It's a Wiesel with a (recoilless) 30mm revolver cannon! Awesome!

[TheRingmaster]

That's awesome, if they want to model it. They already have a modeled version with a 25mm autocannon, so it's probably unlikely that they would include this version. This still kicks ass regardless, and if they did decide on including it I sure as ###### would not be complaining.

[Furiou$ Mental]

Did they? It's still pretty awesome

What the ###### is a recoilless cannon?

[-=AMI=- Drenelin]

Just looking back at vestalis' thread - have you guys actually coded the weisel in-game yet? Just there are only renders - no in-game screenshots. Will understand if you are keep quiet about it for a reason

Seriously? It is sort of self explaining: A cannon with no recoil. Open in both ends.
Not quite sure how it functions on a 30mm cannon though, but seeing as this is a 'revolver operated' weapon, I imagine the cartidges are held in a revolver, that is open in the back, and rotates after each shot, placing a new in the firing position. I suppose the casing are thrown backwards as they are beeing shot.

I know on the other hand, that on various RCLs (Recoilless Rifles, that is) e.g. the 84mm Carl Gustaf, the casing it self is just a hollow metal sylinder, with the sole purpose of holding the grenade in place when in the weapon, prior to firing. When you open the breach after firing, the casing falls out.

Are 30mm ammo for this recoilless cannon just like a scaled down version of the ammo used in e.g. the Carl Gustaf? Or is it using standard 30x173mm NATO ammunition?

[RedAero]

If the cannon were open on both ends it would not fire
What propels the bullet through the barrel is the pressure behind it. The Carl Gustaf works because the projectile has it's own motor inside, also known as an RPG(Rocket Propelled Grenade). 30mm projectiles are not rockets.

"What propels the bullet through the barrel is the pressure behind it. The Carl Gustaf works because the projectile has it's own motor inside, also known as an RPG(Rocket Propelled Grenade). 30mm projectiles are not rockets."

Rofl. You're right, 30mm cannon shells are not rockets but that makes absolutely no difference. In the case of both a cannon shell and a rocket propellant gases are generated which impart kinetic energy to the projectile. You allude to the fact that a rocket motor can propel a rocket simply by pushing against air, can you explain why a cannon shell, which fundamentally works on an identical principle, cannot do the same? The simple fact is that it can do the same, and that has been well and truly proven for decades. Have you never heard of a recoilless rifle? Apparently you have, but you don't seem to realise it. Yes, as Denver points out, the Carl Gustav is in fact a recoilless rifle, not a rocket launcher.

As far as ammunition goes, it's 30mm x 230mm as I understand.

I may be wrong, but I think in this case the casing doesn't provide a solid "backstop" to the propellant gasses, IIRC it allows a portion of the expanding gas to escape to the rear. This would explain why it must use a revolver type action, if there's little or no back force on the casing itself, the weapon must be operated in a somewhat unconventional way.

[RedAero]

If I understand correctly that would mean a recoilless rifle has a much lower muzzle velocity than one with recoil, because the one with recoil has the overpressure to propel the projectile as well as the action-reaction principle.

[Some Guy]

That would be correct.

If both rifles are using rounds with the same amount of propellant, then yes.

new favorite vehicle

[Denver3000]

I suppose the reason why this vehicle has recoilless cannon is beacuse the recoil from 30mm probably would flip the vehicle over in 3-4 shots:P lol

LOL. It's very small. It's like driving a scooter with armor and a 30mm cannon.

[Evil.Iguana]

I have absolutely no real knowledge on the weapon system, but I'm going to make a wild guess that the weapon is not a "recoilless" system but rather a "low recoil" system. Recoilless would imply that the back end of the weapon is open. My guess is that it just uses a good muzzle break and lower power rounds with less propellant in them. Basically like the M-230 autocannon on the Apache as compared to the GAU-8 on the A-10. If you are doing gunnery against a fast moving target or using a KE penetrator then a lower power round is not the way to go. But with something like this, or the chin turret on the apache, muzzle velocity is not a major issue since your target is typically lightly armored vehicles or infantry and the round you are firing is HE.

[Hauptgefreiter]

It is open at the rear end. Afaik it's the same gun that is used on the Tiger, or at least one of the guns that have been developed for it. It's only a prototype, built as a feasibility study.

[GER_Mark]

it is open at the end
