WW1 torpedo engine?

OK, is this correct? is it truly a torpedo engine?

The 20,000 RPM figure could be off, or they could have geared it up to
that using a gearing system.
It definitely could be, it looks like it would fit into a Torpedo
housing.

I linked the site to a couple of the main Sub BBS's. I'll post again
if I see a valid response.

It's possible

If it ran at 20,000rpm you would need some serious gearing to turn the
prop at a sensible speed, maybe a typo for 2,000 rpm?

Alcohol and liquid oxygen in WWI? I would guess alcohol and hydrogen
peroxide. The Japanese have credit for using oxygen in their Type 93
(1933) Long Lance.

You need a serious gearbox for the counter-rotating props.

There was a flywheel powered torpedo in this era that turned the
flywheel up to 10k revs.

Back to the original question, I still haven't recalled anything about a
liquid O2 engine in Torpedo's. Since today is the first day back at work
I will ask around a bit, but I doubt there ever was such a thing

There was also a submarine version or byproduct Type 95.

Liquid oxygen has a density of ,85, and so you would still need a
large air tank for bouyancy, even if the O2 tank was small. Maybe not
so small, depending on the insulation. Fish are always near neutral
bouyancy, and some sink, some float,[ and some blow up. at the end of
run.] The WWI Brits retrieved floating misses and reloaded them. No
thanks.

Nobody used O2 or for that matter hydrogen peroxide during WW1. Nobody
used liquid O2 during WW2 for that matter. Attempts to use hydrogen
peroxide in torpedoes was post WW2. Using alcohol as a fuel on the other
hand is possible.

Em... did you bother to actually read either of those articles?
Neither the Type 93 nor Type 95 had a ->LIQUID<- O2 tank
It was compressed
Here is another hint, there is a (modified) Type 93 not 200 yards from
me, that I was just looking at last week (the Brother-in-law wanted a
tour of the Museum)

Where did I say they did?
Ralph
All the (modern) torpedos I am familar with are negitively bouyant,
when fueled and ready to go (war-shot). They would go very positive at
the end-of-run. They also tend to have a EOR scuttle valve now days
Exercise unist start out positive
In figuring the bounancy, don't forget all that air-space around the
engine, piping, cables and tanks, etc. Those area's add to the bounancy

The discussion started out about LIQUID O2 engines, you linked to
compressed 02 engines
What else would you have been refering to?
Jack Linthicum
What I said:
"Alcohol and liquid oxygen in WWI? I would guess alcohol and hydrogen
peroxide. The Japanese have credit for using oxygen in their Type 93
(1933) Long Lance."
Notice the difference?
"oxygen" not "liquid oxygen"

The Japanese O2 torpedoes used O2 gas under pressure.

Looks like Jack could have been a lol clearer, more then one person
thought that he was infering that the Type 93 used liquid O2
