Abstract
Automated launch and retrieval of a “tail-sitting” VTOL aircraft is accomplished by exploiting the natural stability of hover when restrained in tension by an upwind wing tip. For retrieval, a flexible rod is lifted into contact with the trailing edge of the upwind wing as the aircraft translates downwind overhead. Sliding between the rod and wing leads to interlocking of hooks at the rod end and wing tip, while the aircraft swings into a stable tethered hover downwind of the rod. The rod is then used to pull the aircraft upwind into a fixture for secure parking and servicing. After servicing, the aircraft lifts-off into tethered hover, and power margin for climb is assessed. If the aircraft is judged to have sufficient power safely to proceed, then the interlocking hooks are disengaged, leaving the aircraft to climb away in free flight.
