Abstract

This study examines the erosion and wear behavior of coaxial contra-rotating propeller (CRP) blades operating in extreme wind-sand environments, such as desert plateaus, and evaluates the subsequent effects of airborne sand and dust particles on the blades' aerodynamic performance. First, the configured CRP is compared with open-rotor wind-tunnel datasets (NASA ORPR and AI-PX7/S1MA) under clean-surface conditions (no particle erosion) to verify the accuracy and reliability of the simulation settings. Then, the influence of key operational parameters is investigated, including rotational speed and blade spacing, on the erosion and wear characteristics of the propeller blades. Through a detailed analysis of wear patterns on the blade surface under varying operational conditions, the relationship between these parameters and the extent of blade degradation is elucidated. Next, the regions on the blade surface are identified and classified with varying degrees of erosion. The effects of surface roughness in these damaged regions on the aerodynamic performance of the CRP are thoroughly explored. Particular attention is given to the impact of different levels of surface roughness on aerodynamic efficiency, thrust, and power consumption, with a focus on influence of different roughness on propeller performance. The findings provide theoretical insights that contribute to the design and optimization of propeller blades for operation in harsh wind-sand environments, enhancing both blade durability and aerodynamic efficiency.

同轴对旋螺旋桨冲蚀磨损及气动特性数值研究

本研究考察了同轴对旋螺旋桨（CRP）叶片在极端风沙环境（如沙漠高原）下的侵蚀和磨损行为，并评估了空气中沙尘颗粒对叶片气动性能的后续影响。首先，将配置好的CRP与表面清洁（无颗粒侵蚀）条件下的开式风洞数据集（NASA ORPR和AI-PX7/S1MA）进行比较，验证模拟设置的准确性和可靠性。然后，研究了转速和叶片间距等关键工作参数对螺旋桨叶片冲蚀磨损特性的影响。通过对不同工况下叶片表面磨损形态的详细分析，阐明了这些参数与叶片退化程度的关系。接下来，根据不同的侵蚀程度对叶片表面的区域进行识别和分类。深入探讨了这些损伤区域的表面粗糙度对CRP气动性能的影响。特别关注不同水平的表面粗糙度对气动效率、推力和功耗的影响，重点关注不同粗糙度对螺旋桨性能的影响。该研究结果为在恶劣风沙环境下运行的螺旋桨叶片的设计和优化提供了理论见解，提高了叶片的耐用性和气动效率。

期刊介绍： Wear journal is dedicated to the advancement of basic and applied knowledge concerning the nature of wear of materials. Broadly, topics of interest range from development of fundamental understanding of the mechanisms of wear to innovative solutions to practical engineering problems. Authors of experimental studies are expected to comment on the repeatability of the data, and whenever possible, conduct multiple measurements under similar testing conditions. Further, Wear embraces the highest standards of professional ethics, and the detection of matching content, either in written or graphical form, from other publications by the current authors or by others, may result in rejection.
