Vortex block question

Unread postAuthor: The Hellforger » Mon Nov 07, 2011 8:12 pm

Has anyone figured out the perfect ratio for a vortex block?

i mean if the ammo is X in diameter, then the block should have an inner circumference of Y?

What ammo did you have in mind?

right now we were looking at airsoft pellets but then the question of could we do it with paintballs came up.

i was just seeing if there was a general ratio or if it was really ammunition specific

Paintballs wouldn't work, they'd probably break. I'm not sure about a ratio...

yeah that was a thought i had because i know vortex blocks are pretty violent on the inside

I've made a pretty decent cloud with .40 cal paintballs, I'm sure it could be done with .68 cal balls too

Those powder type paintballs seem pretty tough.

Re vortex hole diameter, it should be close to 1.5, 2.5, 3.5 etc times the diameter of the ammunition to avoid jams.

I did a little rough estimation in my head and I'm thinking a 3.5" hole would be good for a 3/4" cpvc barrel?

If this is for paintball and the inner diameter of the barrel is 0.69", this would make the hole almost exactly 5 times larger than the paintballs, which invites jams. A 3" hole in this case is a better idea.

Ok, that sounds fair enough for me. I was just going off a rudimentary scaling up of someone's6mm barrel with a 3cm block. 6mm goes into 3cm 5 times and almost .7" goes into 3.5" 5 times. But I will try the 3 out if I ever get a chance because theoretically that will reduce jams as you said and should improve efficiency. We were also discussing bending the 3/4" cpvc in a manner similar to tippmann's flatline barrel to get a huge boost in range

Granted they have drawbacks but they have advantages too. And I mean this was an idea for a strafer and not a precision marker for lack of a better term. In terms of size this thing would probably have to be crew served if not stationary or vehicle mounted

My point is that curving the barrel upwards isn't really going to give you a "huge boost in range" - you might as well aim slightly higher.

There's a reason why this thing was used for shooting round corners as opposed to hitting targets 5,000 yards away ;)

well now your just splitting hairs lol.

it may not be a huge boost but is it not true that a small boost is better than no boost at all?

You'd be better served aiming up. Curving the barrel will increase friction, causing a decrease in velocity. In paintball systems such at the Tippmann Flatline or the Apex barrel system, the paintball has spin imparted to it not by a curve in the barrel, but by striking the round gently against a tacky rubber surface. The amount of spin imparted is changed by adjusting how far the bumper protrudes, thus changing how hard the projectile strikes it. In order to compensate for that, I have to slightly increase the output of my gun.

Extra range isn't a part of the benefit of either system, really, but rather a flatter trajectory. Or in the case of an Apex, a severely curved trajectory, useful for nailing people crouched behind berms. So unless your goal is to get a flatter trajectory from a spherical projectile, you should really just aim up.
