BACKGROUND OF THE INVENTION

Technical Field; Prior Art

This proposal relates to hydrodynamic and electro-mechanical structures which provide effective accumulating energy transfer especially to universal motors and turbines. Conventionally there are known heat engines and turbines widely used in motor vehicles and other moving and static power sets. A common principal defect of most of them is their low about 40% total efficiency. Their imperfect general technology leads to power wasting, large and costly fuel consumption, and non-prospective burning out their combustibles.
These conventional heat engines and some turbines are ineffective because of high energy dissipating. They pollute the nature and carry huge costs to end users. The most of them literally squander and through out more than a half of energy they have produced.
This proposal provides effective energy transfer with cyclical energy accumulation and high power ratio based on clean natural technology. The subject matter of this turbotechnology are axial bispindle multistage hydrodynamic turbines with primary and guiding wing-blade stages connected to their contrary rotating spindles—all installed inside closed liquid tunnels with an axial-flow propeller pump working as self-booster for itself and for turbines, accumulating energy cyclically by and in the potential operative liquid flow in the said tunnel.
These developed solutions turn the turbosets into effective motors and/or turbines and/or independent power units for diverse purposes.
Any direct prior arts connected with my proposal or some analogies were not found. The initial prior art ideas of this cyclical technology were gifted by our Mother Nature. My general circuit—self-boosting method is similar to human and mammal cordial systems philosophically.
Some fragmentary elements of testing closed fluid dynamic tunnels could be regarded like a far prior art details but these tunnels had never even been considered as a possible base for redeveloping into power units despite their formal high energy ratio.
This proposal unites, combines and develops further some of technological particularities of:
closed testing wind and water tunnels,
fluid dynamic axial multistage turbines
Hydrodynamic transmissions general flexibility.

BRIEF SUMMARY OF THE INVENTION

It is an object of this proposal to provide a real effective universal power set based on accumulative low-power-dissipating technology.
It is another object of this proposal to provide clean natural technology without any pollutions and other harm emissions.
It is another object of this proposal to provide multiple power and design versions of effective clean motor sets to meet any of application requirements.
The nature and substance of hydrodynamic closed loop turboset-selfbooster and turbotechnology are axial multistage bispindle concentric turbines installed inside closed loop tubular tunnel with an axial-flow propeller pump which, impelling the operative amount of liquid filled into tunnel,—works as a self-booster for itself and for all the turbines.
The said axial-flow propeller pump working actually in self-series accumulates the energy of the operative liquid, rising the pressure cyclically up to definite level—by design. The turbines, working in high potential liquid flow, develop needed level of energy and can drive various receivers of their power like electric generators, shown in present embodiment or others—alternators and/or mechanical transmissions.
This accumulative and low-dissipating turbotechnology provides high energy ratio by self-boosting axial-flow propeller pump working in self-series; bispindle axial multistage wing-blade turbines; a closed-loop common tunnel having inside the high-potential operative liquid flow with its cyclical energy replenishing and smooth hydrodynamic interactions. The turbotechnology is natural, clean, has no pollutions, harm emissions and substantial energy dissipating losses.

DETAILED DESCRIPTION OF THE INVENTION

The FIGS. 1, 2, 3, 4, 5, 6 show the preferred embodiments and arrangements of the present proposal its units, subunits, and their interactions.
A hydrodynamic closed loop turobset-selfbooster, its turbotechnology as illustrated in FIG. 1 includes at least an axial bispindle hydroturbine 20A installed into closed loop tubular liquid tunnel 26A with an axial-flow propeller pump 27. The definite amount of operative liquid which is completely filled into said tunnel is preferably a high density operative liquid under definite controlled static pressure. The hydroturbine 20A being bispindle drive two electric generators 28A and 28B by each spindle and could drive any other receivers of turbine's power in other designs. The turboset has a tunnel air-cooler 26E placed near cooling fins of the tunnel 26A, a kit of needed hydraulic and electric meters and general control panel 29G.
Another, a cascade embodiment of this proposal is hown in FIG. 2 where two axial bispindle hydroturbines 20A and 20B installed into their common closed loop cascade tunnel 26B. Also the electric generators 28A, 28B, 28C, pump 27 and pump's electric motor 27A, air cooler 26E, cavitation control valve device 26C are shown in FIG. 2.
The FIG. 3 illustrates the general design and technological structure of the said axial bispindle hydroturbine 20A, which includes:
(a) an inner turbospindle 21 rotating with its primary wing blade stages 21 when operating,
(b) outer turbospindle 22 generally rotating with its guiding wing-blade stages 22A when operating; both said spindles 21 and 22 are coaxial each to other,
(c) head double bearing 23,
(d) aft double bearing 24,
(e) wing blade adjusting control 25.
Any of guiding wing blade stages 22A has two adjacent primary wing blade stages 21A along their spindles respectfully.
The numbers of any blades in any stage 21A and 22A, the number of stages on both spindles 21 and 22 accord to specific designs.
The said wing blades 21A and 22A may be mono- and/or multi-element, and/or have slotted flaps, slats, flexible trailing edges.
The wing-blade-stage-spindle-turbine design includes and provides:
(f) correct guiding when operative liquid flow is waving between adjucent of both spindles blade stages 21A and 22A.
(g) needed hydrodynamic conditions for both said turbospindles 21 and 22 to rotate in opposite directions.
(h) obtaining maximum torque on both turbospindles 21 and 22 in their optimal revolutions,
(i) preventing extra-turbulence of liquid flow of 29F in order to protect the cyclical accumulation of pressure in high potential flow 29F.
The FIG. 4 shows the plan view of turboset; directions of rotations of primary wing blades 21A and guiding wing-blades 22A according to the liquid flow 29F in the tunnel 26A; turbine 20A electric generator 28A; tunnel 26A; cavitation control valve device 26C.
The combined drive brake of the outer turbo spindle 22 can be used to make the outer spindle 22 with its guiding wing blades 22A static in some cases if needed.
The FIG. 5 is a schematic cross section of hydroturbine 20A with both concentric spindles 21 and 22, primary and guiding blade stages 21A and 22A, blade controls 25.
The symmetrical and concentric placement of wing- blades 21A and 22A, exemplary number of blades in their stages, opposite spindles' rotations in moving high potential liquid flow 29F in regular order of work are shown.
The fragmentary cross sectional view of FIG. 6 shows how the primary wing-blade 21A, guiding wing-blade 22A, adjusting wing-blade control 25 are placed on their inner 21 and outer 22 turbospinldes respectfully each other and fluid flow 29F. The average adjacent wing-blade stages spacing “S” is shown.
FIGS. 1, 2, 3 illustrate also where are flow straighteners 26S which provide needed turbulence limitation and volume equalization of the high potential flow 29F caused by dynamic state of operating liquid inside the tunnels 26A and 26B double bearing 23, 24. The visor 26V is used for visual observation of high potential liquid flow 29F when the cavitation control valve device 26C is tuning.

