MetaMorpher is a twin-wing unmanned aerial vehicle capable of both spinning-wing hover and fixed flying-wing cruise. The design aims to bring together the vertical agility of a rotorcraft and the endurance of a fixed-wing aircraft in a single airframe.
The paper describes the vehicle's design and a motor-flap propulsion control strategy. This control approach is presented as the means to manage the vehicle's behavior across the two flight modes, though the abstract leaves the specifics of the transition for the full text.
As described in the arXiv abstract, the work is focused on the design and control of this metamorphic UAV, with the dual-mode capability being the central contribution.
