Da Vinci Catapult Models

Leonardo da Vinci catapult models are both simple and ingenious. The mechanical catapult involves a pawl and rachet system which incrementally tightens the firing system. As the system is tightened, the forces put into the system by the operator (1 soldier) are transferred to both the ropes and tension arms of the catapult. For catapult locking mechanism, on releasing the firing pin (the pawl), the stored energy is instantly transferred from the ropes and tensioning arms to the swing arm which would contain a lead ball/cannonball.

What does a catapult look like – this machine looks like it could have been operated by a handful of soldiers: four or five soldiers for moving/repositioning/aiming the catapult and 2 men for operating the machine – one to tighten the mechanism and one to release the firing pin.

Interesting facts about catapults – this machine would undoubtedly have wrought havoc upon any castle/fort it attacked. It could be reloaded and retightened very quickly. For catapult firing, as with all medieval catapults, the soldiers may have decided to fire flaming ballistics or even disease-ridden dead bodies into the castle they were attacking – this usually spread either fire or disease very quickly within the walls of the target castle/fort. Within a castle that is under sustained attack, water supplies quickly begin to dwindle and the population begin to grow weak due to lack of food, thereby decreasing their odds of putting out any flames and increasing their odd of succumbing to illness from disease-ridden bodies flung over the walls.

Who invented the catapult – catapults were used in the early 4th century BC. which was invented by Greek Diodorus Siculus in 399 BC as part of the equipment of the Greek army.

Leonardo mirror grinder

 

Leonardo da Vinci was not only an artist, but also an engineer who designed and built various machines. One of his lesser-known inventions was a mirror grinding machine, which was designed to produce parabolic mirrors for use in optical devices such as telescopes. Leonardo’s design was based on the principles of physics and geometry, and demonstrated his mastery of the scientific and mathematical knowledge of his time.

The mirror grinding machine that Leonardo designed was an innovative and efficient mechanism for producing high-quality optical surfaces. It was based on the use of a rotating tool that was driven by a series of gears, which allowed for precise control over the grinding process. Leonardo’s design was also able to produce mirrors with a high degree of accuracy, which was essential for the production of telescopes and other optical devices.

Despite the significance of Leonardo’s mirror grinding machine, it was never built during his lifetime. However, his designs and drawings provide a valuable insight into the innovative and visionary thinking of this great Renaissance genius. Today, Leonardo’s mirror grinding machine continues to inspire engineers and scientists, and serves as a testament to his contribution to the fields of engineering and optics.

Devices like these are still used nowadays by amateur telescope/optical instrument makers around the world. The version they use is a tabletop sized mechanism, but is essential of the same design as Leonardo da Vinci mirror grinding kit, the only difference being the use of an electric motor instead of the hand crank.

Leonardo da Vinci Crossbow

 

Leonardo da Vinci Crossbow ranks among one of his most scary war machine inventions. Can you imagine seeing this beast aiming for you from several hundred meters away?

Leonardo da Vinci’s crossbow machines

 

The crossbow is also referred to as his Ballista. The machine was coiled or cocked using a worm gear (which he also designed), this enabled a huge mechanical advantage and allowed two men to fully draw back the huge bows of the crossbow.

Once cocked the machine could be fired by either hitting a release catch with a hammer or pulling on the catch with a rope, both mechanisms were designed by Leonardo for the firing of the crossbow. We would imagine the rope would have been preferred by anyone that may have operated such a huge weapon. Both of the release mechanisms can be seen to the left of the crossbow design above.

 

Construction of the Crossbow

The bow was to be made of several interlocking sheets of wood in a kind of forerunner of lamination, this would allow for flexibility during the cocking of the bow and also increase the spring during its release. It could be loaded with many different types of artillery as it seems to have a kind of cradle, in which almost anything imaginable could be used, possibly even the cluster bombs that Leonardo, a crossbow inventor, also invented.

 

Recreation of Leonardo’s Crossbow

Leonardo da Vinci giant crossbow was recreated based on his original drawings by a team of engineers. The only modification the team had to make was to create a second bow as the first one snapped under the immense strain as the bow was ratcheted up to full tension.

In modern times machines like this have been made obsolete with the improvements in artillery, some of which can go up into space and land on another continent thousands of miles away.

Model Of Leonardo’s Glider

Here at LeonardoDaVincisInventions.com we have created a hanging model of Leonardo’s Glider. This model is a combination of all of Leonardo’s attempts to build a flying machine blended into one beautiful decorative piece. The model is just under two feet wide and casts beautiful shadows when hung (safely) below a light source and is available for an unbelievable low price of just 33USD/24 Euro, click on any of the images to order your own model of Leonardo’s Glider.

Hanging Model of Leonardo’s glider

We took the main inspiration for the model from his drawings of the Kite wing –

The wing can  be seen in the upper left portion of the drawing. We “traced” over the original drawing in order to get the two dimensional profile of the model. From that, we used some of Leonardo’s other drawings to create the full 3d profile of the model, taking aerodynamics into account also. All you need is 3 lengths of string to hang this piece from anywhere within your home or workplace –
