the commercial software FLUENT. Subsequently, dynamic simulations of the entire blade are conducted by the sliding mesh method to examine erosion patterns under different operational conditions, including rotation speed and climb angle. Finally, the impact of erosion on the aerodynamic characteristics of the propeller is obtained based on simulation results. This study delves into the erosion patterns observed in large aircraft propellers operating within sandy and dusty environments, as well as the consequential impact of propeller surface wear on aerodynamic performance. By elucidating these phenomena, this research provides valuable insights that can inform future endeavors aimed at optimizing propeller design.

飞机螺旋桨侵蚀磨损和空气动力特性

本研究探讨了螺旋桨运输机在沙漠和高原等风沙较大的恶劣环境中飞行时，螺旋桨与沙粒碰撞和摩擦造成的表面侵蚀磨损。首先，使用商业软件 FLUENT 分析了不同沙粒参数下单个螺旋桨叶片的侵蚀行为。随后，采用滑动网格法对整个叶片进行动态模拟，研究不同运行条件（包括转速和爬升角）下的侵蚀模式。最后，根据模拟结果得出侵蚀对螺旋桨气动特性的影响。本研究深入探讨了在沙尘环境中运行的大型飞机螺旋桨的侵蚀模式，以及螺旋桨表面磨损对空气动力性能的影响。通过阐明这些现象，本研究提供了宝贵的见解，可为今后旨在优化螺旋桨设计的工作提供参考。
