Abstract

This work presents further controller development and flight testing work towards the validation of a VTOL freewing UAS concept and dynamic model. Previous work has focused on hover controller design and performance culminating in a flight consisting of a manually piloted vertical take-off, hover, and vertical landing. A new testbed vehicle is constructed based on the lessons learned from this previous work that is suitable for manual and autonomous flight in transition. An adaptive autopilot is designed in the transition and forward flight regions in a flight-capable software environment. This autopilot is finally implemented on flight control hardware on the testbed vehicle. Manually piloted flight tests are conducted in which the vehicle takes off vertically, transitions to a nearly forward flight configuration, and returns back to vertical flight mode for landing. Next steps include validating the autonomous vertical take-off, hover, transition to forward flight, and vertical landing performance with the integrated adaptive autopilot.
