An Annular Wing VTOL UAV: Flight Dynamics and Control

Blog Article

A vertical takeoff and landing, unmanned aerial vehicle is presented that features a quadrotor design for propulsion and attitude stabilization, and an annular wing that provides lift in forward flight.The annular wing enhances human safety by borstlist självhäftande enshrouding the propeller blades.Both the annular wing and the propulsion units are fully characterized in forward flight via wind tunnel experiments.An autonomous control system is synthesized that is based on model inversion, and accounts for the aerodynamics of the wing.

It also accounts for the dominant aerodynamics of the propellers in forward flight, specifically the thrust and rotor torques when subject to oblique flow conditions.The attitude controller employed is tilt-prioritized, as the aerodynamics are invariant to the twist angle of the vehicle.Outdoor experiments are performed, resulting in accurate cga 200 to cga 510 adapter tracking of the reference position trajectories at high speeds.
