The Mk. V version of the spitfire was introduced with the Royal Air force in 1941 in order to replace the preceding Mk. I, the backbone of the battle of Britain. This model was extensively used on all theatres until the end of the war despite the appearance of more modern aircraft. Its manoeuvrability and sturdiness made it possible to oppose successfully most enemy aircraft. This Spitfire version employed in North Africa was characterized by various anti-sand filters used for the main air intake in order to operate from improvised desert airfields.
Together with its British counterpart, the Spitfire, this was the best known aircraft of World War II. The BF version was distributed to German units around the spring of 1942. It is considered to be the best version of this small fighter plane, despite considerable structural and engine problems in the beginning.With this aircraft quite a number of German aces won their battles in the air. Various types of Bf-109 F were built such as ground attack fighters, anti-ship versions and reconnaissance planes.
The Mustang is one of the worlds best known airplanes and was without doubt the best fighter plane of World War II. It was built in record time in 1943 for the European campaign and was well suited to fight the BF-109s and FW-190s of the German Luftwaffe
The catapult was a medieval weapon which Leonardo reworked and improved upon. As shown in the drawings on page 140a/br of the Atlantic Code, which represent six designs of a spoon-shaped catapult, the loading mechanism is activated by two large flexible wooden arms that increase launching power. The stone or metal projectile is placed in the spoon-shaped end of a long lever. The loading operation turns the large central pin and flexes the curved wooden arm. The safety catch is then released to launch the projectile straight at the target. The launching power is proportional to the length of the lever arm and so the energy involved in throwing the projectile is high, allowing the projectile to cover particularly long distances.

That genius of Leonardo Da Vinci doesn't need any presentation. All his inventions and ideas written by him in the Atlantic Code were in many senses forefront. Many of these, that today we take for granted, are based on its thoughts and visions. Regarding the clock, Leonardo da Vinci wasn't the inventor, he only improved it. The clock have two separated mechanism: one for the hours and the other for the minutes, everyone made by an elaborated connection between weights, gears and ropes.
On page 945/r/ of the Codex Atlanticus, Leonardo da Vinci drew many devices for the plan of a mechanical paddle boat. One or more sailors can alternate working the pedals. The pedals transfer the alternate motion to a central gear, where it becomes linear motion, and a series of gears transfer it to the two big paddles on the sides of the craft. The central gear is drawn in more accurately on another page, 30/v/, and the mechanism works through springs hidden in the two main wheels that alternate
Sheets 90/v and 91/r of the Madrid Code include drawings of strange mechanisms that are not linked to the treatise on mechanics and often have no explanatory text. Analysing them led to the reconstruction of mechanisms enabling a mysterious animal, a mechanical lion, to move robotically. The lion, a gift from Pope Leone X and the town of Florence, was taken to Lyon, in France; on July 12 1515, at the end of a surprising, magical walk before the King of France, Francis I, it stopped knocking some lilies over. It can be considered one of the first animal-like robots ever built.
This model represents one of Leonardo da Vinci's most intriguing designs. It has been known as "Leonardo's Automobile" but recent studies consider it one of the first robots in history. The machine is drawn on folio 812/r/ of the Codex Atlanticus together with other devices. The robot's engine is hidden internally: a spring held fast by a stopping mechanism trasmits motion to the gears that move the wheels on the sides.
The Apache is certainly the most powerful and sophisticated combat helicopter thanks to its robust fuselage, which was designed without saving costs, as well as remarkable electronic equipment and massive weapons systems. Presently modifications are carried out to adapt the D model equipped with Longbow radar. This allows more efficiency in using anti-tank missiles and greater capacity to direct its fire-power.
