sigpro Posted July 6, 2016 (edited) Hi people! Maybe some of you know me of the Star Wars forum. I am the proud builder of one of the UCS minifig AT-ATs and the Imperial Base, but I wanted to change and build something different. And after the Alebricks 2016 Lego Event I decided to build a minifig size submarine. I took inspiration on the S80 class under construction by Navantia, but I wanted it larger and more powerful. This is what I have by far...only the bow, the first module, and the sail. I don´t know when I will finish it, but I would like to build it with bricks for Christmas. The sub will hold 40 minifigs (32 for crew and 8 for a SpecOps unit)(like in the soon-to-be-built S81 for the Spanish Navy), 8 tubes (6 in the "real" S80), with an estimated length of 220 studs (approx). The design has been tricky, but it looks good. The real LEGO model will have detachable panels, so the inner rooms (control room, quarters, halls...) may be seen. I hope you enjoy it, and questions are welcome! Of course it must be finished and more detailed, but it´s promising SUBMARINO ENSAMBLADO 2 by green helmet spanish AFOL, en Flickr Edited March 31, 2018 by sigpro Share this post Link to post Share on other sites
Mr Greeble Posted July 6, 2016 Looks promising! Keep up the good work. Share this post Link to post Share on other sites
Kodan Black Posted July 6, 2016 Good start, the minifigs really help give it a sense of scale. Share this post Link to post Share on other sites
sigpro Posted July 17, 2016 (edited) Hi for the feedback! I have completed the skin of the third module, but inside is almost empty. Here is another pic for you to enjoy.

sigpro Posted July 19, 2016 Something important is the propulsion. The first sketch for a diesel generator (there will be 3). GENERADOR DIESEL by green helmet spanish AFOL, en Flickr The engines will be connected to an exhaust pipe that will drive the fumes through the snorkel. Enjoy.

Kodan Black Posted July 19, 2016 Ohhh, nice diesel generator. Are they mechanically linked to the shaft or just generate electricity and then motors drive the shaft? Share this post Link to post Share on other sites
sigpro Posted July 20, 2016 Hi Kodan, thanks for your comment and interesting question. My sub will work in a similar way that WW2 US subs (Balaos, Gatos) worked: the diesel engine(s) don´t drive the propellers; just provide electricty for a generator that drives the electric motor AND recharges the batteries while surfaced or snorkelling. German U-boats had a different power plant: each diesel engine crankshaft was connected with a clutch to the electric motor shaft (thus the electric motors acted as dynamos while running on diesel engines) and moving the propeller.

Rotundus Posted July 24, 2016 This will be a Leviathan when finished! Nice work. A monster build to be sure. The taper of the nose is quite interesting. If you care to share, I would like to know how you achieved all those intricate step-backs. I detect some complicated SNOT-work in there. Share this post Link to post Share on other sites
sigpro Posted July 24, 2016 Hi Rotundus, thanks for you comment. I have assembled the last module in LDD (with the pump-jet propulsion system and rudders) and its overall length is about 241-242 studs. The bow was very tricky to design, and I will update the Flickr album for everybody to see how it was build. There was a massive use of angle elements (part designation in LDD) with 135 and 157,5 degrees. Best regards. Share this post Link to post Share on other sites
Rotundus Posted July 24, 2016 Thank you. I'll be looking forward to examining it. I rather like your other builds that you have featured on Flickr, as well. I can see that HUGE is your favorite way to build. All are very well done! Share this post Link to post Share on other sites
sigpro Posted July 26, 2016 Hi again. Yes, perhaps I like huge MOCs...I hope this is not severe. I hope this pic of the bow is ok for you. Best regards. BOW CUTAWAY by green helmet spanish AFOL, en Flickr Share this post Link to post Share on other sites
Rotundus Posted July 26, 2016 Thank you for this additional pic. The taper of the nose looks a lot simpler than I thought it would be... Very elegant solution. Nice use of pin connectors for the last angle and cap. Well done. Share this post Link to post Share on other sites
sigpro Posted July 28, 2016 Enjoy the beast! I designed two versions on LDD. Version 1, reporting name "cucumber" for the towed array sonar on the upper rudder, a license I took from the Russian Akula and Victor SSN classes. SUBMARINO ENSAMBLADO 3 by green helmet spanish AFOL, en Flickr Version 2, reporting name "little cucumber", as the towed array sonar is more realistic and smaller.

sigpro Posted August 2, 2016 Hi again. I remodeled the hull because something "was wrong". It now features a bump along the hull, housing inflatable rafts, non-essential equipment, the snorkel tube... You´ll probably notice a few dark-gray tiles on the sail; the 16 short-range SAM missiles are housed there. NEW HULL FULL by green helmet spanish AFOL, en Flickr And a few pics of the torpedo room. 24 weapons, plus 8 in the tubes. This version carries 18 torpedoes, 3 cruise missiles, and 3 SSM missiles. There are 8 more weapons in the tubes (probably 6 torps, 1 CM, and 1 SSM).

sigpro Posted January 4, 2017 (edited) Hi again. I have just started with the construction of the real sub. This is the electric motor. As it is not easy to find pictures of submarine electric motors...I decided to build something simple. Here you can see the AIP tanks. The big one is the bioethanol tank and the small one is the oxygen tank. Ethanol is mixed with pure water, giving CO2, water, and Hydrogen. By mixing Hydrogen and Oxygen in a fuel cell we have water and electricity. Simple! Weaponry. 2 torpedos (inspired in the German DM2A4 torpedo), a Tomahawk-type cruise missile and a surface-surface missile (perhaps similar to the SubHarpoon SSM). No diesel engines, no propulsion. Three like this are linked to three electric converters to recharge the batteries and give energy to the electric motor. A low noise pump jet drives the sub. First step of the real MOC in the upper deck of the second section; bunks and control room. Lower deck of the second section. And the same part seen from the keel. Enjoy!
