阅读说明：本技术 螺旋桨、动力组件及飞行器 (Screw, power component and aircraft ) 是由 林家靖 陈鹏 于 2018-09-18 设计创作，主要内容包括：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。(A propeller (100) wherein the angle of attack of the blades (20) is 18.62 ° ± 2.5 ° at a distance from the centre of the hub (10) of 44.0% of the radius of the propeller (100); the angle of attack of the blades (20) is 17.58 ° ± 2.5 ° at a distance from the centre of the hub (10) of 52.0% of the radius of the propeller (100); the angle of attack of the blades (20) is 15.05 ° ± 2.5 ° at a distance from the centre of the hub (10) of 68.0% of the radius of the propeller (100); the angle of attack of the blades (20) is 13.54 ° ± 2.5 ° at a distance from the centre of the hub (10) of 76.0% of the radius of the propeller (100); still relate to a power component and an aircraft. The propeller (100) with the gradually changed wing profiles of the blades (20) is adopted, so that the propeller (100) is located at the optimal working section along each section of the span direction of the blades, the noise generated by the blades (20) during working is reduced, the aircraft (1000) is quieter during hovering, the user experience is improved, meanwhile, the air resistance is also reduced, the pulling force and the efficiency are improved, and the cruising distance of the aircraft (1000) is increased so as to improve the flight performance of the aircraft (1000).)
