Abstract: Crossflow axes rotary mechanical devices with dynamic increased swept area including at least two rotors attached to a support structure having their axes of rotation parallel to each other, having at least one blade attached to each rotor via a joint where the swept areas created by the blades of each rotor intersect, having at least one rotor synchronizing component so the blades from each rotor do not collide during the rotation are described. The rotors with blades share the space, the support structure, the rotor synchronizing component, the electric machines, as well as the characteristics, parameters, and effects that the crossflow axes rotary mechanical devices with dynamic increased swept area have compare to the crossflow axes rotary mechanical devices without dynamic increased swept area.

Abstract: Crossflow axes rotary mechanical devices with Dynamic Increased Swept Area including at least two rotors with equal arm sizes attached to a support structure parallel to each other, having their axes of rotation perpendicular to the fluid with a rotors offset 0<=Ro<2R, rotating relative to each other in synchrony by a rotors synchronizing mechanism, having at least one blade attached to each rotor via the radial arm where the blades of the opposite rotors do not collide during the rotation, are described. The rotors with arms and blades share their spaces, the fluid, the support structure, the rotors synchronizing mechanisms, the electric machines, the braking systems, the yawing systems, as well as the characteristics, parameters, effects and additional mechanisms that the crossflow axes rotary mechanical devices with Dynamic Increased Swept Area have compare to the crossflow axes rotary mechanical devices without Dynamic Increased Swept Area.
