Definitions

  • the invention refers to a new power ship and vessel and/or fluid propulsory systems,which consists of, new thrust hydrodynamic reaction wheels and/or new thrust hydrodynamic axial flow reaction turbines.
  • propulsory systems consist of,one and/or more, single and/or multi-stage, thrust hydrodynamic reaction wheels and/or thrust hydrodynamic axial flow reaction turbines,mounted at any desired place on the vessel, according to the rules of mechanics and of hydrodynamic propulsion.
  • the thrust hydrodynamic reaction wheels resemble to, a wagon wheel,whose spokes are hydrodynamic blades, helicoid or not helicoid,and/or conventional propeller,which bears on the circumference of its blades an annular ring,and consists of, one annular ring properly formed,which bears on its internal surface,in one and/or more stages along it,radially arrayed hydrodynamic blades ,helicoid or not helicoid, and/or conventional propellers,with and/or without various types of hydrodynamic cages and/or hub,within of which hydrodynamic cages they revolve freely (turbines),been supported or not supported by the hydrodynamic cages, thru one and/or more axles,fixed and/or revolving,with and/or without ball bearings, wheels,and/or gears, driving and/or not driving,fixed and/or revolving.
  • the purpose of all the mechanical propulsory systems is to convert the kinetic energy provided by the propulsory engine,mainly in the form of the conbination of torque and revolution of a shaft,in thrust along the vessel,in order to overcome the total propulsory resistance of the vessel (Rt).
  • the invention aims to the improvement of the above mentioned disadvantages of the conventional ship and/or fluid propulsory systems,so that,to improve their efficiency and the competability of sea transportations.
  • Basic elements and characteristics of the invention are: A. The use of thrust hydrodynamic reaction wheels and/or thrust hydrodynamic axial flow reaction turbines,single and/or multi-stage,in different combinations and variations,mounted to any desired point of the vessel, according to the rules and needs of the hydrodynamic propulsion and mechanics,which are driven mainly by their circumference,by the conventional ways of transfering and/or putting in circular motion wheels, as it is shown and graphically in the attached drawings No 1 to 28.
  • a thrust hydrodynamic reaction wheel resembles to a wagon wheel and/or cart wheel,whose spokes are hydrodynamic blades, helicoid and/or not helicoid, with and/or without hub,and/or a conventional propeller,which bears on the circumference of its blades an annular ring (ring,wreath),and consists of: 1.A solid annular ring (ring,wreath),figures No 1,2,3,4, of different types and shapes,figures No 2,4,9(2,3), properly formed and/or equiped with: I.Antisliding coating,e.g. from rubber,to the place where it is needed,for driving by contact by an other proper driving wheel,figures No 5,8, of the attached drawings.
  • the thrust hydrodynamic reaction wheel can be driven tangentially from its circumference by the conventional methods of transfering and/or putting in circular motion wheels,and/or be supported properly by the caging,in the case where there is no hub,figures No 11,12,17,of the attached drawings.
  • the thrust hydrodynamic reaction wheel is preferably supported by him thru only one axle,figures No 13,14,15,16, of the attached drawings,and the whole construction is more simple and less bulky. 2.
  • a thrust hydrodynamic axial flow reaction turbine consists of: 1.
  • An hydrodynamic cage which is composed of mainly three parts,the entrance/inlet,the exit/outlet and the trunk,which it is possible to be attached permenently and by will to one of the other parts,figures No 13,14,15,16,17(1,2,3) of the attached drawings. 2.
  • One and/or more revolving thrust hydrodynamic reaction wheels figures No 13,14(8),15, 16(6,7),17(9,10) of the attached drawings.
  • Fixed leading-supporting reaction blades placed by the inlet and outlet of the turbine figures No 13,14(5,6),15, 16(8,9) of the attached drawings. 4.
  • the propeller is assumed to act like a screw in a nut allowing for slip because of the medium and it would play no role if it were only a small part of a complete thread of a screw.
  • the momentum theory assumes that the propeller acts like an accelerator to the water passing thru it and the reaction so caused produces a thrust forward which propels the ship.
  • the volume of the water accelerated and the speed it acquires play an important role because it is their product that gives the thrust needed for the ship propulsion.
  • Each blade of the TYRW forms with the hub and the ring a slice of a cylinder the volume of which is swept by a complete revolution of the blade by 360° and itsjane is shifted by a distance equal to the length of the cylinder.
