Have some neighbors that are giving us problems, are we?Yup, saw that on Discovery channel 2 weeks ago, I want one
Speed of the projectile might catch the oxygen on fire if its that pressurized. Think about the friction of an object going 6000mph just in the air. Look at the space shuttle, that gets glowing hot in space. Not that thats the answer but I'm sure its something like that. Read the comments and I'm sure some nerd knows.Rail gun? Looked explosive based to me. Why all the fire out of the barrel?
ha ha ha, right on target BillHave some neighbors that are giving us problems, are we?
Yes, the main limitation of supercaps is that they are low voltage devices. There may also be some dynamic issues with very short pulse times, but I'm not sure about that. However, they can provide hundreds of amps of current in short bursts.There are super caps, but they tend to be limited at this time.
Ok. But something doesn't make sense.Actually it is the plasma caused by both the intense magnetic fields and some electrical discharge. It would burn you just like power, if not worse. I is much hotter I believe.
Anytime you pack enough energy in a small space, there will be plasma. Fire is a type of plasma, this is electrical discharge plasma.
plasma actually forms best in a low pressure environment, look at farnsworth fusorsOk. But something doesn't make sense.
If the projectile is truly hypersonic, there should be a nearly perfect vacuum on the trailing edge of the projectile. No air, no plasma, no fire. Additionally, there should be plasma evident on the leading edge due to ultra-high gas compression.
Perhaps the 'plasma' temperature on the trailing edge is hot enough that its local speed of sound exceeds that of the projectile (speed of sound in air ~330m/s + 0.5 m/s/°C), thereby negating a vacuum, but that still doesn't explain the lack of plasma on the leading edge, especially since this is purposefully a 'non-aerodynamic' projectile.
FYI, I've never seen before a hypersonic projectile, so I am basically pulling this out of my butt. But it didn't meet expectations...
One thing that is *really* neat about the video is you can clearly see the change in the index of refraction of air due to compression (and/or heating) as the projectile passes through it.
Well every explosion forms a vacuum and implosion. Just look at the old Vietnam bomb videos of the wind blowing all the trees out, then sucks them back in real quick.plasma actually forms best in a low pressure environment, look at farnsworth fusors

I read somewhere that this shockwave is actually what causes the most casualties in an explosion like that. I guess the force hits you so hard it damages your internal organs. Like when people die from getting shot with a shotgun even though the slug or pellets didn't hit anything vital. The brute force of the shotgun shell hitting the body destroys the internal organs.yep
the explosion and massive release of energy pushes all the air away, then suddenly the explosion is over and it all rushes back in
