The objective of this project was to design and build a model gun Electrical often called Rail gun . This object propels a projectile conductive metal through the Lorentz force. It consists of an electric charger, capacitor bank and gun itself. It had to be done at the beginning of a phase of documentation to learn, especially on the Internet about other gun s previously made, which is reflected in the first part of this document. From there emerged the main difficulties we would surely face. It was followed by a phase of theoretical modeling using Maple to size gun and components.
[...] It turned out that he had actually quadruple the power they were able to collect global Mounting the charger 264V 400V 220V Max Min-264V Fig 31 Diagram of the charger Doubler Latour is preceded by an input resistor with a value of 100 Ohms and 25 Watts. It lowers the input to a value less than 2A current to protect the constituent components doubler Latour. These ingredients are: two 400V and 3A diodes, two capacitors 100?F and 400V. [...]
[...] This object propels a bullet of conductive metal thanks to Laplace strength. It Consists in a power adapter, a bank of capacitors and the cannon Itself. Firstly, It was Necessary to gather documentation so as to inquire on the Internet about other railguns calculated previously Realized All which reports to the first portion of this document. Stood out from there the hand we probably Difficulties Would Have to face. There Was a period of theoretical designing using Maple to size the cannon and the components we HAD to buy. [...]

[...] From there emerged the main difficulties we would surely face. It was followed by a phase of theoretical modeling using Maple to size gun and components needed to buy. Will be detailed more specifically in the following discharge of the capacitor bank, the establishment of the induced current flowing in the rails and the movement field of the projectile in the barrel itself. The next step was to draw up the plans of the barrel. [...]
[...] It took a long time and asked some precision in the assembly of components. All this was done under strict security restrictions designed to protect the equipment and especially the people, given the high currents involved during a shot of the prototype. Keywords: Electric Canon, Rail gun, Lorentz force, Laplace rails, prototype, Electromagnetism, voltage doubler, capacitor bank. Summary The objective of the project WAS to design and build an electric cannon, Also called Railgun. [...]
