Invisible Drones

"Persistence of Vision" -- the same effect that makes helicopter rotor blades nearly invisible when rotating at high speed -- allows this VeraTech Aero drone prototype to fly nearly invisibly. Pretty cool.

The ability of U.S. ground troops to safely navigate the gauntlet of the urban battlefield has been greatly enhanced through the development of the VeraTech Aero "Phantom Sentinel" line of Virtually Invisible VTOL UAV Surveillance platforms. The Phantom Series single blade rotorcraft has the ability to deliver close up, real time video intelligence within 75 feet of nearly any event and remain virtually undetectable to the human eye.

Based on the concept of persistence of vision, the Phantom's single rotor blade has a center of rotation outside of the UAVs' physical fuselage. As the aircraft spins, it disappears from vision. The Phantom has a uniquely minimal cross section allowing it to "slice" through even the most adverse weather conditions that would keep conventional UAV systems on the ground. The rotational inertia generated in flight allows the UAV to self level and maintain a very high degree of stability, even while hovering. Phantom is scalable from two to ten feet in length to accommodate a wide variety of flight times and payloads. The compact size and light weight make it easy to fold, field pack, and hand launch.
