This proposal relates to fluid dynamic jet propulsion structures for motor vehicles. It also relates to jet motors working with nonfuel, noncombustible fluid propellants. The general idea and technological approach are similar to some test wind and water tunnels with their well-known high energy ratios, which never were used as a source of power.
The philosophical principle of this proposal is near to U.S. patent application Ser. No. 11/399,661 entitled “Hydrodynamic closed loop turboset-self-booster” and filed on Apr. 7, 2006 in the U.S. Patent Office. Said turboset, developed by present author, is a universal power unit based on self-accumulating technology of constant operative liquid, which drives bispindle turbines-turbogenerators (
In the current proposal the self-accumulating fluid-dynamic ring technology is developed for jet motors and their propulsion subunits in various versions for jet-propelled vehicles, including rockets.
Other prior arts directly related to “ring jet propulsor,” as a motor based on cyclically self-amplifying fluid dynamic propellant in a circled circuit, were not found.
This proposal developed for jet motor vehicles using gaseous and/or liquid nonfuel, noncombustible propellants includes:
The ring jet propulsor can be used independently and/or in multiple design applications with any kind of nonfuel accelerators forming an effective family of jet motor structures without conventional combustibles. The liquid and gaseous propellants can be used simultaneously working for a common united and combined acceleration structure of jet motors when needed by design. The said fluid propellants can be ambient like water or air, and/or stored aboard vehicles.
The ring jet propulsor can provide real effectiveness of water jet propeller motors for boats and ships in order to replace the conventional low-speed and low-efficient mechanical screw propellers as obviously outdated. The ring jet propulsor can provide real substantial increase of jet motors' thrust forces with effectively reducing their energy requirements due to self-accumulation technology developed.
The drawings are schematic and simplified for better clarity of solutions developed. In the drawings, closely related units and elements have the same numbers but different alphabetic suffixes.
This proposal includes a family of general fluid dynamic versions of ring jet propulsors, their units, assemblies, and arrangements, including various kinds of propellants.

Symbols:
The fluid dynamic ring jet propulsor is represented in several general arrangements and applications related to usage of nonfuel, noncombustible fluid propellants in jet-driven vehicles.
a) The intake slide-vane impeller 23 or 33 feeds the fluid propellant into its tunnel 21 or 31 respectively.
b) The axial flow impeller 22 or 32 works in actual series with itself, at itself, and for itself cyclically raising the propellant pressure inside the tunnels in about 7.5 to 10.5 times, accumulating the energy of ring-moving propellant and forming high potential propellant flow in the tunnels 21 or 31 after definite numbers of circular cycles up to stable regime.
c) The outlet impeller 24 or 34 feeds the high-pressure propellant from said tunnel 21 or 31 to accelerator 42 or 52 providing additional pressure to the flow,
d) Said intake impeller 23 or 33 continues to feed said tunnel 21 or 31, which continues its dynamic pressure accumulation, mixing new feed-up propellant from impeller 23 or 33 with high-pressure circular flow inside said tunnel 21 or 31 and feeding said outlet impeller 24 or 34 respectively.
e) The sealing of ring tunnels with their high potential, dynamically self-accumulating flows is provided by sliding-vane rotary impellers of inlet and outlet units.
f) In case of liquid propellants the smoothing and pressure-rate regulations to the fluid-flow is provided by adjustable bypasses 38 and flow equalizers 35; the springed piston-valve 36 limits possible cavitation, prevents vibrations, provides smooth interactions among all fluid-connected units.
g) In case of ambient water jet propulsor for ships and boats the pressure of propellant, discharged by outlet impeller, is the working pressure of the thrust force to the vehicle.
h) In case of combined propellant version the aggregated fluid-jet pressure provides the total united thrust force to the vehicle.
i) The method includes built-in noise absorbers, inlet filters, ejecting nozzles, and needed meters for adjusting and control.