Combined Operation and General Interactions

The axial-flow propeller pump 27 driven by its electric motor 27A, working in series with itself and for itself as selfbooster inside hydraulically closed loop tunnels 26A or 26B impels the operative liquid. The pressure of said liquid rises from cycle to cycle up to a definite level forming inside said tunnels a stable high potential flow 29F which drives the axial concentric bispindle multistage hydrodynamic turbines 26A, 26B.
The adjusted by controls 25 wing blades 21A, 22A provide needed hydrodynamic lift forces in their stages for turbines spindles 22 and 22 forming their torques to drive electric generators 28A, 28B, 28C and obtain their power—all together and/or separately.
The orientation of wing blades in their adjacent primary 21A and guiding 22A stages forces the said flow 29F to wave between adjacent stages of wing blades and rotate the spindles 21 and 22 in opposite directions in regular working regime, in most cases.
The hydrodynamic design of all wing blades in all stages 21A and 22A, regular contrary rotation of both spindles 21 and 22, correct numbers of wing blades in any stage, spacing “S” between adjacent stages, appropriate velocities of the liquid and spindels' revolutions make the potential flow 29F smooth, correctly directed between any adjacent blade stages 21A and 22A without extra rumpling and messing of the flow 29F. This leads to the designed level of energy conservation of the high potential flow 29F after each wing- blade stage 21A and 22A. That is why the turbotechnology of this proposal is accumulative without big dissipations of energy.
In some cases often connected with starts and stops of turbosets' work, the guiding blades 22A and their spindles 22 can be static by control of the brake-part 22B if needed.
The adjusting wing blade controls 25 provide

- regulation of general orientations to any of primary and/or guiding wing blade 21A, 22A in order to have appropriate hydrodynamic angles of attack and downwash between any adjacent wing blades, respectively to liquid flow 29F direction and spindles rotations

limitations of possible extra vortices in multiple wing-blade rotative interactions
needed regulation of any local wavings of fluid flow 29F between adjacent wing blades in order to make the flow 29F transfer from any blade stage to adjacent stage as smooth as possible thus supporting the general accumulating technology inside the tunnels 26A, 26B.
The tunnels 26A, 26B can be filled by various liquids with relatively high density such as various kinds of salt water, organic solutions, bromides, heavy antifreezes—if needed and designed for specific conditions. The sum volume and initial increased static pressure of the operative liquid inside the tunnels 26A, 26B correspond and depend on type and particularities of liquid and pump 27
The possible local cavitation of liquid flow 29F is limited suppressed and/or depressed in regulation by pressure control valve-device 26C with springed piston which can provide the initial calculated static pressure of operative liquid in the tunnels 26A, 26B for specific design versions
The total power of all driven electric generators 28A, B, C (or other energy receivers) is the common power of the hydrodynamic closed loop turboset, as a motor unit. The initial and operational power for pumps 27 electric motor 27A and air cooler 26E can be provided by any of electric generators 28 with usage of matching electric battery and charger set 28 control 29G.
The hydrodynamic closed loop turboset-selfbooster operates as ecologically clean motor unit based on natural turbotechnology which has no harm emissions and/or pollutions. The power ratio and common effectiveness are high in multiple design versions including various series and parallel schemes of turbosets with equal or different power levels.
