1.
This paper introduces current development and trends of ducted fan flying robot which takes advantages of VTOL(Vertical Take-Off and Landing) techniques.
文中介绍了基于涵道风扇技术变姿飞行机器人的发展现状及趋势,还分析了变姿飞行机器人变姿的方式及关键技术。
2.
Compared with the propeller or the rotor,the ducted fan provides a larger aerodynamic thrust(lift) and the low noise due to the shrouding duct.
涵道风扇较同样直径的孤立风扇能产生更大的升力,且风扇环括在涵道内,既可阻挡风扇气动声向外传播,又结构紧凑、安全性高。
3.
Some unmanned aerial vehicles can vertically take off and land with the ducted fan system, but there is no valid method to analyze the aerodynamic characteristics of a ducted fan system currently.
