im a Fire control Technician, so i work with torpedoes and tomahawks on submarines, look up SSGN on wikipedia if you want to see my work platform... Im on the michigan...

I really cant tell you anymore than that, im sure you all should understand...

My dad actually worked on the Mk 48, I was pretty impressed when he told me. He didn't tell em about the steam engines. He was also an accountant for the Shuttle program, but that came up during a discussion of advanced knife manufacturing processes involving putting two different forms of steel together. (NOT electroplating or blast welding)

The Japanese have been doing that for a couple thousand years. Samuri swords are made from two seperate pieces of steel. A hard, but somehwat brittle wedge for the the sword's edge, and a more pliable (less brittle) and more massive main piece. The resulting blades are generally considered to be the finest edged weapons ever made.

the most fun, not to mention the ship goes to sea just for my job...

@seeking, they dont use steam engines in torpedoes, just the same basic design as the engines shown

That engine design is flawed.

a proper steam engine is double acting, that was only single, efficiency just went out the window.

and it doesn't have a condenser to reuse the water, more efficiency loss.
EDIT: reading farther, it actually does have a condenser, I stand corrected.

never mind the ridiculously short stroke on the piston, and the overly complex motion used, there's no way either of that helps efficiency.


as interesting as it is, it's worthless as anything more than a conversation piece. :roll:

on the other hand it is fun to watch. :D


EDIT:
now I want to build a Steam engine... :(

Again, NOT an existing method (at the time). They developed a method of differing materials specifically for the retro thruster nozzles. It turned out to be just peachy for making knifes, to.

@ Judgement: Actually, if you think about it, it is very similar to a regular piston system, and actually isn't all that complex. You know how the piston sleeve in a regular piston engine is stationary? That requires the piston shaft to have a pivot in it. In this steam engine, the whole thing pivots instead. I did this once using legos by making a primitive air engine with just bricks. The entire piston assembly tipped back and forth, and it was nowhere near efficient. Then again, I had made pistons out of 2X2 bricks. If I had used Lego pneumatic pieces, then you could get some efficiency.

@judgement, the engine design is extremely efficient, but only with several cylinders, at least more than two, allowing for "exhausting" when the opposite(or the second cylinder away fires...6cyl) due to the motion of the swash plate, it allows for perpetual motion of an angular spacer, look into it more and youll see how well it works

That won't effect efficiency - in any case, you need to supply steam to the other half of a double acting cylinder.

It will affect power to size ratio, but that's not efficiency.

Does that thing kinda look like a big cat to you?
