Hi all,
I want to know in detail about gun, especially the properties of gas with hight pressure like in gun's barrel. Could you give me some free useful things?
Or just answer me some question:
1 When firing, from the beginning of the explosion until the bullet leaves the barrel, how pressure of gas is changing?
2 How gas does when meet another low pressure way, like a tube leading the gas back in automatic assault rilfe? Is the pressure contact the bullet still the same as in case there isn't any tube leading gas back? And how is pressure in that tube, equal the barrel or not? I think when meets low pressure way like this, at first, gas will transmit almost all it's pressure to that way until two ways have the same pressure, right?
3 And how fast does gas changing it direction when meet another way? I remember that gas's pressure transmit in all direction, so when meet another ways, it immediately change direction with full pressure, correctly? And when in hight pressure and very fast process like this, is it still considered immediately, in comparison with the movement of the bullet?
