AirShip VTOL UAV Hover Capability
The aircraft?s three turbine assemblies supporting twin counter rotating ducted fan rotors (two laterals and one rear) provides the configuration to ensure the air/vehicle?s hover stability. The AirShipTG VTOL UAV is able to hover by aerodynamic means. The aircraft?s ducted fan rotors rotate, and as it does so, generates an aerodynamic propulsive lift force. The air/vehicle pulls itself upward to a hover position because of the aerodynamic force acting on its rotors as they slice through and displace air. This image illustrates the AirShipTG VTOL UAV ?pushing against the ground," as it were, and the red streamlines indicate the high-velocity air exhaust exiting through all three ducted fan rotors producing the thrust needed to keep the aircraft airborne and into a hover position.
