What is the scale of this thing ? What sort of projectile?
To deliver a payload 200miles away without liquid propulsion will be taking warfare to the next level and you can imagine how quickly the technology will improve. In fact this could potentially have a massive impact on military superiority, it could eventually almost level the playing field if you take nukes out of the equation.
How it go level playing field if is US patent military hardware....it moves the us years further than they already are..dais all. Level the enemy yuh mean?? covered by ITAR rules, no way that technology getting to anyone else in a hurry, and when it does rech dem the US done improve and move on to something else..doh get tied up
Leh meh explain how this shit works in easy to understand parlance fuh yuh:
In railgun physics, the magnitude of the force vector can be determined from a form of the Biot–Savart law and a result of the Lorentz force. It can be derived mathematically in terms of the permeability constant (μ0), the radius of the rails (which are assumed to be circular in cross section) (r), the distance between the centerpoints of the rails (d) and the current in amps through the system (I) as follows:
It can be shown from the Biot-Savart law that the magnetic field at a given distance (s) from a semi-infinite current-carrying wire is given by:
So, in the space between two semi-infinite wires separated by a distance, d, the magnitude of the field is:
To obtain the average magnetic field in the space between the two wires, we assume that r is small compared with d and compute the following integral:
By the Lorentz force law, the magnetic force on a current-carrying wire is given by IdB, so since the width of the conductive projectile is d, we have
The formula is based on the assumption that the distance (l) between the point where the force (F) is measured and the beginning of the rails is greater than the separation of the rails (d) by a factor of about 3 or 4 (l > 3d). Some other simplifying assumptions have also been made; to describe the force more accurately, the geometry of the rails and the projectile must be considered.
