Titanic's Reciprocating Engines

[Cian O'Reilly]

Latest update on the Low Pressure Cylinder work on the engine...The 'feet/clamps' have been added to the Cylinder allowing it to be fixed to to the Y columns, the openings for the Piston and valve rods have been added as well as the feed Pipes from the Intermediate Cylinder to the LP Cylinder Valve Gear Steam Chest...other piping elements have been added, though but I'm sure there is loads more to do, including the piping from the drain cocks to the steam traps and of course the massive exhaust pipe that carries the expended steam from the LP Cylinders to the Turbine Engine is still to be added. I'm including a very 'rough and ready' low quality rendering of the animation for the LP Cyl elements, because frankly, I really like the 'Red Clay' rendering mode in 3DS Max

. It'll be best watched on loop...As ever, since there are some areas where some assumptions/guesses have had to be made due to lack of info, criticism and correction is welcome.
The Red rectangle visible in some of the images represents the height of an average human relative to the Cylinder...

Mini update here, I've added the LP Exhaust/Turbine feed pipe....

Looking great Cian, well done!

Hi All, latest update on the engine, The Intermediate Pressure Cylinder under construction, still a work in progress. Crits welcome.

I haven't done this before so I figured it would be interesting to see how they match up. It's an interesting way of finding errors. There are a couple of minor tweaks needed based on putting these two images side by side but happily, nothing major. One thing to note is that the camera in 3DS Max is very different to the one used to take the original Image of Titanic's port engine (photo Credit - Robert John Welch), so the match between the two images is far from precise, with the Welch image seeming to have an almost fish eye lens effect to it. I can probably emulate this in my modelling software, but for now this will do I reckon...Another thing to note is that I don't have a directional light set up in my image, so there are no shadows as such.

Hi folks, latest images of the engine project, this time rendered in Marmoset Toolbag 4. Three of the 4 cylinders are in place - in fact it's essentially what was in the last batch of images but fully rendered...Couldn't resist playing about with these images in Photoshop, so they've been tweaked a bit.

WOW!!!!!!
I can only imagine if you made the Turbine and Electric engines how AWESOME it'd look!

Nice work indeed. Don't forget the 10 holes on the crankshaft in the middle of the flywheels are just holes to bolt the prop shaft onto. Could slightly increase the hole size too. Still great work you are doing.

Yep, deffo, I hope to add the shafting here eventually, so that end will be re-worked, what you see is temporary.

Latest image of progress on the engine build...it's been at an almost total standstill for a while in terms of new stuff due to heavy work commitments. I've been adding detail to the forward LP Cylinder. As ever, basing it off the available plans - in other words primarily Britannic - I can't be sure that it applies to the Titanic. If anything is here that shouldn't be, let me know by all means. I'd rather be accurate and re-do things than leave inaccurate elements in place. So, whats new...? Well, I've added most of the pins/rivets to the cylinder head caps (there's a few more still to add) and also the lifting hooks used to remove it. More significantly though is the large structure at the forward end of the LP exhaust pipe. There are two apertures visible here in photos of the Britannic's engines, one small and one large. Unfortunately there do not seem to be any photos of what attaches to these openings, but according to the plans (again Britannic), these appear to be some kind of throttle or shut-off valve mechanisms. I've modeled them as best as I can make out from the plans, but I'd be reluctant to sign off on them as verified accurate. Again, any guidance would be welcome. Regardless, it's nice to be getting back into construction!

Hi All. Latest progress on the engine build, this time detailing the Intermediate Pressure Cylinder. Progress has been slow for a while now but hopefully picking up again now. Lots more still to do on this cylinder but it's moving along.

Seeing new updates always makes my day. Looking great so far.

Hi all, posting full colour renders of progress on the engine build. I've done more work on the throttle engine for the HP cylinder and am carrying out some improvements to make the other cylinders more accurate. One problem with the set-up of the High Pressure Cyl is that it's hard to see in any detail in photo's, being occluded by the massive exhaust to the LP's on the inboard sides and the smaller two on the outboard side. But clear visual reference has always been an issue, so one plows on

. Anyways, hope you like engines in the sunset!
