小型涵道式无人机的研究进展

Recent researches on small ducted fan UAV

结合涵道式无人机发展现状阐述涵道式无人机的优点,对无人机飞行机理进行分析,结合动力学分析建立涵道式飞行器的数学模型,设计控制器并进行了飞行试验.结果表明:涵道风扇布局飞行器具有较好的悬停性能,在悬停和小角度机动时,各通道之间的耦合可以忽略不计.

The merit of ducted fan UAV is addressed through the illustration of recent researches on it.The flight mechanism of ducted fan vehicles is probed,then a mathematical model of the vehicle is constructed based on the analysis of aerodynamic characters for all the components of the vehicle.The controller is designed and implemented in the flight testing.The results show that the ducted fan UAV has good character of hovering,and there is little cross-coupling between the roll and pitch channels in hovering and maneuvering at a small pitch angle,which can be ignored.
