Tommey Reed's Advanced Engine Design Series.

Hello,

Aussiebattler You're correct.

The facts are nobody really knows how it was built, in 1972 he could have used a Bitumen asphalt pump. The few photos with chain drive does show hydraulic pumps are being used.

The problem I have with a cone shape pump is the thrust bearing on it at high pressure, this will cause a piston effects as the pressure increase moving it away from the cone housing. Cooking oil rim jets mixing with air will cause the oil to increase in viscosity when it cools. I had this problem many times running cooking oil turning to a grease.

Initially I firstly thoughy the same but I later perceived that the cone and it's outer both revolved together so the thrust problem is eliminated. Still later I consiered that a far more friendly manufacturing technique was to use a seris of spiral cut plates with a partitian between rather than the cone anyway (as I believeyou have too)
I will post more detail if you are interested
Cheers

Hello Sky.

I fully understand your idea.

I done all the mathematics. Thrust and pressure are the key to understanding how fast and torque is generated. Hp=torque x rpm/5252

1900 rpm rotating a 12" diameter disk will take (3.14*1900)/60 = 99.43 ft/sec of thrust just to get it up to that speed. All thrust is lost and will not produce any mechanical load at that speed. the pressure would be greater then a 180 psi. This is why hydraulics is needed.

10 hp with a 24" 4 rim jet would need (26gpm x 500psi)/1714=7.585hp@ 100% efficiency running 1800 rpm.
85% efficiency is the real world in hydraulics not adding drag and other factors.

Cavitation is need to create greater output with pressure above 500 psi.

Hi Tommey, I am not good enough in hydraulics, so by my side I will give it up, but if you need my professional made technical drawings only contact me. You could even get my huge device free of charge. Would like to support you. It is still a great project and I am sure by knowing the project history that this technology worked well. Even in the past he faced problems by his second built that it started not as easy by low rpm as his first unit.
I have following suggestion which is super simple to build and to make tests without spending big money.
Take a  water hose with a pump and add a valve at the first part of the hose to let air in. (easiest walve would be a pc of pipe where you hold your finger on/off) 
Press the end of the pipe together to create a jet.
By this construction we can check the liquid-air relation.
You can easily check by which kind of input you get which kind of output...more detailed you could add a water wheel with generator...than you can check how much energy the pump needs and what kind of
energy the waterwheel creates.
I will also prepare a test like this in next time and update you.

Hi All,

Patent:
https://patents.google.com/patent/US6860251B1/en

It is my great privilege to talk to you, and I do thank you for that.
I do admire your dedication .
I'm quite savvy in mechanics.
I see most if not all pros and cons of your concept, design, practical application.

I might be right, I might be wrong,
but I am never trying to be nice guy, when evaluating somebody's intellectual property.
It either works or is not.
But if it doesn't work, it doesn't mean it can't work as a concept or as its modification.
We all are being scrutinized by others, who are likely, mostly, or totally driven by their emotions, 
- desire sometimes called opportunism  often filled with jealousy/ugliness.
I am on your site.

Hello Stivep,

As you may know patents cost money to keep them on file for 20 years. I couldn't afford to keep it active at that time.

As for the design and problems with the combustion chamber, it was a set back. But like all design failure, I corrected the issue and will correct the problem when I get extra money and better machines to continue the build.

Thanks for your interest.

Tom
