    摘要: A low-cost viscous-drag-reducing cladding for a ship's hull comprising airbags whose outer surfaces are adapted to be water repelling. Each airbag comprises a plenum that comprises substantially open space, which does not obstruct the flow of air through it. The airbags are inflated with compressed air to a pressure higher than the adjoining hydrostatic pressure. The airbag material comprises a reinforcing fabric, which is adapted to withstand the forces encountered during operation, and is sealed with a sealant so as to be made substantially impermeable to air. The outer water-repelling surface of each airbag is connected to a plenum by means of restrictor holes. Air flows from the plenum through the restrictor holes into the water-repelling layer.

    摘要: A wind-water machine set is an evolving jet machine that moves the internal engine to the outside of the sleeve to work, instead of using a water jet as the main and air-jet as the auxiliary. When a ship uses multiple groups of wind-water machine set, there is a master control center for overall control and coordinated operation. Controlling the propulsion system makes the ship move forward and backward in an orderly manner. Control the surfing system to eliminate the bow water resistance and cooperate with the propulsion system. The steering control system is controlled to make the ship easy to operate the steering. Control the balance system to keep the ship balanced without swaying the roll angle. Control the draught system so that ships do not need ballast water. So that the ship can sail at super high speed, super fuel-efficient and safe.

    摘要: In the absence of inventive practice, the hydrodynamic flows on both sides of a vertically oriented bluff body (e.g., cylinder) traveling through water tend to hug the bluff body proximate its curved back surface and to converge behind the bluff body, resulting in lateral sway of the bluff body. Exemplary inventive practice provides for attachment of a pair of waterjet-streaming devices at opposite axial ends of a bluff body such as a cylinder. The waterjet streams discharged by the two inventive devices, which adjoin the vertical bluff body, deflect the hydrodynamic flows on both curved side surfaces of the bluff body. The inventive apparatus thereby encourages a continued approximate parallelity of the hydrodynamic flows behind the bluff body, resulting in significantly greater stability of the bluff body. Some exemplary embodiments of the present invention provide for attachment of a single waterjet-streaming device at one axial end of the bluff body.

    摘要: The invention relates to a maritime transport system for oil and the derivatives thereof, which includes a tractor unit with a device for driving at least one floating, rotary spheroid container. The at least one container has two semi-spherical domes, an upper one and a lower one, that are closed at the base end and open at the other, the base of each containing a flat surface. Both domes are assembled with the open ends facing one another and are joined at the circular perimeter thereof by a fitting belt with securing device and a gasket, both being solidly joined together. Inside the container are disposed an upper structure and a lower structure that are solidly connected to connecting beams, defining a self-supporting cube-shaped cage with projecting rotating devices and multiple individual housing cells for at least one tank of fluid to be transported.

    摘要: The present invention provides a movement device comprising a shell, and an outer fluid channel and an inner fluid channel are sequentially formed in the shell; the outer fluid channel communicates with the outside through a plurality of first ports, and the inner fluid channel communicates with the outside through a plurality of second ports; flow disturbing devices concave and convex relative to the surface are arranged in the outer fluid channel; the pressure difference generated due to different flow speeds between the outer fluid channel and the inner fluid channel serves as the propelling force source of the movement device. A pressure difference transferring circle formed around the shell by the pressure difference between the inner layer and the outer layer is used by the present invention for increasing the traveling speed of the movement device.
