Secret Inventions Of Leonardo Da Vinci

The first diving suit, the first machine gun, the first prototype of an aircraft. All this was created by one man 500 years ago. One single man. Leonardo da Vinci was the most renowned Renaissance man who created tons of masterpieces in art and inventions. But did you know he also created weapons? Some of da Vinci's designs even made their way to NASA. It's an interesting story and we'll talk about it later. But now let's focus on the weapons. Da Vinci hated violence and he preferred to focus on creating beauty in art for the benefit of mankind. But during the Renaissance much of Italy was in conflict and da Vinci was required to appease his wealthy patrons who were part of the struggle for One of those patrons, Cesare Borgia, commissioned da Vinci to design weapons and military machines for both defensive and offensive purposes. One of da Vinci's weapon inventions was a triple-barreled cannon, which was a forerunner of the modern machine gun. Cannons were very heavy and cumbersome to move and aim. They were also slow to reload. Da Vinci designed a triple-barrel cannon to be a lighter piece of artillery that could be moved and positioned on the battlefield as it was wheeled around on a wooden cart. It was designed to be able to shoot three shots at once or one shot at a time, allowing reloading while one was being fired for a continuous flow of firepower. Another weapon da Vinci invented was a giant crossbow known as a ballista. Instead of firing arrows, this enormous 80 feet wide crossbow would throw large stones or flaming bombs. A different type of war machine conceived by da Vinci was the precursor to the armored tank. A circular platform was covered with metal plates. Its position could be adjusted to aim mounted cannons in any direction or to protect itself from enemy fire. It was propelled by wheels that moved by men inside the vehicle turning crankshafts. However, the mechanics of the design were flawed in da Vinci's drawing. If the machine was built as drawn, the wheels would move in opposite directions and the vehicle would never move forward. It has been suggested by scholars that this was an intentional flaw. Da Vinci may have deliberately drawn a design error in the tank design, specifically to prevent it from being put into use since he detested weapons of war. In his lifetime, da Vinci created many drawings related to flight and wrote journal entries about flying. His visuals consisted of both bird and human flight, and his desire to fly is evident in many different designs for wings. It is believed that a hawk once hovered over his cradle when he was a child, and when recalling this incident, da Vinci saw it as a prophetic moment. When he began to study birds in flight, da Vinci realized that their ability to fly was related to their light weight. He concluded that humans would be too heavy to fly with wings, as their arms would not be strong enough to lift and propel them. He had a vision for a flying machine that could keep a man in the air by beating artificial wings, assisted by a mechanism with levers, pedals, and pulleys. His flying machine schematic drawing shows a giant pair of wings connected to a wooden frame. The pilot would lie face down in the frame on a flat board, inserting his feet into stirrups. Then the pilot would grip a stick coming from each wing for direction control, and would make a flapping motion by pushing his legs down. The system that da Vinci created would enhance the human's own physical power to create enough force for liftoff in flight, but it was actually unlikely that such a design would have ever gotten off the ground. And if it did, it may have not flown far, nor would it have landed in one piece. In fact, legend has it that he tested this machine on one of his apprentices, who fell and broke his leg. He also developed one version that was powered by a rotor. He also designed a parachute, a crude early concept for a helicopter, and a light hang glider, which was likely to have actually flown. Even though none of da Vinci's flying machines actually took flight, his ideas were significantly ahead of their time, and some of the designs we see today can be traced back to ideas attributed to da Vinci. Da Vinci had been living and working in Milan for almost 20 years before he escaped the conflict there and moved to Venice. He was inspired by his new environment in Venice, being surrounded by water. He spent long days studying the water, its properties, tides, and the movement and power of waves. It was here that he was inspired to draw a sketch for a diving suit. The head was covered by a helmet with two eyeglasses in front. There was a breathing tube constructed of bamboo and connected to the back of the helmet by joints created from pigskin. The helmet connected to a float made of cork and wood, which would have acted as a compressed air chamber when submerged. While living in Venice, da Vinci was experiencing more conflict as the floating city was constantly being attacked by the Ottoman Empire. It was believed that these ideas for diving suits were born from the concept of defense. Diving suits would enable sneak underwater attacks against enemy ships entering Venetian waters. Soldiers could submerge and slash holes in the hulls of approaching enemy's boats. There is no record that these diving suits were ever built, however, and da Vinci didn't divulge all the details of the design for fear it would be abused or be used for the evil nature of men. It is well known that one of da Vinci's areas of extensive study was anatomical research. He studied the human form in great detail. He learned about muscles and joints and how the body moved and functioned. He even dissected cadavers and examined their interiors to further his knowledge. Back in 1495, da Vinci had conceived an idea for a mechanical knight, which in essence, is a robot. When he designed the mechanical knight, he had human anatomy in mind. The knight had proportionate limbs, joints, and da Vinci designed the mechanics of the robot to move in a way that imitates the way human muscles move. The robot could move its arms, raise its sword, move its jaw and neck. It could even sit, stand, lie down, and walk a few steps. The entire robotic system was operated by an elaborate series of pulleys, cables, gears, and wheels fitted into the robot's chest. This mechanical knight was very advanced for its time. In fact, we can even say that it was the very first robot in the world. In 2002, roboticist Mark Rauscheim followed da Vinci's drawings to build a prototype of the mechanical knight. Using the drawings as blueprints, Rauscheim easily constructed the robot, and it functioned as originally designed. Rauscheim even used da Vinci's designs as inspirations for robots he later developed for NASA. Shortly after da Vinci's original mechanical knight made its debut at a pageant in Milan, da Vinci was commissioned to utilize his engineering skills to design another automaton for a gift for King Louis XII. He designed a mechanical lion that, like the knight, was capable of movement. The life-size lion was designed to walk up onto a stage and offer flowers in honor of the French king. Unfortunately, the mechanical knight and were lost or destroyed at some point in history, and the robot drawings also remain lost to us. The Renaissance is known to be an era of significant progress in art and architecture, but it's rarely acknowledged that the 15th century also marked the birth of urban development and city infrastructure. Da Vinci put his mind to rethinking the archaic and dysfunctional design of medieval cities, with their winding, narrow, overcrowded streets lined with houses piled on top of each other. Da Vinci's vision was for a modern city, spacious with efficient streets and magnificent but functional architecture. He recommended high, strong walls with necessary but beautiful towers and battlements. His plans for a modern city called for the city to be built on several levels, linked with vertical staircases. Da Vinci's concept was for upper levels of the city to be primarily for residential housing, and the lower levels would be for services, trades, transport, and business. But the true genius of Da Vinci's vision was its sophisticated infrastructure. He created designs for hydraulic plants to create artificial canals for boats to navigate inland and transport goods. He suggested that the width of the streets matched the height of the average buildings, to allow sun access and to reduce the risk of damage from earthquakes. This rule of thumb is still in practice in many contemporary cities across Italy. Da Vinci's idea for a compact city built vertically instead of outwards, with efficient water systems and transportation, was like many of his concepts and inventions, centuries ahead of his time.
