This invention refers to a method, a use and a construction/instrument for the reduction of the negative elements that follow the whirling of the air and/or of the sea by the revolving movement of blades, for propulsion or not.The purpose of this invention is that the blades of the propeller and/or of an other revolving movement instrument, with the positive work that they produce, they achieve at the same time the DECLENCHING of the TWISTING of the whirls, reinforcing, in this way, the propulsion of ships/crafts, airctafts and other propulsive means having a revolving movement. This invention provides a method where the TIGHTENING of the TWISTING which is developed inside the circumference that is traced by the tips of the blades of the propeller in the water and/or the air is OPENED with the creation of a decentralising point/part of the TIGHTENING of the TWISTING in question, a fact that reduces the caviation in the liquids as well.Thus on the blades of a revolving movement instrument a projecting arc/a packsaddle is created, which is in extension on the vertical radius that joints together the centre of the axis of revolution with the middle of the tip of each blade, so that the projection/packsaddle in convergence with the middle of the tip of the blade by opening the circumference that the tips of the blade trace in the water and/or the air, reduces at the same time the tightening of the twisting of the whirlwinds and/or of the whirlpools, having as a result the reinforcement of the revolving movement and/or of the propulsive movement.This invention can be applied in propellers of ships/crafts, helicopters, screw-ships, blades of the jets' turbines, torpedoes, missiles, wheels of vehicles, rims of vehicles, salvers of vehicles, fans, windmills and/or other propulsive constructions and or propulsive instruments having a revolving movement.This invention can be applied in propellers of ships/crafts, helicopters, screw-ships, blades of the jets' turbines, torpedoes, missiles, wheels of vehicles, rims of vehicles, salvers of vehicles, fans, windmills and/or other propulsive constructions and/or propulsive instruments having a revolving movement.The advantages of this invention are clear in the developmennt of the water propellers and/or of the air-propellers and/or of other instruments and/or constructions having revolving movement blades, for the reason that an essential resistance in the revolving and/or propulsive movement is reduced with the "OPENER OF THE TWISTING OF WHIRLS" having an essential financial return, since it increases the speed by the small horse power or the horse power is reduced by the same speed |
