Flash Steam Engine powered tether boats

I recently ran across the flash steam engine powered tether boats and it is amazing how much speed they can get out of them too.
They had some information on them here http://www.onthewire.co.uk/hydlist.htm
a 120mph steam engine powered hydroplane http://steamcar.net/hydroplane.html

The first video I ran across with one running fast:
British A/S class tethered hydroplane (1 min 51 sec)


Flash steam tethered hydroplane (0 min 32 sec)

Yes I have built several steam engines over the years. I find them to be fascinating watching them run at low RPMs with all the parts moving about.

The big one in the back is one I built many years ago in the school shop class. It is self contained with its own boiler.
The other two were built years ago but more recently though. They still work too. I have some more, but I need to post pics on them when I get around to it.

If anyone runs across more information on these flash steam power engines I would really appreciate it if you would pass it along here in this thread.

Thanks!

Here are some pics of my Flash Steamer OOYAH.
The engine is designed around R Kirtley's 120 mph Tethered Hydro, he is the chap with the blue skip cap on the Vid.

My engine is 1.25" bore x .75" stroke Uniflow Poppet valve engine.
Boiler is 32 ft of 316 St/St x .25" dia all encased in St/St casing and powered by 3- burners paraffin ( Kerosene ) each jet with .025" dia hole.
The boat is radio controlled by steering and stopping, very much light the blue touch paper and stand back.

Here are some pics of the engine and coil build,I hope you like them, the boat is named OOYAH after the shout one gives on touching very hot steam pipes , along with other expletives.
George.

Congratulations on your success, that was a great build and I loved your pics too.
I found it interesting in the last pic where the heat of the steam caused the metal on the engine head to get discolored a little too.
Thanks for sharing.

Hi Earl,
That pic of the cylinder head showing the burn marks is only after 2- runs of about 5mins, it will eventually be burned black.
The pipe coming from the boiler casing actually glows red in a diffused light and when you look down the flame tubes when the engine is running the St/St tube is nearly white hot and at the tail end of the coil ( the cold end ) it's bright red.
Here is a pic of my first engine which was 3/4" bore x 3/4" stroke with 22 ft of tube and this was good for 25mph. it is completely burned black compared to the new engine just installed and after a few runs is beginning to go black.

George.

That is amazing what one can get a steam engine to do.
For years I just assumed the steam engines were all low rpm high torque engines (albeit we had steam turbines of course). Anyway discovering that guys were getting steam engines to turn super fast RPMs was a big surprise discovery for me.
So way to go, and thanks for sharing, we all appreciate it.

The Stanley "steamer" car(1902-1924)were also flash steam power and could be ready to go in a few minutes from cold!
