摘要/Abstract

摘要： 针对旋翼/螺旋桨的大负扭和后掠桨尖设计在桨叶内部所带来的严重应力应变集中问题，结合三维结构动力学模型、旋翼气动模型和旋翼配平方法，对复合材料旋翼/螺旋桨进行了综合建模与气弹载荷分析，并通过悬停实验验证了综合模型的准确性。对比分析了无负扭、大负扭和大负扭带后掠桨尖的桨叶气弹特性，发现大负扭导致桨叶应力集中区域扩大，后掠桨尖使桨尖过渡区域的应力集中区域扩大，集中程度加剧。

Abstract: The issues of significant stress and strain concentration within the prop-rotor blades caused by large negative twist and swept tips were addressed herein. By 3D structural dynamics model, rotor aerodynamics model, and rotor trim methods, a comprehensive model of composite prop-rotor was developed, and the aeroelastic loads of composite prop-rotor were analyzed, and the accuracy of the synthesis model was validated through hover experiments. The analysis of aero-elastic characteristics was performed for rotor blades with zero twist, large negative twist, and large negative twist with swept tips. The results indicate that the large negative twist enlarges the stress concentration area, while the swept tip makes the stress concentration at the swept transition area larger and the degree of concentration worsens.

Key words: , prop-rotor, complicated geometry blade, rotor aero-structural coupling, 3D structural blade model, 3D strain and stress
