Abstract

The Propulsor includes a tubular oval ring and a duct assembly with their pumps, a nozzle ejector with a thrust impeller, a hydraulic pipe-connector with its valve-adjuster, a spring piston valve unit, and devices of motor vessels' hydraulic infrastructure.
The ring's pumps act in self-series, thus rising the water pressure inside the ring up to adjusted level. The static portion of the risen pressure is hydraulically transmitted to the thrust flow in the duct, thus providing a massive boost to the common thrust developed by the pumps of the duct assembly. The motor vessel gets boosted propulsion with larger thrust and correspondingly higher speed.

    RELATED APPLICATION
  • Pub. No 2008/0141652A1, Pub. Date: Jun. 19, 2008, and then titled RING JET PROPULSOR by the same author.
  • Said application is considered as abandoned now.

    • BACKGROUND OF THE INVENTION
  • This proposal relates to the hydrodynamic jet boost propulsion structures for marine motor vessels and deals with:

      • sealing gate-pumps, axial-flow pumps, water eject impellers,
      • series work of hydraulic pumps; reaction propulsion,
      • hydraulic valves, meters, general infrastructures ; thrust output.
  • The thrust and speed levels of the conventional motor vessels are evidently not high enough. The ships move slowly. Many kinds of maritime thrust propellers, water-jets, other regular devices look outdated, and have to be improved with substantial growth of thrust.
  • This proposal, as an improved redeveloped simplified version of said above abandoned one, suggests a method and its corresponding means for high thrust levels obtaining with usage of closed ring tunnel.
  • Any prior arts where a closed loop tubular ring tunnel were used in for a hydrodynamic boost thrust obtaining, were not found.
    • BRIEF SUMMARY OF THE INVENTION
  • The substance and key objects include usage of:
    • 1. A closed oval tubular ring tunnel with axial-flow pumps which work in series thus developing water pressure rise inside the tunnel;
    • 2. A jet-duct assembly with two sealing gate-pumps, a duct-adaptor, a nozzle-ejector with its thrust-impeller, a filter-intake;
    • 3. A pipe-connector with a valve-adjuster for proper hydraulic interactions between said jet-duct assembly and ring tunnel;
    • 4. A spring-piston valve for the hydraulically united structure in order to prevent possible cavitation, regular drive-adjusters, infrastructure.
  • Said above means provide usage of their corresponding, natural, and interdependent method where in:
    • a) the risen water pressure inside the ring tunnel is hydraulically and properly transmitted to the jet-duct assembly, which is protected by sealing gate-pumps, and farther to the thrust-impeller;
    • b) capacities and the heads of all the pumps and impellers in the jet-duct assembly are balanced and properly adjusted, the risen water pressure substantially contributes to the momentum part of the thrust and multiplies pressure part of the boosted in times thrust.

    • DETAILED DESCRIPTION OF THE INVENTION
  • The Ring Boost Propulsor (RBP) represents a technological method which is closely interdependent with its means all together developed for better thrust obtaining in energy saving manner.
  • Substantially higher levels of the thrust can provide new levels of speeds and other advantages for any kind of motor vessels.
  • The RBP includes hydraulically interconnected devices which rise the pressure of water flows and protect said risen pressure at all the steps thus rising in times the total boost thrust Tbt.
  • FIGS. 1, 2 demonstrate the BRP—set 20A which includes:
    • 1. A closed oval ring tunnel 21 with two axial-flow pumps 22A, B installed in series, a piston valve 24, a pipe-connector 26 with its valve-adjuster 27, meters 25;
    • 2. A jet-duct assembly 30 with two sealing gate- pumps 31 and 32, A nozzle-ejector 37 with its thrust-impeller 37A, a fairing cover 30A, an intake filter 36, a duct-adapter 33A, infrastructure.
      All the basic indicated water flows are shown in their developments.
  • FIGS. 3, 4 illustrate an arrangement of two RBPs 20A and 20B with an exemplary motor vessel 40. The closed tunnel 21, jet-duct assembly 30, pipe-connector 26 with its valve-adjuster 27, two water intakes Iw and two nozzle exhausts Ne, and other related and indicated elements are shown on this exemplary design.
  • FIGS. 5, 5A, being a scheme and its table, show and explain the flows' water pressure growth pattern with thrust forming and its step-by-step developing. All the water flows with their pressures are shown in corresponding hydraulic interactions.
    • Operation
  • The gate- pumps 31 and 32 fulfill the inner space of the jet-duct assembly 30 and oval tunnel 21 with ambient water; the pipe-connector 26 and then opened valve-adjuster 27 are used.
  • The axial- flow pumps 22A and 22B, working in series, rise the pressure of the flow Rf up to the definite level. This risen pressure is provided to the duct 33 due to the pipe-connector 26 and valve-adjuster 27; the common risen pressure Prd is protected by both sealing gate- pumps 31 and 32; the spring-piston valve 24 prevents cavitation.
  • When the meters 25 and 33B show a balanced pressure, the thrust impeller 37A starts and develops total thrust T′bt as a sum of momentum and pressure parts. The operation of elements 34, 35, 30A, 36, 37C, 37D and other—all indicated—is clear in drawing figures from 1 to 5A.
