Evolving the human fascination of throwing things over bulky distances, electromagnetic launchers (EMLs) provide the next step in rocket engine technology. With two different functional designs that utilize magnetic and/or electric fields, both(prenominal) presently more(prenominal) effective (regarding doable projectile velocities) than conventional combustion-driven firearms.
The two effective methods for linearly accelerating a particle deal primarily with maximizing the potential of the Lorentz campaign, and the storm of attraction between two objects with magnetic fields. First, the Lorentz force is the madcap force in the technological development of rail guns. In a c formerlyptually counter-intuitive fashion, magnetic fields oriented impudent to current carrying wires, instigates an acceleration of the conducting bar that spans the two rails, as figure in in the diagram below:
The way this force operates is by the cross-product relation of Current and Magnetic field, following the kinship: F=(current)*(length)x(B-field). This force ensures that the bar will continue to be accelerated as long as current is spillage through the bar from one rail to the other, adding energy along the entire path of the barrel.
This design improves on traditional firearms, which only have an initial acceleration of the expanding gunpowder to instigate the projectile.
The alternate design that creates this same result is the coil-gun method. This system utilizes a linear arrangement of one or more concentric coils that draw a projectile ferromagnetic material towards the coil. If more than one coil is used, poly-phase sequencing of the coils must be established, so once the projectile has passed through a coil, it must shut take away to not pull the projectile backwards, decelerating it along its path. A simplistic example of the set up is shown below:
The implications of the coil-gun transcend both traditional firearms, as well as rail guns, notwithstanding being in...If you want to get a full essay, shape it on our website: Ordercustompaper.com
