Demonstration of the Navy Electromagnetic Rail Gun prototype

Back


The US Navy's Electromagnetic Rail Gun that is under development at NSWC Dahlgren in Virginia. This is a prototype to demonstrate the technology of the rail gun for use on the future DDG-1000 class of Navy ships. This clip is from the show FutureWeapons on the Discovery Channel. It aired in April 2007.

these is why we hold one of the worlds strongest army in the world

People who build things like that shoud all die and burn in hell...

Humans are sick....

Right, the maximum force is lower, but the average force is the same. Conservation of momentum.

Exactly, the kick is from the acceleration of the bullet, a railgun doesn't fire with old fashion gunpowder.

this thing is a beast

The kick, is due to the acceleration of the bullet. Sort of like crashing your car. The kick you get that propels you towards the front window, is due to your car rapidly slowing down. Same with a rifle.

No, by recoil i mean the kick u get from i.e shooting a rifle.

By recoil, what you're thinking of is the acceleration. In this rail gun, the bullet accelerates very slowly compared to a regular howitzer because it can accelerate over the entire length of the barrel. It's sort of like, I floor the accelerator in my car for a short amount of time and the engine will push really hard, or I can lightly step on it for a longer time and the engine will push just a little. But in both cases, I will end up at the same speed. The average force is the same in both.

It's still a lot less recoil than a regular howitzer or rocket launching pad.

Yes you do! Imagine being in space where there is no friction, and you throw a ball. That would cause you to move very slowly in the opposite direction of the ball. In fact, this is how rockets move in space. They burn fuel which gives off fumes. These fumes are pushed out of the bottom of the rocket at very high speeds. That's what pushes the rocket forward. That's pretty amazing; throwing air for propulsion!
