Scientists create variable vectoring technique for propeller-powered unmanned aerial vehicles

The unmanned aerial vehicles (UAV) designed for plateau missions are usually installed with high span chord ratio wings, which provide more lifting force at a relatively low airspeed. Such UAVs, however, tend to lose their maneuverability. Hence, they usually need a larger turning radius and are unable to maintain altitude during sharp slope turning, as the lifting force produced by the wings decreases dramatically when the bank angle is large. This may pose a risk to flight safety in plateau mo
