A heat sink would be way ...That's no heat sink. A heat sink would be way too heavy; LMG versions of assault rifles have a thicker barrel to serve as heat sink (mass cooling) for the higher expected practical rate of fire.<br /><br />It's fairly easy to create a device to hide a thermal signature for a while. This was already done to flame dampeners of piston engines during WW2; that's why the passive "Spanner" IR night vision devices of German night fighters failed. They were excellent against bombers with no flame dampeners and still useful against bombers with primitive flame dampeners, but bombers with flame dampeners and some additional line of sight block were not detected at useful ranges.<br /><br />You merely need to reflect the radiation with a reflexive surface facing the hot part and on the outside of the hot part (chrome lining, for example), and in your example they limited the heat transfer by convection by using a rather impractical vacuum (some gases such as in double windows would insulate as well).<br /><br />This thermal sleeve approach has several severe and obvious problems<br />- sealing is guaranteed to fail in the infantry context, vacuum is thus practically irrelevant unless you pump air out often<br />- the barrel transfer its heat almsot exclusively through the muzzle or into the breech. This may worsen the cook off problem, worsen the smoking barrel problem and certainly also reduced the qty of shots fired before barrel overheats.<br />- pretty guaranteed to be not practical with quick change barrels<br />- vibration and thus dispersion issues (though this may be acceptable for a machinegun)S Ohttps://www.blogger.com/profile/03359796414832859686noreply@blogger.comtag:blogger.com,1999:blog-386077914312449748.post-63344485436514209892015-11-21T05:34:21.171+01:002015-11-21T05:34:21.171+01:00Hey, remember that article you wrote on thermal ca...Hey, remember that article you wrote on thermal camouflage back in 2008? And then in 2012 where I mentioned the action at wanat, and how machine guns should have both suppressors and heat sinks? It seems that someone finally caught on to this.<br /><br />http://www.defencetalk.com/thermal-cloak-prevents-weapon-detection-by-thermal-imagers-62182/<br /><br />Years ago, my engineer friend told me that a thermal barrier coating would be superior to water cooling.

It intends to establish fear and insecurity among the population and the institutions.<br />But those activists/(t)errorists are (self) conscious that such acts ‘cannot radically change the politics in a society, nor a society.’<br />So, those operatives tend to spread fear among the population and they try to shake the state institutions which seem to be unable to ‘protect their citizens against subversive/(t)errorist attacks’.<br /><br />The international micro-Tet offensive by ISIS in the last few weeks, if it is confirmed as an offensive, does not show signs of Special War, yet. But if it does in the future, we will have to deal with a much greater enemy than what our eyes can see.<br />Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-386077914312449748.post-2520098325793778922015-11-20T00:23:22.905+01:002015-11-20T00:23:22.905+01:00And what makes it even more interesting is that yo...And what makes it even more interesting is that your preferences are modulated by your ethical beliefs.
