摘要:
A hull mounted, steerable marine drive system having trim actuation is both steerable through 360 degrees and is trimmable in a range of from approximately +3 degrees to approximately −15 degrees. The marine drive system includes a watertight enclosure assembly for sealing the hull, which is adapted for keeping much of the marine drive system from being exposed to water. The enclosure includes a gasket flange plate, a retention plate and a folded gasket. The gasket flange plate closely follows the contour of the hull and enhances the hydrodynamic and wake performance of the present marine drive system. Further, marine drive system includes a forward-neutral-reverse (FNR) transmission assembly, a drive unit assembly having a trimmable upper unit and a steerable lower unit, a steering actuator assembly, a trim actuator assembly, and, preferably, trim foils for enhancing lift to assist in getting the boat up on plane.

In a propeller system a process of dynamic energy-saving superconductive propeller interaction with a fluid medium comprises providing a perforation on the working blade surfaces having the different pressures, with an element possibility of the dynamic fluid medium flow connection between said blade perforations; and modulating a value of said connection of the blade so-called “breathing surfaces” in dependence on a change of a value of at least one controlled characteristic influencing a dynamic energy efficiency of a propeller process such that a dynamic structure-energetically optimization of said modulated surface-energy interaction is provided.

The present invention relates to SMAs (self-moving apparatuses) which use any type of propulsion means, including, without limitation, an FPGB (propeller-gear block) comprising an FP (propeller) and a drive for supplying power thereto. More particularly, the present invention describes: novel forms of energy-efficient (economical) FPGBs; and novel conceptual designs for SMAs, which make it possible to create economical SMAs with high specific power. The invention can be used for creating novel energy-efficient types of SMAs, and for the widespread (mass) use of compact and environmentally-friendly electric engines instead of environmentally detrimental and bulky internal combustion engines.

The invention relates to a device (100) for reducing the driving power requirement of a watercraft, comprising a flow guiding surface (10) from which at least one first fin (20) projects. A first end of said first fin is fixed to the flow guiding surface (10), and a second end (23) of the first fin is embodied as a free end.

A propeller used in aircraft/sea vessels, pumping systems, wind and hydraulic turbines is provided. Propeller blades are distributed around the propeller hub and positioned so as to set an angle with the axis (x) of the propeller hub, to a concave curvilinear contact surface formed on the suction side of said blades that push water and to a convex outlet surface which follows this concave surface and is shorter than said concave surface.
