Cyclorotor aerodynamics for advanced aerial mobility

旋翼机是一种旋转翼系统，由一组围绕平行于其前缘的水平轴旋转的俯仰叶片组成。这提供了高水平的机动性，非常适合需要持续悬停和推力矢量能力的应用。旋翼飞行器目前正在不同规模上进行测试——从纳米和微型飞行器到更大规模的飞机，以空中出租车的形式满足人们对城市空中交通部门日益增长的兴趣。到目前为止，由于相对较少的优化，旋翼机在小范围内的性能已经与传统螺旋桨相当或更好。然而，我们对流体物理知之甚少，我们需要进一步优化它们的性能。

A cyclorotor is a rotating-wing system, consisting of a set of pitching blades that rotate about a horizontal axis parallel to their leading edge. This offers a high level of manoeuvrability and is extremely suitable for applications that require sustained hovering and thrust-vectoring capabilities. Cyclorotors are currently being tested on different scales - from nano and micro air vehicles to larger scale aircraft that caters to the rising interest in the Urban Air Mobility sector in the form of air-taxis. With relatively little optimisation so far, cyclorotors already perform on par or better than traditional propellers at small scales. However, we have very little understanding of the flow physics, and we need this to further optimise their performance.
