Something to Ponder II
« on: Fri Aug, 25, 2017, 04:54:PM »

I need to start second thread for this nonsense since it is becoming impossible to add or reply to the original thread .
Evidently SMA is loading the entire cache of the original when I try to add to it and it's getting bogged down or completely derailed .  Ooops


In response to John about the rail-gun vid :

 ;D  Yeah   -  that thing accelerates that 45# projectile from zero to 5000 mph in 1/100 th of a second   :o
       I assume that big plume of smoke is from material being burned off either the projectile or the rail .
       need to find out

With the rail gun nothing should be touching those rails that's kind of the whole point to it .

It's a completely reusable system and only thing you have to load into it are projectiles

The material coming out is the casing for the projectile it kind of blows apart by that acceleration also the use of pretty Blunt nose projectile and allowed the air resistance to shape the project out the proper shape as it travels through the air

What is the casing for the projectile made of ?
Something is burning  - or vaporizing .

I am sure it is something to protect the projectile.   Think about the amount of energy they are dumping to fire that projectile at that speed.   It is something that ablates, kind of like the heat shield on the old apollo space craft.
