The rotorcraft includes a fuselage with a pair of counter-rotating rotor blade assemblies each having a plurality of radially-extending airfoil shaped blades about a vertically disposed central axis.

This is done by changing the pitch angles of the blades and / or by utilizing respective flaps pivotally mounted to the blades to change the effective pitch angle of the blades.

The MRSS provides rigid non-permeable platform for attaching or incorporating additional safety devices as found in the Drone industry (or other industries) resulting in a safety device that completely prevents the loss a Drone due to the catastrophic failure of any Drone system or combination of systems which would typically result in rapid decent, and / or uncontrolled flight. The MRSS makes Drones safe near humans and safe to use around public gatherings, stadium events, accident scenes, disaster search and rescue and disaster relief, and indoors for the security and communications markets among others expanding the availability of Drones to further assist humanity.

The invention discloses an aircraft generating a larger lift from its interior. The fluid channel inside the aircraft communicates with the engine and the ports on the upper surface of the outer shell. With the powerful suction of the engine, the fluid on the upper surface of the outer shell is quickly sucked into the fluid channel via respective ports under conditions of long path, large area, high speed and low air pressure, which results in large lift from the interior of the aircraft. In the course of generating the lift, the fluid resistances of the fluid wall and the fluid hole are sucked into the fluid channel through the ports at the front and the surrounding area of the aircraft, then high-speed fluid is emitted from the rear port. This approach contributes greatly to the transformation of the existing aircraft. The unified big wing significantly improves the lift, the speed and the carrying capacity of the existing aircraft with lowered energy consumption.

A flying craft has an aerodynamic aircraft fuselage structure preferably disc shaped. A pair of coaxial electrokinetic motor-generators are mounted concentrically, and preferably centered within the disc shaped structure of the craft. Each of the motors is toroidal in configuration, providing a ring-shaped stator and rotor portions. The rotor portions of the motors drive counter rotating fans which are electro-magnetically levitated. The structure is open to the fans so that air may be drawn into the structure and expelled downward providing vertical lift to the aircraft. By use of auxiliary air braking flaps and electrokinetic thrusters, the craft may be tilted so as to develop a desired horizontal thrust. By impulse breaking one of the fans through tracking solenoids at different points around the stator, the aircraft may be made to rotate about its own vertical axis for changing direction. By a series of sudden braking of the motors the craft may be made to move by inertial reaction.

There have been past proposals for air vehicles employing the Coanda effect. In these proposals, a jet of fluid, usually air, is made to flow radially outwardly over 5 a dome-shaped canopy to create lift. A cross-section through the canopy is curved to follow a segment of a circle or it may have a radius of curvature that increases in the direction of flow. In the invention, the radius (r) of the canopy curve decreases towards the downstream direction (x) in a way that is related to the decrease in the width of 10 the jet as it flows over the surface. This means that the radius of curvature decreases (instead of increasing) towards the downstream direction with the rate of decrease being progressively less rapid towards the downstream direction.
