    摘要： This disclosure is related with propeller noise and cavitation abatement in applications like propulsion, ventilation, pumping or turbine systems on fluids by novel techniques that allows stronger propellers with improved laminar flow by means of a propeller which consists on a rotating cylindrical block or a truncated substantially conical block with one or more tunnels around it rotational axis, said block also may have flow-guiding structures at both ends that help to keep the fluid's laminar flow when it is mixing fluids with its environment, having the rotating block tunnels with either substantially circular shaped cross-section or variable shape cross-section from substantially circular to irregular oval measured in perpendicular plane to the rotational axis whereby it smoothly accelerates fluid or gas by means of either centrifugal or axial movement, also including Dynamic Balance or Imbalance or Torque Modulation Means that modulate specific vibrations which generates sound waves.

    摘要： This disclosure is related with propeller noise and cavitation abatement in applications like propulsion, ventilation, pumping or turbine systems on liquid or gas fluids working like a propellers, pumps, fans or turbines, by novel techniques that allows a stronger propellers and improves laminar flow and allow a smooth acceleration or deceleration of the liquid or gas by means of a propeller that consist on a rotating cylindrical block with one or more tunnels around it axis, said cylindrical block also may have flow separators structures at both input and output that helps to keep laminar flow of the fluid or gas with it surrounding media, having This rotating cylindrical block tunnels with either circular or irregular oval section that accelerates fluid or gas by means of both combined centrifugal and axial movement.

    摘要： A lightweight vehicle which is operational on water, mud, marshy areas and other ground surfaces which includes a raised main frame upon which controls are provided for independently rotating at least one pair of drive drums which are mounted on opposite sides of the main frame. The drive drums are of a hollow cylindrical configuration and of a size to provide sufficient buoyancy to allow the vehicle to float on water. Each drive drum is provided with a spiral flute for developing propulsion and is driven by one or more hydraulic motors mounted axially with respect to the drum. Cutter bars are mounted to the frame and extend toward the ends of the drums to prevent debris interference with the drive shafts or bearings on which the drums are mounted.

    摘要： A propulsion device comprises a circular series of inclined airfoil elements. Each airfoil element is connected along its upper side to a rigid plate member, which is adapted to be rotated at high speed via a motor output shaft. The airfoil elements are oriented on the plate such that their vacuum-inducing surfaces face upwardly and outwardly of the circular series, and their pressure surfaces face downwardly and inwardly of the circular series.

    摘要： A propeller assembly comprises a plurality of hubs mounted for rotation on an axis which is transverse to the direction of movement of the boat, each hub haVing a plurality of radially extending blades which are curved and present crowned, convex surfaces to the water. The assembly is disposed, either within the boat or attached to the rear transom, so that when the boat is in motion the hubs are tangent to the surface of the water and press down on the surface of the water, and the blades slide into, and out of, the water endwise. The blades on the hubs of a paIr of hubs are opposed and angularly related one to the other so that they impel water inwardly toward one another and back, or outwardly away from one another and back, but not upwardly.
