More about railguns

Here's a BoyToy that delivered a round a zero degrees elevation seven kilometers down range after punching a hole through a 1" steel plate.

That makes the Krupp K5 railway gun "Anzio Annie" look like an archæological specimen.

Mach 5 at normal air pressure and temperatures is about 1,700 meters per second. Assuming that round has a mass of about one kilo, it would have a kinetic energy of about 1.5 million joules.

Get that round up to about Mach 34 and you have escape velocity. Plinking with that thing would involve taking pot shots at the moon...

In World War 1 the Germans had a gun that could hit Paris from 90km away.

In the Pas de Calais during WW2, they were building the V3 gun, intended to hit London over 100 miles away. The USAAF and the RAF bombed it and the Canadians got to the site before the Germans could finish the gun.

I just did a quick Google and found the "Paris Gun".

The thing was sending shells out at 1,600 meters per second (about Mach 4.7). The shells were in the air for almost three full minutes before they landed. When aiming, the gunners had to take into account the amount the Earth had rotated (Coriolis effect) during the flight time.

The maximum altitude it was capable of achieving was 40 kilometers (131,000 feet).

The article claims the maximum range for a 94 kilogram shell was about 130 kilometers. The gun was never captured and was completely destroyed by the Germans towards the end of WWI, along with the design plans.

Wow....

Penis envy?

God, I hope not...ejaculation would be a little more than a woman could handle.

What is impressive (did I say that?) is the fact that while a modern high tech rail gun can fire a projectile at 1600 meters per second, the Germans were doing that almost a century ago using good old gunpowder. And their projectiles weighed in at 94 kilos. It was a destructive and deadly weapon of war, yes, but the engineering is impressive. The noise, flame and air shock that must have accompanied that thing going off would have been awesome.

It could be heard in London.

Causing the Artillery Corps to suffer so called , "Redleg's Disease", due to the red stripe on (American) Artillerymen's uniform , circa 1840-? 1898.

Rail guns may be fast but they don't remove the house with the shell.

Are you kidding? The kinetic impact of even a solid shot would be enough to blast the target to smithereens. Look what happens when a good sized meteorite hits. It's elementary physics, F=MV

Linky no worky?

 

[voluptuary_manque]

This one does.

...uhh...when I was in high school, it was F=Ma...force equals mass times acceleration...and kinetic energy was K=1/2 M(V squared)...

No, Stephen, Father does NOT equal Mater. You're a Doctor; you should know that!

And, I'm afraid Farce does equal Men by Velocipedes.

Q.E.D.
