The mechanism of the rotation body dynamics for generating lift and forward thrust for aircraft or water vessels applies to the generation of lift when fitted above a vehicle and to the generation of forward thrust when fitted to the front side of a vehicle, applies to aircraft in the case of utilisation of aerodynamics, to underwater vehicles or vehicles having underwater lifting or propulsion parts in the case of utilisation of hydrodynamics. The common feature is, firstly, the utilisation of the effect of a medium flowing over surfaces, a pressure reduction being produced for the surfaces over which the medium thus flows, said pressure reduction being called suck, and representing a pressure reduction in comparison with the quiescent pressure and in comparison with other surfaces relative to which the medium is not flowing past, either located opposite or when using there the effect of rotation in the same direction or movement at equal speed, of the surfaces, the second common feature is the knowledge that not only short and long surfaces of any type experience suck in accordance with the speed of a medium when said medium flows past, but also surfaces underneath an intrinsically rotating large vortex, and conversely surfaces which rotate in a corresponding manner underneath a standing column of medium. In this case, the supply and dissipation are of second priority, and, in particular, an absolute pressure increase, a relative suction reinforcement, can be achieved by indentation.
