Reply To: Velocity
An easy way to think about what happens is a boat on plain with the wave front running behind the boat, as the boat slows the wave catches up and slews the boat.
I think that there are multiple hurdles that stop airguns from shooting at higher speeds
1. (Most likely the biggest ) BreadNButter If airguns started being able to shoot at speeds comparable to powder burners more state and fed restrictions would soon follow. Manufacturers don’t want that to happen (neither does most air gunners)
2. Compression issues. This part is over my head but you are moving air from one chamber through a valve into another chamber where expansion and escape happens, It does not matter what material is involved gas liquid or solid a sudden expansion will result in heat. And any valves or orifice that the gas passes through would erode and wear out.
