Abstract

The article presents the analysis of pitching moment in a drone propeller. This aspect of blade design process is not frequently considered, as variable pitch propellers (VPPs) aren’t usually implemented in small-size aerial vehicles due to their mass and reliability issues. The research shows a potential for addressing these issues for both active- and passive VPP systems by pivot point displacement. Discussed herein are the principles of the developed BEM-based optimisation tool for the blade analysis, confronted with an in-house experiment. The analysis then follows towards practical implications of the obtained results. The article contributes to the general design know-how of drone propellers and shows a potential for wider implementation of the VPP technologies for the miniature-scale propellers.

增强无人机螺旋桨：基于bem的俯仰优化的实际见解

本文对无人机螺旋桨的俯仰力矩进行了分析。由于变螺距螺旋桨（vpp）的质量和可靠性问题，通常不会在小型飞行器上实施，因此叶片设计过程的这一方面并不经常被考虑在内。该研究表明，通过枢轴点位移来解决主动和被动VPP系统的这些问题是有潜力的。本文讨论了开发的基于bem的叶片分析优化工具的原理，并进行了内部实验。接着分析所得结果的实际意义。本文有助于无人机螺旋桨的一般设计知识，并显示了微型螺旋桨VPP技术更广泛实施的潜力。
