Rotor Platform of Aerodynamic Force and Method of Aerodynamic Force Generation

Abstract

Rotor platform of aerodynamic force is meant for generating aerodynamic lift force in horizontal position and aerodynamic transverse force in vertical position, with further practical implementation as a robust power installation of transport vehicle facilities. The principle of operation of the platform is based on the well-known Magnus effect—generation of transverse force acting on an object spinning in the ambient air flow. The basis of the construction is the unit of several coplanar rotors, wherein the rotors spinning is caused by the air flow force and the rotors provide the summed value of the generated aerodynamic to force.

1 . A rotor platform of aerodynamic force comprising identical central and lateral rotors with load-bearing elements of logarithmic spiral profile, characterized in that the rotation longitudinal axis of the central rotor is fixed in the platform frame, whereas the rotation longitudinal axes of the lateral rotors are rigidly tied by cross-members, with the centers of the latter ones, via bearing units, being coupled with the fixed longitudinal axis of the central rotor. 
     
     
         2 . A method of generating aerodynamic force by the rotor platform according to to  claim 1 , characterized in that the given aerodynamic force represents the sum of the forces generated in the nearest to the rotor air flow, due to the flow with natural velocity, whereas on each consequent rotor under the effect of the flow with the summed velocity generated on each preceding rotor due to the summation of the rotation velocity and the flow velocity, being mathematically expressed as follows:
