Avangard has new doubts: "Avangard has no trace of 27 Machs or even 10 Machs."
Around Russian hypersonic weapons, new doubts arose.
Despite the fact that Russia is considered the first country to have developed, created, successfully tested and adopted hypersonic weapons, a lot of doubts still arise around this topic. One of these is the famous Russian blogger El Murid, who suggested that Russian hypersonic missiles are unlikely to be able to accelerate above a speed of 10 MAX.
“The point here is that even at 10 Machs, the braking temperature reaches about 6 thousand degrees in dense layers and something about 4,5 thousand in the upper layers of the atmosphere. At 27 Machs, one must understand that the temperature will already reach five-digit numbers (that in Celsius, that in Kelvin - it makes no difference). What kind of material is capable of withstanding such temperature loads - I personally, as a layman, do not know. I just remember the melting point of the most refractory tungsten metal at 3400 degrees, and also know that the most refractory material is generally considered a composite of hafnium and tantalum carbides, which can withstand heat up to 4 thousand degrees Celsius and, accordingly, up to 4200 Kelvin. Apparently, they managed to find something absolutely outstanding in the secret laboratories of Russia ”, - the blogger describes the situation, accompanying all this with visual tables.
It should be clarified that the issue of heat removal was indeed often raised even by experts, however, contrary to the arguments of the blogger, analysts pay attention to the fact that, in addition to Russia, China also has hypersonic weapons.
“For many years now, China has been in service with hypersonic missiles, which are equivalent in speed to the same Russian Avangard systems. Nothing burns, melts or explodes. However, there is always a non-specialist who will point out the physical and chemical properties of refractory materials, completely forgetting about the same composites specially designed to remove heat energy ", - the expert notes.
Among other things, the United States demonstrated the successful acceleration of a special test shell to a speed of almost 9 MAX, which, oddly enough, could not warm up to critical levels.

ohhh ... I see the whole beau monte, the top of the geniuses gathered here. Physicists, chemists, rocket scientists .... I thought that you were no longer in nature ... Here you are !?
This El Murid said a week ago that GAZPROM agreed to a double tariff for pumping gas through Ukraine. In fact, the tariff increased by 8%. Given that the tariff will be unchanged for all 5 years (dollar inflation will be, but there will be no tariff change), GAZPROM defended the previous tariff. I will not even talk about Putin’s non-identifiable illness, which is known only to El Murid. Iksperd is still one.
"Vanguard" as well as "Flurry" is a secret development, which is the principle of its movement with such speed. And the essence is either in the material or the cooling system, or on it there is a plasma generator koi developed in the USSR back in the 60s, no one will prompt the Chinese or Pindos.
Let this millennial blogger break his brain: how does an autogenous burner produce almost 3200 Kelvin :), being made of brass? Where is the shaitan !!!
Hello again! As always, the notorious AVIA-Pro reports market news! One vomit, not news!
Before writing, the author of the article should read the basics of heat engineering. In a "cold copper crucible" developed in 1950, the melting temperature of materials is limited only by the intensity of cooling of the crucible tubes. The role of the crucible vessel is played by the melted material itself (skull), which remains cold at the cold tubular walls. Therefore cooling technology is more important here. For 70 years something has worked out.
hehe found no one to refer, this couch expert on a salary, working out his piece of bread
but in fact the heating depends on the flight altitude
ballistic missiles also consider hypersonic 1 space 8km s and nothing will go into orbit
heating takes place in the lower atmosphere less than 30km
apparently the avant-garde and Chinese counterparts of the rocket fly at least 40 ~ 50km
and who is El Murid, is he a heating engineer or rocket engineer? Let Amers ask, they track these launches, and then he opens his mouth.
Is this when shepherds became experts in hypersonic weapons? They can’t count the sheep !! El Morid is an obvious shepherd, from Jailau!
The Vanguard has no doubts !!! This is your point played!
Dumb bloggers sticking their noses where no one poked anything, now divorced more than a lousy flea dog. And respond to each such?
funny Nesmyan again sniffed at his English hosts.
