6 Cylinder Radial Engine Steam or Air 30,000. RPM

6 Cylinder Radial Engine runs 30,000. RPMs on 100 psi air pressure. My techometer says, 30,000. RPMs thats unbelieveable so I went to a local electric motor repair shop and had it tested on their high tech electronic tach and it says 30,081 RPMs.

One drop of oil on each rod with the oil can, a few drops in the air intalk hole and one drop on the crank shaft is all it needs. The air blows oil through the engine as it runs.

We double checked the first Tachometer then checked it with a different Tachometer they both read 30K RPMs. I tried my old mechanical Tachometer it reads off scale. We used the electronic Tachometer to test a 3600 RPM electric motor it tested correct RPM. We used the electronic Tachometer to test a Model Airplane engine known to run at 28,000. RPM it tested correct RPM too. We retested my engine it shows 30,021. RPMs on 100 psi air pressure. Sound on video sounds different than being here.

A few people have asked if I have Plans for this engine. I don't have plans but maybe I should. The whole engine has11 different parts and 6 identical pistons and 6 cylinder walls, 6 rods.  It is a very simple design. I have plans for stirling engines, pulse jet engines and many other plans on ebay look for seller Scientificsupply.

Many people have ask me if I had plans for this engine. I have some hand sketches and notes but I need to make some good plans when I get time I will.

I'm guessing a 5 gallon air tank with 100 psi might last 5 minutes. As the pressure gets lower and lower in the tank the engine starts to run slower and slower. The engine will run full speed on 20 psi so a pressure regulator set at 20 psi would probably make the air in the tank last 2 or 3 times longer. The engine will run on 5 psi a pressure regulator set a 5 psi would probably make the air last pretty close to an hour.

They put a black mark on the flywheel with a black marker then the tach-o-meter looked at the black mark as it went around. This is the first time I have seen this type tach.

put your finger in that.

Needs oil

nice soud :D

@led4570 I agree, when it reved up I was thinking time to put on a helmet and get behind a blast shield...

[led4570]

I love it at "idle" speed........just like the "old" steam engines were.........but when you rev the hell out of it.......I tend to think......HAND GRENADE!!!

Be careful my Friend!!! Excellent work!!!

Awesome

[tanmaychhatbarme]

that old lovely sound of ww2 propeller engine... amazing. love it

[WelcomeWednesdayRock]

it that off air pressure the how does it make that sound

[Geoffrey2410]

BUT How is it lubricated?
