Modeling supressors

Yes, it can be legal to make a silencer. For everything Form-1, from silencer designs that are easily made, to filing forms with the BATF, to 3D modeling. Remember, you must have an approved BATF Form-1 to make a silencer. All NFA laws apply.

Modeling supressors

Post by Hamond »

Hi guys.
I'm Eugene from Hamond LTD ( www.hamondrifle.com), located in Ukraine .
We have a small-scale silencers production, as well as develop new designs.
We offer our help to anyone who wants to try himself in improving the efficiency of silencers.
For these purposes, the topic has been started in Russian forum, but moderators have deleted
it and continue to remove over and over, for unknown reasons. Everyone can read the entire archive
of deleted messages over there: http://guns.allzip.org/topic/117/1951739.html
I suppose, such information can be interesting for the participants of your forum, so I would prefer to duplicate
our activities here. http://forum.guns.ru/forummessage/117/2038452.html
I would like to start the discussion of silencers improve, to allow you to test your
ideas with the (absolutely free) assistance of our experience. We ask only one thing - tolerance
 to our poor English.

This is very cool. I'd love to see one of my designs modeled like this. What type of computer file would you need from me in order to test it?

you can check out our YouTube channel for links http://guns.allzip.org/topic/117/1951739.html, so you'll find more videos

Rich93ds, we have not been able to convert your model to calculate. serg-pl is still trying. if he fails, he will make new ones.
Your model is too simple and not very interesting, we made the calculation that they would meet your interest and hope to see something more complex in the future.

To not require 3D printer, images baffle

At this stage we are looking for optimal solutions to the gas flow. Some decisions go further, others are discarded. We will think about technological solutions when we get a good reduction in the output speed

It's not just you. There were some images here earlier. But I figured it may have something to do with being located in Ukraine.
I don't care what your chart says

On review of this design
Image

I think the "snout", at the baffle's entrance, is going to hurt your intended cross-flow into the coaxial chamber. Also, the cut, allowing entrance to the coaxial volume, seems too large. Yes, you want gas to get in there, but you want to make it difficult to leave. A smaller hole is ok because it will have the aid of higher pressure, along with the cross-flow jet, forcing it into this area. Once the gas has entered and expanded the lower pressure will make it more difficult to escape a smaller orifice.

The blast cone should do a nice job of allowing the initial impulse to expand, while limiting the amount of gas following the projectile.

This design would use a smaller OD tube than the other one, which shows a much larger coaxial chamber for the length of the suppressor. Obviously, the sheer volume of the added coaxial chamber should be sufficient enough to make the same design yield a greater dB reduction. This, however, does not lend to an efficient baffle design, at least not necessarily so.

That's my $.02 :D

Here's the idea today
In two variants.
Considered in SW Flow Simulation
At the inlet fed 2.8 MPa and at the output atmospheric pressure.
Yes, I know that this is not true, and at the input pressure should be given a curve, but I still do not know how.

I had little time but managed to make one simulation
Have patience, we now have a lot of work. As soon as the opportunity appears I will do the rest of the simulation

In the future, we will simulate this model without the first cone.
