Reduction of tilt rotor download using circulation control [PDF]
The effect of boundary layer control blowing on the download of a wing in the wake of a hovering rotor was measured in a small scale experiment. The objective was to evaluate the potential of boundary layer control blowing for reducing tilt rotor ...

Suspended Load Path Tracking Control Using a Tilt-rotor UAV Based on Zonotopic State Estimation
, 2018 This work addresses the problem of path tracking control of a suspended load using a tilt-rotor UAV. The main challenge in controlling this kind of system arises from the dynamic behavior imposed by the load, which is usually coupled to the UAV by means ...
