<p>The invention relates to a propulsion mechanism with wings in cycloidal motion for aerial micro-vehicles, applying the functioning principle of the Schneider propeller used in the navy, for generating the lift of the mini-vehicles. According to the invention, the mechanism uses two coaxial propellers, named here rotors, in which the common shaft is horizontal when the vehicle is at rest on the ground, each rotor being provided with two, three or even four wings (), and the axes () of the wings () form with the rotors axes a flare angle Delta, which is a significant modification in relation to the marine propeller where the wing axes are parallel to the rotation axis, the mechanism for carrying out the motion of rotors is based on two original solutions, namely, the utilization of a circular cylindrical guide () for the cyclical pitch and the control by means of a gear () - rack () system of the general pitch, the circular cylindrical guide changing the cyclic pitch angle in conformity with a law which is correct from the aerodynamic point of view, and the control transmitted by the gear () - rack () system allows the variation of the average amplitude in conformity with the above-mentioned law, also proposing a system of controls, elevator, direction, ailerons, placed in the rotor jet, which operate in any conditions, in flight at fixed point, included.</p> |
