At helicopter the lift is produced by the aerodynamic profil of rotor and the equation is simple
At the levicrafts the sustentation is assited by antigravitational levitation produced by "Gyrodynes"
The "gyrodines" is an invention that consist ,further one helical, also in number no determinated of inertial disc in gyroscopic precesion and the equation is a few more complicated
The "Gyrodines" with "Atlas" Technology will allow us to levitate charge truely loaded and avoid the wáter resistance and to pass all obstacles type
The "Gyrodines" with "Atlas" Technology also will be use electric energy is to say "clean energy" decrease notably the level polution and global warming and neither say about to cheap the transport economic cost .
