One of the most striking features of the AP-3 drone is its double fuselage. We have a patented concept in which we control the aircraft on the tether much like a conventional aircraft using control surfaces. The tether is attached midwing, close to the center of mass. The double fuselage provides the necessary clearance for the tether during maneuvers, such as the climb and the landing. An added benefit is that we can divide the propulsion needed for climb after launch over two fuselages. Both propellers are needed for tethered climb, but with a single propeller we can return to base in any condition. Even if the tether would break or disconnect for some reason. The propulsion runs on batteries. They are sized for a single climb and to assist an emergency landing. It is not active during power generation or during nominal (tethered) landing.
