Titanic Engine model in Autodesk Inventor

[telhacerta]

This is so beautiful.

[Allan4311]

hello to all very nice reproduction, but has anyone as far as he crankshaft and connecting rod. thank you

[pgergely13]

Is that little rods appear from 0:14 to 0:21 the cam controls? And after down there in tha crankshaft the turning of these rods?

[Phocusali]

What an interesting animation. I shall visit the page you reccommend. It seems to me that the engine is a twin compound rather than a triple expansion engine. I wondered about four cylinders. But a beautiful job anyway.

[crucialconflict02]

excellent.

[DaBoogie049]

beautiful model of a beautiful engine

[1Davo2]

Having used AutoCAD myself, I am very impressed with that!

[druisteen2]

titannic has turbine ...........

[Fast355]

@druisteen2 On the center propeller only. The outer propellers were driven by counter rotating, 4 cylinder triple expansion steam engines.

[krugerfuchs]

that's really cool man

[markushne]

very good job!!!

[MartyMartin87]

Fantastic

[Stanleyguy101]

Holy Cow ! This is amazing

[stepheng1483]

These engines must have been a magnificent sight when working. I believe they were the most powerful reciprocating steam engines ever built.

muy muy buen trabajo..

really good good job congratulations

[Mitsugejl]

Nice job i must say. Took some time i guess :)

[ZVdP]

A few weekends I guess (there was a time constraint, because of this there are a few features missing on the model).

I do remember though that placing all the bolts and nuts was very tiresome, there are over 2000 of them :)

[CianThEfuR]

very impressive

[NJRocks281]

And you know what makes it all go...men with shovels

[er10b]

@NJRocks281 and about 24 of them too! I bet you they had to keep spare men on board to help feed the boiler's monster appetite for coal

[Franko94]

wow, this is amazing. the only thing i am confused about, is that this is a triple expansion engine, right? Why does it look like there are 4 pistons? or is it a quadruple expansion?

[ZVdP]

It was a triple expansion engine.

But the first and the last piston both operate at the same pressure, so a triple expansion with four pistons. In detail: steam enters the high pressure piston, then goes to the intermediate piston. From here the steam is divided in two and both streams go to the two low pressure pistons.

[Franko94]

thats amazing. After i left that comment i actually just typed in 4 piston triple expansion engine, and I got that explanation. Very great engineering.

[krehall]

@Franko94 This engine has 2 low pressure cylinders and is balanced by the Yarrow, Schlick and Tweedy system.

[lionellines1900]

what  are the duel ones cycling in between the large ones?

[ZVdP]

They control the steam valves, to let the steam in the cylinders.

It is a part of the 'Stephenson linkage'.

If you are interested, this is a very detailed page about Titanic's engines:it is called 'Titanic prime mover' on 'Titanic-encyclopedia'.

@lionellines1900 Stephensons' Valvegear

The Olympic Class Engine to perfection.

good job :)

wow.. I cant beleive you made that yourself!?

[Andy120290Returns]

Neat!

[Miningpower]

That is really well done! To bad there weren't more known measurements on Titanic's engines.

[vector6977]

its all in the blueprints.

[TerminatorFRA]

@Miningpower I can answer you for the torque. We have the maximum power of 15000 hp at 75 rpm, this gives an astonishing 1400000 Nm or approx 140 ton-meter.

Now when modeling the behaviour of it in excel, for the maximum torque at 0 rpm, I found between 230 and 250 ton-meter, it seems to be the highest maximum.

[petermines]

Very well done ZVdP.

[tootime576]

Awsome! Did you have plans?

[ZVdP]

Thanks.

I used plans of Britannic's engines (they are very, very similar to the ones of Titanic) which you can find on the internet and also fotos of the engines in construction.

[tootime576]

Really? I have been looking and can't find any. Do you know of any links or sites where they are?
