GFS-UAV N-02 ‘UFO’ Takes to the Sky

GFS-UAV N-01AAt first glance this flying craft looks like a simple ducted fan with a weird skirt under it. Fancy hovercraft? Kind of. In reality the skirt has no air flowing through it only over it. Something called the ‘Coanda effect‘(wiki) causes the air to ‘stick’ to the outside of the craft and in effect creates an inside out hovercraft. The high efficiency electric motor in the top housing forces air to flow over the outside of the main body to create lift. The torque of the motor and the spin created by the prop wash are countered by the fins that ring the mid section and the direction is controlled by the four lower flaps. The platform is quite stable and looks to be a very good platform for just about any UAV application.
