Looks like some interesting technology that could bring on the next wave of suppressor development, if the claims are legitimate. Sign me up for a light, reasonably quiet, and cool can if they can make it for a price that doesn't necessitate being a government entity to afford one.

Is it simply an insulation layer holding the heat away from the outside material layer or does it have some miracle properties that allow a super fast dissipation of the heat?

hehe... the question of what their barrel system actually does, and how it does it, has been hotly debated by people who either know science or think they do for many years and I won't try to repeat it here. There are some patent docs available to dig into if one is so inclined, but the secret sauce recipe is still a closely guarded secret. Suffice to say, if it was just insulating then it would be very easy to prove by monitoring the internal temperature of the barrel. Various people have done that and there's no question at this point that the system does what they say it does. In short, it moves heat out of the barrel and gets rid of it. Here's the latest guy who's digging into it: The New Rifleman and Teludyne Tech
So I would really doubt that they are just insulating the suppressor. Did you guys see the image where they measured temperatures after 150 rounds? It's in the 1st link. |

I would guess something along these lines. We use it to prevent high heat transfer in areas that flammable cannot be removed. I wouldn't know how long the properties would last, if it were to be contained between two walls of a suppressor.

I was thinking more along the lines of heat pipes - something like this from AAvid Thermacore. The rate and amount of heat that can be moved from the source is pretty impressive. We use some of their heat pipes in our thermal management applications and they have a demo kit comparing the thermal properties of their heat pipes compared with copper and the results are amazing.

That sounds impressive. How physically durable is the jacketed barrel setup to breing manhandled? However, they are very responsive on FaceBook so you would get a better direct answer to that or any other question by asking there. For what it's worth, Falkor gives a lifetime guarantee with their Dracos barrels--that ought to tell you something! |

He didn't hurt his straightjacket but he ended up bending the Mauser receiver.........so its rugged. |

They are using an aluminum/steel composite construction.
To maximize the contact conductance between the steel inner bore sleeve and outer aluminum housing, they are using a pressure fit and a thermal contact paste - regardless of one's machining capabilities, a metal-metal interface will always have surface irregularities that limit the surface area contact and effectively acts as an insulator - thermal contact paste help to lessen the contact conduction effects. The aluminum has a thermal diffusivity that is 10-20 times that of steel, that is to say that thermal energy diffuses through the material 10-20 times faster than through an equivalent thickness of steel. Furthermore, the barrel has a larger outer diameter, which increases the surface area exposed to convection, increasing the overall heat transfer rate. So, it's a matter of balancing the thermal optimization against mechanical strength and vibration. |

They probably are using a chemical of some sort that either boils or sublimates to get rid of the heat. Or water - when it is boiling it can never get hotter than its boiling point because the water absorbs huge amounts of heat to convert from water at 100c to steam at 100c. Similar to putting an ablative inside a silencer(water, oil, gel, etc). A water cooled machine gun will never get hotter than 100c unless you run out of water.
The problem is that if you run out of the chemical you are using to get rid of heat then the gun will heat up extremely fast until failure, just like letting a boiler run out of water. |

10 rounds sub moa group fired semi-auto. Also the barrel radiates heat like crazy. I could feel heat on my face from the shooting posiiton, and that's the first time I have ever noticed that before. Whatever they are doing with their suppressor... wew. |

Beyond suppressor use, if this new technology pans out, imagine its possibilities on reducing the thermal signature of our stealth airplanes.

Conservation of energy. Got it now, suppressor with tube that traps heat, opposite of their barrel jacket that dissipates heat. The barrel in the photo has their barrel jacket, this could be absorbing and helping to dissipate the heat from the can. However, the 1k heat in the can is now transferred to your barrel?

I'm still not clear if Teludyne is involved with this or just connected to the designer, but Scotg_ put out a couple more videos on Instagram about it recently:
https://www.instagram.com/p/BYR7RBmhk6S/?taken-by=scotg_ https://www.instagram.com/p/BYTdDn_hXKK/?taken-by=scotg_ The account is labeled as a range and training facility, so again I don't know exactly who's behind this design, but here are some excerpts from the comments: ----- this technology should be an #industry #standard by 2018 as this technology will be licensed to companies that have there shit together for civilian sales... there are already companies that will soon use this tech and if the others don't they will soon become irrelevant, as this tech decreases blowback, won't burn you, and won't create a mirage. Just to name a few improvements this has over all other suppressors. But like they say you can lead a horse to water but you can't make them drink... Absolutely no gas out of the ejection port! This #suppressor tech. Works like a bore evacuator! Plus it won't burn you with db of 132 out of 10.5" barrel! ----- The good news is it looks like Pete from TFB (That's GoLoud here, right?) is digging into it, so hopefully he'll get us some more details soon! |
