Abstract

一种螺旋桨(100)，其中，在距离桨毂(10)的中心为螺旋桨(100)的半径的44.0％处，桨叶(20)的攻角为18.62°±2.5°；在距离桨毂(10)的中心为螺旋桨(100)的半径的52.0％处，桨叶(20)的攻角为17.58°±2.5°；在距离桨毂(10)的中心为螺旋桨(100)的半径的68.0％处，桨叶(20)的攻角为15.05°±2.5°；在距离桨毂(10)的中心为螺旋桨(100)的半径的76.0％处，桨叶(20)的攻角为13.54°±2.5°；还涉及一种动力组件及一种飞行器。采用桨叶(20)翼型渐变的螺旋桨(100)能使得螺旋桨(100)在沿着桨叶的展向的每一段都处于最佳工作段，减少了桨叶(20)在工作时产生的噪声，使得飞行器(1000)在悬停时更安静，提高了用户体验，同时，还减少了空气阻力，提高拉力和效率，增加飞行器(1000)的续航距离以提高飞行器(1000)的飞行性能。
