Can we use a railgun to launch spacecraft?
CONCLUSIONS. Yes it is possible, the tech is here, it is economic and feasible to launch anything from cargo to people. It has not gotten a lot of attention because all the big boys use rockets already, and noone has proposed a railgun that can launch more than cargo.
Are there Railguns in space?
According to Space, the electromagnetic railgun peaked at Mach 6, which means six times the speed of sound. If astronauts can station at the moon and mine resources, the said speed is just a fraction “slower” than the escape velocity. Theoretically, nonmagnetic payloads from the moon could be tossed to earth.
What propulsion is used in space?
Interplanetary vehicles mostly use chemical rockets as well, although a few have used ion thrusters and Hall-effect thrusters (two different types of electric propulsion) to great success.
How fast is a rail gun projectile?
roughly 5,400 miles per hour
To illustrate, the US Navy’s prototype railgun was able to launch its projectiles at Mach 6 – six times faster than the speed of sound. That’s roughly 5,400 miles per hour (8,690.45 kph), faster than just about any other weapon on the planet.
How fast can a railgun shoot in a vacuum?
Therefore, typical military railgun designs aim for muzzle velocities in the range of 2,000–3,500 m/s (4,500–7,800 mph; 7,200–12,600 km/h) with muzzle energies of 5–50 megajoules (MJ).
What is Rod of God?
The “rods from god” idea was a bundle of telephone-pole-size (20 feet long, 1 foot in diameter) tungsten rods, dropped from orbit, reaching a speed of up to 10 times the speed of sound. The rod itself would penetrate hundreds of feet into the Earth, destroying any potential hardened bunkers or secret underground sites.
How far can a railgun shoot in space?
The system calls for a two-mile- long rail gun that will launch a scramjet, which will then fly to 200,000 feet. The scramjet will then fire a payload into orbit and return to Earth. The process is more complex than a rocket launch, but engineers say it’s also more flexible.
How far can railguns shoot?
A railgun projectile without the ability to change course can hit fast-moving missiles at a maximum range of 30 nmi (35 mi; 56 km).
