AI中文摘要：
传统多旋翼飞行器在悬停时会主动抑制偏航旋转，尽管力平衡或高度控制并不需要偏航调节，仍会消耗功率来保持固定航向。本文挑战这一范式，提出一种自旋四旋翼架构，其故意以持续偏航率运行，将原本用于偏航调节的功率转化为有用的空气动力学效应。本文建立了自旋四旋翼的动力学模型，对低雷诺数（Re）范围进行分析以选择升力面的翼型。初步硬件测试显示所需推力降低了22%。这些结果表明，故意的偏航旋转不应被抑制，而可作为高效且鲁棒的多旋翼飞行设计机制加以利用。
英文摘要：
Conventional multirotor aerial vehicles actively suppress yaw rotation during hover, expending power to maintain a fixed heading despite the fact that yaw regulation is not required for force balance or altitude control. This paper challenges that paradigm by proposing a spinning quadrotor architecture that intentionally operates at a sustained yaw rate, converting power traditionally spent on yaw regulation into useful aerodynamic effects. A dynamic model of the spinning quadrotor is developed, analysis for low Re range is conducted to choose an airfoil for lifting surfaces. Preliminary hardware tests show a 22% reduction in thrust required. These findings suggest that intentional yaw rotation, rather than being suppressed, can be exploited as a design mechanism for efficient and robust multirotor flight.
