摘　　要：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.本文研究了螺旋桨运输机在沙漠、高原等恶劣环境中飞行时,螺旋桨与沙尘颗粒碰撞和摩擦引起的表面冲蚀磨损.首先,使用商业软件FLUENT分析在不同沙尘颗粒参数下单个螺旋桨叶片的冲蚀行为.随后,通过滑移网格法对整个叶片进行动态模拟,研究在不同工况条件下(包括转速和爬升角度)的冲蚀机理.最后,根据模拟结果,得出冲蚀对螺旋桨气动特性的影响.该研究深入探讨了大型飞机螺旋桨在沙尘环境中运行时的冲蚀规律以及螺旋桨表面冲蚀磨损对气动性能的影响.通过阐明这些现象,本研究为未来优化螺旋桨设计提供了宝贵的意见.
