Russia-Ukraine War - News, Discussions & Updates

Meh. They can't even beat sandal wearing people in Iraq let alone beat Russia.

That’s why Putin frees convicts from prisons. Beware of hooligans and rapists. They are sent to Ukraine. They are the mighty russian army.

Russian kamikaze drones "Geran" again attacked Kharkov and the Kharkov region on the night of April 4. The strikes were carried out on energy infrastructure facilities and facilities where, according to Russian media reports, military personnel were stationed. In Ukraine they are already announcing the destruction of 80% of generating capacities; eyewitnesses filmed videos of the attacks that occurred right next to them.

I have learnt a lot in my life. Don't want to learn any more.
The more I learn, the more I feel pity for you people.

Thanks for proving my point yet again. Not only do you have a closed mindset you no longer care to learn.
Wow

Saudis are not going to spend even one dollar. Even the worst of Saudi and other middle east kings saw west's atrocities in Palestine case. Get out of day dreaming. All their riches will be used to rebuild the world after the upcoming nuclear apocalypse.... After complete elimination of Zios and Nazis etc.

The only one sounding like a nazi is you.
Nazis burned books and you refuse to learn anything new, see the similarities?

They just deployed Zirkon now They use Kinzhal and I saw some of the warheads purportedly shot down by Ukro. But to me, they all look like dumb bomb blunted, round heads. Typically Hypersonic warhead is of double cone type or very pointed warhead with a wing. They are double cones for a reason.I asked copilot here what copilot said

The double-cone configuration is a fascinating subject in the realm of hypersonic flow. Let’s delve into why it’s significant:

1. Shock-Wave–Boundary-Layer Interaction:
   • When hypersonic flow occurs over a double cone, it represents a canonical case of shock-wave–boundary-layer interaction.
   • This interaction involves the shock waves generated by the supersonic flow interacting with the boundary layer around the cone.
   • The double cone allows us to study this phenomenon in a more complex three-dimensional context compared to its two-dimensional counterpart (such as a double wedge) 1.
2. Insensitive to Small Bluntness:
   • Research indicates that the double-cone flow is insensitive to small bluntness in terms of shock structures, separation region sizes, and surface pressure and heat flux distributions.
   • However, there exists a critical nose radius beyond which the separation bubble grows dramatically.
   • This critical radius is crucial for understanding the behavior of the flow 2.
3. Leading-Edge Bluntness and Flow Features:
   • The sudden change in flow features is primarily caused by pressure overexpansion on the first cone due to leading-edge bluntness.
   • When the nose radius exceeds the critical value, the separation bubble expands significantly.
   • Upstream pressure can no longer resist the large adverse pressure gradient induced by shock impingement 2.
4. Triple-Deck Formulation:
   • Researchers analyze and interpret the numerical data based on a triple-deck formulation.
   • This formulation considers the interactions between the shock wave, boundary layer, and inviscid flow.
   • It sheds light on the underlying mechanisms driving the flow behavior 2.

In summary, the double-cone configuration provides valuable insights into hypersonic aerodynamics and shock-wave interactions. Its behavior is influenced by factors like bluntness and critical nose radius, making it a captivating area of study in fluid mechanics and aerospace engineering.

This is Hypersonic warhead

More excuses, admit it the zircon is junk just like most of what Russia produces.
