The present invention relates generally to a novel and unique indirect drive unit apparatus, and a method and system of using same.
More particularly, the present invention relates to to a novel and unique indirect drive unit apparatus which can be used with fluid from a gas- or electrically-driven pump or air from a jet turbine, and a method and system of using same.

SUMMARY OF THE INVENTIONThe present invention provides n indirect drive turbine apparatus, comprising: a power source; an indirect drive turbine driven by fluid flow supplied directly or indirectly by said power source; said indirect drive turbine having a drive shaft, a plurality of stages of turbine blades and stationary stator vanes to redirect said fluid flow from a first stage of said plurality of stages of turbine blades and stator vanes to a second stage of said plurality of stages of turbine blades and stator vanes; and whereby each of said plurality of stages of turbine blades and stator vanes recaptures energy as the fluid circulates through said indirect drive turbine, and each time the energy is recaptured it increases force applied to said drive shaft of said indirect drive turbine.
An object of the invention is to use principles used in modern jet engines by recapturing spent energy by routing it through stages of turbine blades that turn a drive shaft, and then through stationary vanes to straighten out the flow to be used again by the next stage.
Other objects, advantages, and features of the present invention will become apparent to those persons skilled in this particular area of technology and to other persons after having been exposed to the present patent application when read in conjunction with the accompanying patent drawings.
With reference to
The exhaust pipe 12 is necessary only if a gas engine is used.
The arrows 21, 22, 23, 24, 25, 26 and 27 shown in
The size and shape of the turbine inlet pipe 16 will vary depending in part upon the volume of fluid being used.
The turbine shaft 17 can be connected at a first end 18 to, for example, a transmission (not shown) or a gear box (not shown) to power any external device (not shown) which requires power.
The turbine shaft 17 can also be connected at a second end 31 to run, for example, a generator (not shown) or an alternator (not shown).
The size and shape of the turbine exhaust pipe 19 will vary with the size and shape of the turbine inlet pipe 16.
The turbine exhaust pipe 19 will be open to the outside air when the fluid being used is air.
The apparatus 10 provides a continuous system wherein the fluid is circulated from the storage tank 14 to the pump 13, and then trough the indirect drive turbine 15, and then back to the storage tank 14.
The control valve 20 will control the fluid flow to control or regulate the speed of the indirect drive turbine 15, with a bypass back to the storage tank 14.
With reference to
The indirect drive turbine 15 can be used with fluid from a gas- or electrically-driven pump in a sealed system, or with air from a jet turbine or ram air from vehicle movement in a open-air system.
Forcing air or another fluid through a stage of turbine blades and stator vanes constitutes a first stage.
Each stage will recapture the energy as the air or other fluid which circulates through the indirect drive turbine 15.
Stationary vanes will redirect the flow in to the next stage of turbine blades.
Each time the energy is recaptured, this will increase the force applied to the turbine shaft 17.
By adding stages of turbine wheels and stator vanes, the indirect drive turbine 15 will produce more power.
The horsepower produced by the indirect drive turbine 15 could be more than the horsepower of the pump 13 or jet engine (not shown) powering the system.
A very important advantage of the present invention is that the gas engine 11 is not directly connected to the indirect drive turbine 15 by a drive shaft.
For example, the indirect drive turbine 15 can be connected to the prop of a boat, while the gas engine 11 can be located in the front of the boat with only fluid or hydraulic lines connecting the gas engine 11 to the indirect drive turbine 15.
As another example, the indirect drive turbine 15 could be connected to a rotor of a helicopter with the jet exhaust duct through the drive unit to the outside. This would constitute an open-air system, and would eliminate the need for a gear box.
The present invention also provides the advantage of permitting a small engine to be used for a mechanical gain from the indirect drive turbine 15.
The present invention also permits the gas engine 11 to be placed where desired to best utilize the space available.
The present invention will increase the power output of the pump 13 by double or more, depending on the number of stages of turbine blades and stator vanes the air or other fluid passes through. Within certain limits, the more stages, the more power.
This is accomplished by using the principles employed in modern jet engines which produce 80% more power by reusing spent energy by routing it through stages of turbine blades that turn the drive shaft 17, and then stationary vanes to straighten out the flow to be used again by the next stage.
The present invention also includes constructing a multi-stage turbine that can be used independently or indirectly through duct work.
The present invention allows the unit to be powered with fluid, which will make it more practical for use in cars, trucks, and other vehicles. This will increase the horsepower output, so that a smaller motor or engine can be used. This means that much less gas will be used.
The turbine 15 will be made up of turbine wheels with blades that will vary in size and shape depending on the pressure, volume, and type of fluid media being used.
A stage is one turbine wheel and blades and one set of stator vanes. Additional stages can be added as desired.
The turbine is capped off at each end with an inlet duct and an outlet duct.
It is important to note that the present invention can be readily connected to a transmission or any standard drive train. However, the engine used for the power source will not be directly physically attached to or be contiguous with a drive shaft.
There have been described hereinabove only several possible unique and novel embodiment of the present invention which can be practiced and constructed in many different configurations, materials, arrangements of components, sizes, and shapes.
It should be understood that many changes, modifications, variations, and other uses and applications will become apparent to those persons skilled in this particular area of technology and to others after having been exposed to the present patent specification and accompanying drawings.
Any and all such changes, modifications, variations and other uses and applications which do not depart from the spirit and scope of the present invention are therefore covered by and embraced within the present invention and the patent claims set forth hereinbelow.
