A question about the RPG.

3===SPECTER===3 · Post by **3===SPECTER===3** » 2007-05-20 21:09

Sorry if i posted in the wrong section. But is it realistic to have the white smoke following the RPG like its a missle? would it be possible to change it to black/gray smoke or no smoke at all. maybe even give the gun more smoke effects when its fired so its easier to detect.

sorry if its been asked before. i searched it and found nothing

Not trying to be a smartass here...but id rather see the dev's concentrate their excellent efforts on other more important things to get .6 as quality as possible rather than tweak the visual effects of the RPG

I know people love to post this ^, but I don't think changing a few color values on a smoke trail would take more than a few minutes.

yeh would be nice if the smoke trail effect could be taken completely out cause it evaporates so quickly apc's and armor barely see it... especially when it comes from their 6 so i dont really see the point in having a smoke trail

RPG-7 Manual
The propellant is a smokeless powder.
Here is a quote from the manual:

Firing Signature
Tests have shown that the smoke from the intial firing backblast is slightly larger then that of the US M72A2 LAW. The initial booster productes a smoke puff 3 to 4 feet in diameter which lingers up to eight seconds in low winds. The sustainer rocket ignites about 11 meters from the launcher and produces a bright flash and a second smoke puff similar to the initial blast. The possibility of locating a RPG-7 from its firing signature is of course dependent on battlefield conditions. Smoke and wind will reduce the initial backblast smoke, but in a position in woods or some cover, the smoke will stay longer. The flash and smoke from the sustainer motor will probably be more visible and procide a general indication of weapon type and location, particularly at night.

nice ! RPG smokeless FTW

Why are you do you have?

Please keep this on topic, if you have a pointless question about the contents of my signature then please PM me.

The AT-4 could lose the smoke as well since it's a recoilless gun not a rocket launcher. Rocket motor propellant burns with a white smoke anyway.

ATTENTION: The video posted below was posted in the intention to show an example of the smokeless powder and the RPG-7 firing at a long range, NOT for propaganda purposes.

As you can see theres no thick white smoke trail from where the RPG was fired to the impact point. Thus showing in reality, a smoke trail is not present behind the RPG rocket when fired.

Smokeless powder is nitro cellulose based, in it's purest state it hardly emits any smoke, but storage over time and components inside nozzle will give it a smoke trail

Silens.Intro · Post by **Silens.Intro** » 2007-05-21 06:21

Single-based smokeless powder is Nitrocellulose based.. Double-based is Nitrocellulose combined with up to 50 percent Nitroglycerin and Triple-based is Double-based with added Nitroguanidine.
Although I'm not sure which base of smokeless powder is used to fuel the RPG-7 rocket..

Also, if you don't mind Guerra, could you give me a link as to where it says that storage over time and components inside the nozzle will give the RPG-7 rocket a smoke trail when fired?
I stand firm in me saying that an RPG-7 rocket does not have a thick white smoke trail behind it as can be proven from these videos:

The only smoke you can see is that of the initial booster and the rockets ignition, no trailing smoke.

Please tell me that you have a valid source on this! Because it would be a shame if you stated things without backiung them up with facts!
Yeah, it's a recoilles weapon but its not a rifle, I also checked the FAS website where they state it's a recoiless-rifle, but untill someone can prove me wrong (Bob_Marley?) I will say that that is very wrong! The fas-website seems to very inaccurate on other matters aswell, stating that the AT-4 is able to penetrate over 350mm of armor, the standard version penetrates 60mm.

No I can't because my statement is based on my knowledge of rocket engine construction and improvising various propellants and explosives, I'm not saying that the RPG will have a huge smoke trail like now, but it won't be completely invisible either.

Here's the best info on the AT-4 I could find, some sites did say that it was a rocket but most don't. As for white rocket propellant you just have to look at pictures of missile launches to see that.

The AT-4 does not have an rocket. Its a true "recoilless" weapon.
Warhead goes forward, "smoke" goes out the back.

Here is a cutout of the warhead:

(BOOSTER is refeering to the initial charge that sets of the main HEAT-charge, same function as the primer in an normal rifle cartridge)

Guerra norte · Post by **Guerra norte** » 2007-05-21 17:03

The AT-4 works on the principal of "every action has an equal and opposite reaction", basically it's a two sided cannon if you will, one side shoots out the projectile and the other shoots out the counter weight.
Actually I'm very surprised I haven't seen any improvised counter weight launcher made by Iraqi insurgents as they are extremely simple to build as opposed to hand held rocket launchers which needs and ABOL booster, and not forgetting all the troubles with making reliable sustainer rockets with delays.

Recoiless just means that the initial boost uses backblast to keep the firer from being thrown back. A rocket can still kick in. What are you guys talking about?

EDIT: Damn you GN and damn your typing skills too...
