Would covering tanks and armored vehicles in TPS tiles likes the ones from the Space Shuttle and the Starship make them completely invulnerable to ATGMs and EFPs? Wouldn't this be the perfect answer to FPV drones instes of cope cages?
>>65179013no. also, you're a fucking retard.
No, because you misunderstand how HEAT mechanism works. The penetrating effect of HEAT effect is kinetic in nature.I hear often how shaped charge round "burns through", "melts" etc. No. The jet punches a hole.
>>65179013>giant, allegedly rapidly re-useable rocket that literally is covered in components that eat themselves during every launchElon probably came up with this idea.
Let's go a bit more sci-fi while we're on the topic; would such tiles work against lasers or other DEW types? Even if only long enough to try to GTFO?
>>65179049Probably worse than ordinary metal because to beat lasers you want a material with very high thermal conductivity to spread the energy out. Reentry heat is different because the energy is already spread out and you can't spread it any more.
>>65179048They aren't ablative, they're specifically designed to be usuable.
>>65179057Every day's a school day. Thanks, friend.
>>65179042So the plasma "jet" doesn't burn at all?
>>65179013it might make them immune to flamethrowers.
>>65179192It does burn the people inside and ignite the ammunition, but those burn at low temperatures.If you've ever cut steel with an oxyfuel torch you know it has to get really very hot first before it starts burning.
>>65179013>a tile that has been known to cause catastrophic failure when damaged even slightly by foam>used as battle armorIndeed
>>65179192The jet is not plasma. Obviously it's warm in the sense of temperature, but that is an unimportant side effect. It is a stream of solid particles accelerated by an explosion to speeds where penetration is hydrodynamic. Think of a sand blaster or a water jet cutter aimed into a swimming pool, or an asteroid impacting a planet. At these speeds, hardness of objects doesn't matter, only the mass, speed, and shape do.
>>65179192Do you even know what plasma is? The jet is "superplastic" copper or whatever the liner it is.>The jet surface temperature is around 500-600 C for acopper jet>The melting point of pure copper is 1084 CIt doesn't melt. So it does not become ionized gas as well.
Based Retard, pushing the boundaries of science.
>>65179013i almost feel like this post was made intentionally as retarded as possible so to generate conversation and get people to start talking about spaceflight on /k/
>>65179192>So the plasma "jet" doesn't burn at all?It erodes the armor like a stream of water erodes earth. So does a long rod penetrator.
>>65179662>>65179419So "ceramics" work against HEAT, not because of heat resistance but due to Its hardness? Does this mean that Diamond would be the best type of armor against HEAT?
>>65179700>not because of heat resistanceCorrect> but due to Its hardness?Hardness is important. So are other factors like ultimate strength and toughness.>Diamondwould be very good because of its hardness, yes. That said, there might be some other material that has a better combination of hardness, toughness, and strength.Here's another way to look at it. Heat takes time to flow. You can touch a red-hot metal bar or pass your hand through a blowtorch flame without harm so long as you do it quickly. A bullet impact is super quick, a tiny fraction of a second, nowhere near enough time for an appreciable amount of heat to be conducted into anything. Heat is a side-effect of the impact, not the point.
>>65179609It can always be weaponized. Just lug some tungsten into orbit.
>>65179700It's both and neither. There's no such thing as ceramic armor. Ceramic is an addition to composite armor. Because of its different physical properties, and disrupts the formation of jet.
>>65179049Ill addProbably worse. These things are great at blocking heat, but heat is tricky. When you enter the atmosphere you create heat due to drag and compression. Thats hot, but you'll struggle to get hotter than the air because you're basically being air-cooled, just by air thats like 3000 degrees. This is fine for pannels that wont melt until 3001 degreesNow the laser is different. It just dumps energy into you, and we'll use water because its easy. 400j will raise 1g of water by 100 degrees, instantly vapourizing it. The water can avoid becoming a gas by flowing that heat through itself, and being generally dense. Thats why a burning a marshmallow will not instantly vapourize the surface of a cup of water. Now these pannels? They're barely 0.2g of silicone per cm^2 with zero conduction. So the pannel will be good up to 3001 degrees, but after 1.5s that pannel is becoming molten glass and the laser is hitting the hull. For reference a 400j per second laser is only 400 watts. Powerful, but you can get that much juice out of an ebike battery, so im calling it man-portable. That said, you need 1000w to cut 0.5mm of stainless steel. So this man-portable laser wouldnt even get through the bodywork on a honda civic
>>65179768>nowhere near enough time for an appreciable amount of heat to be conducted into anything.But compression and impact could easily raise your armour to it's melting point
>>65179700>Does this mean that Diamond would be the best type of armor against HEATProbably yes.It would absolutely suck ass for heatshields though, since it burns at ~700°C and has the highest thermal conductivity of any known material.
>>65179700Ceramics are used because of how they absorb energy: they crack into smaller granules instead of getting smoothly pushed to the side like steel.
>>65179700>>65179768The problem with diamond is that it burns easily, it's just carbon after all.And that it's expensive to create in bulk. Yes, artificial black diamond for industrial use is a looot cheaper than gem quality stuff, but still more expensive than silicon carbide and similar composite ceramics.>>65179013There is one weapons system that needs thermal protection.
