CATIA CAD on the 3DEXPERIENCE platform helped recreate Leonardo da Vinci's warship
Many engineering engineers are inspired by the talent of Leonardo da Vinci - the “universal man” who successfully combined art, science and engineering, anatomy and medicine in his work.
Today, his work can be seen in such famous museums as the Louvre in Paris and the Uffizi Gallery in Florence. They were the ones who prompted Alain Dugusse, PLM CATIA V5 / V6 expert at Dassault Systèmes, to take part in the 3D Open Codex 3DEXPERIENCE Lab project dedicated to the virtual re-creation of Leonardo’s inventions.
Among the many sketches from the heritage of the master (flying machine, tank, parachute, helicopter, etc.) in the Italian archive of Piazza della Scala, Dugussé discovered something curious: a top view and several types of structure nodes, very similar to a warship.

However, these species do not give a definitive idea of how da Vinci saw the realization of his creation. To visualize the ship in 3D, it was decided to combine the sketches found with the sketches of a similar model of the tank.
Let us tell in brief about this project, which was carried out in CATIA and 3DEXCITE software products on the Dassault Systèmes 3DEXPERIENCE platform.
Concept. The first sensation from the top view was that this is a prototype of a modern tank - but if you look closely at the central part, you can see the wheels with blades, that is, probably Leonardo da Vinci conceived the design as a means of transportation through water. The 16 guns on board clearly confirmed that the ship was designed as a combat one.
Battery Deck. The idea of da Vinci, as follows from the top view, was to place 16 artillery pieces around the perimeter of the deck, and in the center a rowing rig.
16 guns. Guided by what is depicted on one of the ship's cuts, Dugussé placed combat guns on V-shaped supports.
Rowing installation. A careful study of the top view showed that the installation includes:
It is clearly seen that the total arms are not 2, but as many as 5:
Motion control system. Reflecting on what the fifth handle was intended for, Dugussé looked at several other sketches by Leonardo da Vinci, and at last he had an idea that could later be verified using the 3DEXPERIENCE platform. The expert suggested that it rotates the entire rowing installation around the vertical axis of the ship, and thus allows it to change the direction of motion.
Theoretically, the direction of movement could be controlled in a different way, namely, by placing the paddle wheels on separate axles. But in practice it is inappropriate for the following reasons:
3D. After the battery deck was modeled, the next step was to build a bulk model. Since da Vinci in the model of the tank also had guns evenly around the circumference, Dugusse built a virtual ship in 3D in the same way.
3D-visualization of the ship of Leonardo da Vinci in a real situation.
Using the 3DEXPERIENCE platform and new 3DEXCITE solution capabilities , Dugussé performed a realistic visualization of a 3D model of a ship on a water surface.
From Leonardo's ideas to modern ships. In order to make the picture more intense and emphasize historical contrasts, Dugusse at the final stage added several more modern ships to it:
Without a doubt, many will be curious to compare the ideas of Da Vinci, on the basis of the sketches of which we have created a digital 3D layout, and what the shipbuilding industry is producing today.
Well, as time goes by, technology evolves!
For a more detailed acquaintance with the CATIA functionality, we offer you to look at a webinar containing an excerpt of materials about the main improvements and innovations in 3DEXPERIENCE CATIA 2019 . In this review, information about new applications is announced, a number of improvements are considered. The review contains advanced designs and tooling proposals for designers, designers and system architects.

16 guns. Guided by what is depicted on one of the ship's cuts, Dugussé placed combat guns on V-shaped supports.
Rowing installation. A careful study of the top view showed that the installation includes:
- two main paddle wheels with blades located on a common axis;
- one auxiliary wheel with two handles (on the same axis), giving the initial rotation of the main wheels.
It is clearly seen that the total arms are not 2, but as many as 5:
- 2 on the main axis for rotating the main wheels;
- 2 to rotate the start wheel;
- and another, whose purpose at first was not entirely clear.
Motion control system. Reflecting on what the fifth handle was intended for, Dugussé looked at several other sketches by Leonardo da Vinci, and at last he had an idea that could later be verified using the 3DEXPERIENCE platform. The expert suggested that it rotates the entire rowing installation around the vertical axis of the ship, and thus allows it to change the direction of motion.
Theoretically, the direction of movement could be controlled in a different way, namely, by placing the paddle wheels on separate axles. But in practice it is inappropriate for the following reasons:
- even a small difference in the speeds of rotation of the propeller wheels deflects the ship from the rectilinear path;
- the launch wheel on the sketch is only one, and it is not clear how, in this configuration, to report the initial movement to another paddle wheel.
3D. After the battery deck was modeled, the next step was to build a bulk model. Since da Vinci in the model of the tank also had guns evenly around the circumference, Dugusse built a virtual ship in 3D in the same way.

From Leonardo's ideas to modern ships. In order to make the picture more intense and emphasize historical contrasts, Dugusse at the final stage added several more modern ships to it:
- the multi-purpose frigate “Aquitaine” of the French Navy (still in service);
- battleship "New Jersey" US Navy (in the fleet from 1942 to 1991);
- the battleship Bismarck of the German Navy (launched in 1939, sunk in 1941);
- the battleship Yamato of the Imperial Navy of Japan (launched in 1940, sunk in 1945) is one of the largest and most well-armed warships in history.
Without a doubt, many will be curious to compare the ideas of Da Vinci, on the basis of the sketches of which we have created a digital 3D layout, and what the shipbuilding industry is producing today.
