Why don't they make silencers like that? Pardon my shitty paint skills.
Well I'm entirely guessing at this but IIRC the loud boom is made by the gasses expanding from the change in pressure from the inside of the barrel to the outside space
To effectively mitigate this the gasses need a buffer zone where they can expand in a controlled area. Your design is too open and it would still be extremely loud because the silencer is too short and the gasses could easily quickly expand out the end of it
Feel free to shit all over my post if I'm wrong
I got better idea.
See, with this design all the noise gun made will be directed backward, so nobody in front of shooter will ever heard a shot.
Colors are pressure forgot to mention in the picture
No, that's exactly right. It's basically the same principle as a car muffler, the hot compressed gasses have energy that will become sound. By allowing them to expand within a contained space and slow down, you disperse that energy without generating sound.
Here is a diagram of a suppressor. You can see, as you summarized, that it starts with a chamber for the gasses to expand in.
See? Fluid dynamics makes it work silenter
But it wouldn't really offer any advantage over a traditional silencer design. The most interesting thing it would do is pitch-shift the sound of the shot with all the different length gas tubes.
It's not a silencer, it's a gun tuba.
so youre asking for a bullpup silencer basically?
All the benefits of sound suppression without the extra length?
If there was a proben design that would work, someone much smarter than us would have designed and profited allready.
Would something like this work? Essentially multiple tubes with compartmentalized sections divided along the radii
It could, but you really want baffles in the center line too. In your design all of the gas still has to escape one hole at the end, so most of it is going to go right out the front.
Keep in mind that sound is the enemy. You want to reflect it back and fourth so it is attenuated and absorbed.
All those extra spaces don't do shit. Remember that peak pressure only exists very briefly. By the time any significant amount of gas has become trapped in anything but the first two sections the gunshot is long over.
Pro-tip: Inducing turbulence in the bore line is much more effective than simply shaving and trapping gas. And when it comes to shaving and trapping high velocity gasses nothing beats (stepped) cones.
Well it's not perfect, I guess my point was having a baffel design including multiple tubes in each other of various diameters. It seems like that could mend with the typical cone-shaped or angular baffel design pretty well as well
I have to add that stepped cones are so effective because it's a very simply design that combines turbulence of hard angles and the shaving abilities of cones. Add some holes into recessed spaces along the outer tube and you have the best a simple homemade suppressor could offer (unless you're willing to put up with the weight of a monocore).
If you want unnecessarily complicated then check pic related. It's basically a series of overlapping fixed turbines followed by turbulence inducing asymmetry. It's not actually better than any existing suppressor at suppressing. All it boasts is removing backpressure and being fragile as shit.
And if you want (effective) art just get this
As for (relative) simplicity it doesn't get more effective than this.
Check out OSS suppressors.
They're the most "technically advanced" designs currently around.
Whether they work any better than "less advanced" suppressors is probably debatable.
Motherfucker I just tried to post this pic probably seconds after you.
Vintorez suppressor is literally just three baffles
Check out Ops Inc suppressors if you want the opposite.
Battle proven military supplier, super simple baffles, all steel full weld. Sadly because of that last part you don't find many pictures.
>more to do with the [...] sheer volume than the design
Yes, now you get the idea
you're pretty much right. that shit arrangement pattern of the buffer space in the OP diagram ensures that there's minimal suppression of sound, because the place where the the gases have a chance to begin to expand inside the suppressor is very near the exit, so very little of the gass will be diverted and contained, thus the reduced bang would be absolutely insufficient.
tl;dr it would still be loud as fuck
These just remind me of Fleshlight cross sections
You can only pitch shift so much sound so much within a given frame.
If you built a suppressor the size of a small shed, then yes, you could build a very intricate canine owner torture device.
I haven't seen a cross section but the delta p design brevis suprressors are cool. 3d printed from incolnel or titanium and much shorter than your average suppressor. Id buy one if they made a 9mm version.
Gases are not good at making sharp turns like in your picture, and if I had to guess one of two things would happen
1 - the baffles don't really trap any gas at all and the shot is still loud
2 - the pressure build up in the front part of the baffles gets too high and your suppressor now becomes a frag grenade
What do you think of OSS supressors?
You aren't disrupting the longitudinal waves in air like sound-dampening foam does. You're stopping the motion of expanding gases from creating that pressure wave in the first place.
