This is the first test run on steam. Wow, smooth and fast on a max steam pressure of 80 psi and 2700 RPM To see a description of the principal and run on air see movie • Rotary Piston Steam/Ai...
Hi Frenchie, The demand for steam is grater than the boiler can produce to keep the RPM high. So it slows down till I can build pressure in the boiler . Don
I think if you had one stainless steel pipe about 3 ft long 2.5 inch in diameter bolted to the intake port of your device capped at the other end and has a small injector port in the cap to inject the water into the pipe. You could heat the pipe glowing red hot and Mist water in to it creating superheated steam pressure directly into your device. You could use cover induction coils around said stainless steel pipe to create the red hot heat needed for super heated Steam
Hi Frank, this "test" engine has no seals. I am now building it into a triple expansion version, with seals. I have a dynomometer to hook it to when done. Don
Don Maguire I worked it out finally. it is the same like a cooker. If a cooker does not release the pressure it will explode. So it is indeed pure steam power but sill very amazing.
Looks great. Did your seals leak a little? Speed is good if it produces torque. Short of coupling to a generator and applying a load, how can the output be measured?
Hey don, I know this is an old video and it may have been addressed, but what size boiler did you have this hooked to and how much larger would it need to be to operate this motor under a load? What is the maximum pressure this motor could handle?
One problem i see is a little diameter hose going into a bigger hose or pipe. start big then go little if the intake pipe to the steam engine is a certain size then the pipe or hose coming from the boiler needs to be bigger than that intake hose or at least the same size. Instead of that giant boiler I'd use a set of microwave Transformers and graphite rods to create a plasma Arc to heat water instantly to superheated Steam to keep a constant High steam pressure look on King of randoms Channel ruclips.net/video/VTzKIs19eZE/видео.html to find out how to build one; and I would use the steam pressure to pressurize the seals to the crankcase to stop the leaking from the bearings if you can figure out how to make such a seal. I like the efficiency of this device because a utilizes I full rotation instead of half a stroke like most steam engines seems like it would have good torque.

I'm expecting some steam trains to not have pistons, but this instead.
nice work Don i love this design, i tried to come up with this same principle and failed
try your own
or steal a better one and be an artist , like picaso
Thanks to all of you below I finally worked it out and also some one suggested >>See "Bernulli's principle" and "Tesla pump"
See "Bernulli's principle", "Steam Injector" and "Tesla pump"

thanks
Hi, steam is made in a boiler, than goes to the "steam engine" where it turns the shaft and makes power.
Valeriy, this is not a turbine. It is a rotary piston engine.

It sort of braps like a Mazda wankel rotary :)
Hi, The deception above has a link that shows the design principal.

Looks like the engine Robert A Smith built for Henry Ford !!!
wonder what a prony brake measurement would say about horsepower?

Hi Don,
Do you have a patent? Do you sell plans or prototypes?
best regards
close that loop...
why does it crap out near the end? Seems to go for awhile then dies.
ik im very very very late, but I think its because the boiler lose pressure and cant keep up with the loss
Nice engine, but why so noisy?
Because it doesn't have muffler
WAY too inefficient
