Alfa Class Submarine

by

Alfa class submarines were a series of nuclear-powered submarines developed and manufactured by the Soviet Union during the late 1970s and early 1980s. These submarines represented a major leap forward in submarine design and technology and were considered among the most advanced submarines of their time.

The Alfa class was designed for high-speed, deep-diving operations and was equipped with a state-of-the-art nuclear power plant that allowed the submarines to remain underwater for extended periods of time without the need to surface for air or refueling. The hull of the Alfa was made of high-strength steel and titanium. It was designed to withstand extreme water pressures at great depths, making these submarines ideal for deep-water operations.

One of the most distinctive features of the Alfa class was its innovative propulsion system. The submarines were powered by a liquid metal-cooled nuclear reactor that generated steam to drive a pair of high-speed turbines. This propulsion system allowed the Alfa class to achieve high speeds and excellent maneuverability, even at great depths. The submarines were also equipped with advanced sonar and radar systems, as well as a sophisticated fire control system that made them highly effective in both offensive and defensive operations.

Borei Class Submarine

by

The Borei class, alternate transliteration Borey, Russian designation Project 955 Borei and Project 955A Borei-A (Russian: Борей, lit. ‘Boreas‘, NATO reporting name Dolgorukiy), are a series of nuclear-powered ballistic missile submarines being constructed by Sevmash for the Russian Navy. The class is projected to replace the Soviet-era Delta III, Delta IV and Typhoon classes in Russian Navy service.

My 3d model

Despite being a replacement for many types of SSBNs, Borei-class submarines are much smaller than those of the Typhoon class in both volume[8] and crew (24,000 tons opposed to 48,000 tons and 107 personnel as opposed to 160 for the Typhoons). In terms of class, they are more accurately a follow-on for the Delta IV-class SSBNs.

I’ve made this model both for display purposes and for R/C enhusiasts. There are two separate models for each purpose. Display model is approximately 21cms long to fit most 3d printers. Surely it can be enlarged as you wish if you have a large enought printer. The RC model consists of a shell and dive-rudder planes. It is approximately 1 meters long and has 1mm thickness. The paid model file pack includes both.

Leyland-Levend Public Bus

by

The Leyland-MCW B36D was an underfloor-engined single-deck bus manufactured for at least eighteen countries from 1949 to 1971. 3,564 samples were built at four factories (three in the UK, one in South Africa) from 1949 to 1971, with 1,299 Olympics (36%) built as right hand drive and 2,265 (64%) as left hand drive. It was a very durable heavy-duty bus which ran in arduous conditions for longer periods than ever envisaged by its designers.

300 of these B36D vehicles sold to the Istanbul municipal bus fleet in 1968/9 were named Leyland-MCW Levend, a word meaning a crack soldier. They served nearly to the year 2000. None were preserved 🙁

Here is Levend.

I’ve made a printable 3d model of the legendary bus which I’ve spent most part of my childhood and youth in it, travelling from place to place in Istanbul.

The bus model is animated, it has opening doors, running wheels, wipers, steering, suspension etc.

NR-1 Nuclear Submarine

by

Deep Submergence Vessel NR-1 was a unique United States Navy (USN) nuclear-powered ocean engineering and research submarine, built by the Electric Boat Division of General Dynamics at Groton, Connecticut. NR-1 was launched on 25 January 1969, completed initial sea trials 19 August 1969, and was home-ported at Naval Submarine Base New London. NR-1 was the smallest nuclear submarine ever put into operation. The vessel was casually known as “Nerwin” and was never officially named or commissioned. The U.S. Navy is allocated a specific number of warships by the U.S. Congress, but Admiral Hyman Rickover avoided using one of those allocations for the construction of NR-1 in order to circumvent the oversight that a warship receives from various bureaus.

This is a 3d printable model of the well known NR-1. The details are as faithful to the real thing as much as 3d printing requirements allow. The model details are improved for enabling an easier printing with minimal supports. There is also a 1meter hull available for R/C model builders.

X-Ray Class Submarine

by

The Paltus-class submarine is a Russian special purpose mini-submarine of project 1851.1. Two boats were completed – AS-21 and AS-35 as a follow up of the single “X-Ray”-class boat AS-23 (Project 1851). 

X-ray with various gripper options

The surface displacement is approximately 300 tons with a length of 98 feet (30 m). The propulsion comes from nuclear power with the operating depth in excess of 3,800 feet (1,200 m). The designer, according to Polmar was Sergei Bavilin who had designed the earlier diesel electric Project 865/Piranya small submarine of similar dimensions

Steam Engine Model

by

A steam engine is a heat engine that performs mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder. This pushing force can be transformed, by a connecting rod and crank, into rotational force for work. 

I made this model a while back. It was lying around in my hard drives, so i’ve given it a quick update and tidying to be a 3d printable project. Here it is, continue reading for more images and STL files.

Zeeteyfel Submarine with tank tracks

by

German engineers were able to create a number of interesting mini-submarine projects. One of them was a kind of crossing a submarine with a tank. This very interesting example was the ultra-small amphibious submarine “Seeteufel” (translated from German as “monkfish”) with a caterpillar mover. This boat was intended both for independent carrying out torpedo attacks and for delivering small groups of swimmers-saboteurs to the target of the attack.

.

Seeteufel was a rather unusual, even amazing, development. This “pocket” submarine was supposed to feel at home on the water surface, under water, and on land. This combat apparatus, as if descended from the pages of books by the famous science fiction writer Jules Verne. This boat attracted special attention and sympathy from the sabotage detachment “K” specially created in the German fleet. Members of this squad are accustomed to evaluate military equipment from the point of view of its combat use behind the front line of the enemy, so they could not but like this machine.

Bushnell’s Turtle Submersible

by
Side view

In 1776, during the American Revolution, inventor David Bushnell decided to take his skills to the next level and build a submarine. And not just any submarine, mind you – this one was specifically designed to attack British ships!

Now, you might be thinking, “But wait, how could a guy in the 18th century possibly build a functional submarine?” Well, let me tell you, Bushnell was no ordinary inventor. He was a genius, a visionary, and a bit of a madman.

Turtle (also called American Turtle) was the world’s first submersible vessel with a documented record of use in combat. It was built in 1775 by American David Bushnell as a means of attaching explosive charges to ships in a harbor, for use against Royal Navy vessels occupying American harbors during the American Revolutionary War. More on Wikipedia.

The submarine he built was called the Turtle, and it was shaped like, you guessed it, a turtle. It was about six feet long and three feet wide, and it had a hatch on top that could be opened and closed by the operator.

by

The SP-350 Denise, famous as the “Diving saucer” (Soucoupe plongeante), is a small submarine designed to hold two people, and is capable of exploring depths of up to 400 metres (1,300 ft). It was invented by Jacques-Yves Cousteau and engineer Jean Mollard at the French Centre for Undersea Research.[1] It was built in the year 1959 and usually operated from Cousteau’s ship, the Calypso.

Type 209-1400 Submarine

by

The Type 209 is a class of diesel-electric attack submarine developed exclusively for export by Howaldtswerke-Deutsche Werft of Germany. The original variant (Type 209/1100) was designed in the late 1960s. The class is exclusively designed for export market. Despite not being operated by the German Navy, five variants of the class (209/1100, 209/1200, 209/1300, 209/1400 and 209/1500) have been successfully exported to 13 countries, with 61 submarines being built and commissioned between 1971 and 2008.
