The Cyber Quad is an electric ducted quadrotor Vertical Take Off and Landing (VTOL) Unmanned Aerial Vehicle (UAV).
Cyber Quad is a unique amalgamation of state-of-the-art VTOL UAV technologies, combining the mechanical simplicity, low noise, stability and agility of a quadrotor, with the compactness, safety and efficiency of ducted fans.
With only four moving parts that are safely shrouded, the Cyber Quad is low maintenance, easily transportable and rapidly deployable.

The Cyber Quad employs direct drive brushless electric motors, avoiding the inefficiencies, maintenance and noise of gearboxes and internal combustion engines. By running relatively low speed rotors with the tips aero-dynamically entrained by the duct wall, BVI noise and tip losses are significantly reduced. These features contribute to the Cyber Quad having a very low noise signature for stealth applications.
Cyber Quad does not employ any complicated, inefficient control surfaces, swash plates, stabilizer bars, or tail rotors for control. In fact, it does not pay any additional weight or power penalty for control as it simply differentially controls the four modular fans that are already being employed to create lift. Furthermore, it has counter rotating pairs of fans so that all gyroscopic dynamics and dissymmetry of lift issues are eliminated.
Cyber Quad employs state-of-the-art inertial sensors and high frequency speed controllers to actively stabilise its attitude and heading. This allows both robust disturbances rejection in hover and high maneuverability if needed.
The Cyber Quad ducted fans are optimised for high static thrust efficiency (hover endurance); producing 33% more lift than a helicopter with the same power and rotor area. This equates to a much smaller footprint for the same payload/endurance capability. With this compact footprint and no exposed rotors, Cyber Quad can safely operate near people and through urban environments. Cyber Quad|Unmanned Aerial Vehicle|Quadrotor|UAV
