China plans to make a giant railgun for launching satellites to orbiters.





China plans to make a giant railgun for launching satellites to orbiters. But what else should it launch? 


Jules Verne's novel "From the Earth to the Moon" introduces a giant cannon called "the Columbiad". This giant multi-chamber cannon sent the main characters on a Moon trip in this Victorian-era novel. The cannon couldn't send the manned spacecraft to the orbiter. But the idea remains. 


The firing of the fictional Columbiad (Wikipedia: From the Earth to the Moon)




In the 1940's Nazi German researchers tested the multichamber cannon called V-3. The problem was that explosives detonated wrong times in those chambers on both sides of the barrel. The V-3 could shoot the arrow-looking grenade with tail wings to long distances. 

Then researchers suggested that NASA could make the long railgun to the side of some mountain. That could allow shoot Pegasus rockets to near the atmosphere's edge. NASA rejected that plan. But now Chinese developers are making that kind of system, that could shoot small satellites to orbiter. 


China has developed railgun technology for the navy. And that means this giant railgun has military applications. 


But we all know how interesting the Chinese are about spaceborne military applications. Their miniature shuttle is one thing, that can have an ASAT role in the military service. The shuttle is quite similar to the X-37B. It's seen under the Harbin H-6 bomber, but the magnetic railgun can make its operations more effective.

Chinese developers plan to make a giant railgun or electromagnetic accelerator that could launch small satellites to orbiters. The giant railgun is a powerful tool. The idea is the same with particle accelerators. And the difference is that the magnetic accelerator accelerates a small rocket or satellite to the orbiter. Chinese military can use those small rockets as ASAT weapons against other satellites. 

The railgun can shoot things like Pegasus-size rockets into near space edge. And there that rocket can ignite its engines. The thing is that the small-caliber railgun makes a new type of military threat to the Western world. The small railgun can shoot similar nuclear grenades used in Operation Upshot-Knothole Grable-test.

The 200-300mm. 15 kiloton nuclear explosive is a hard target for the defense. And the railgun can accelerate them to the intercontinental flight. Another thing is that small hypersonic gliders can also cause problems for western forces.

Plasmonic waves can make new waves in quantum technology.

"LSU researchers have made a significant discovery related to the fundamental properties and behavior of plasmonic waves, which can lead ot the development of more sensitive and robust quantum technologies. Credit: LSU" (ScitechDaily, Plasmonics Breakthrough Unleashes New Era of Quantum Technologies) Plasmonic waves in the quantum gas are the next-generation tools. The plasmonic wave is quite similar to radio waves. Or, rather say it, a combination of acoustic waves and electromagnetic waves. Quantum gas is an atom group. In those atom groups, temperature and pressure are extremely low.  The distance of atoms is long. And when an electromagnetic system can pump energy to those atoms. But the thing in quantum gas is that the atoms also make physical movements like soundwaves. It's possible. To create quantum gas using monoatomic ions like ionized noble gas. In those systems, positive (or negative) atoms push each other away.  When the box is filled with quantum gas and som...

What is the difference between TR-3A and TR-3B? And are those planes real?

What is the difference between TR-3A and TR-3B? And are those planes real? Is TR-3B (0) "Black Triangle UFO" or is it only the piece of paper?  The study project, what is used to create advanced ideas for use of the nuclear-powered aircraft. Or is it the study project or black budget aircraft, where lost 2,3 trillion dollars (1)of the stealth bomber were gone. In this text is things, that might seem very difficult to accept, and when we are thinking about things like doubling the object or making it smaller by using huge layers of energy, nothing denies to test those things. But were those tests successful, there is no data about that in public Internet, so we must say that things like doubling the human or aircraft can be tested, but the results can be unknown.  But in the source two is the tale, what seems like impossible, those men, who got Noble Prize put at first time one atom to the box, and hit it with photon one photon in the box and hit it with t...

The interesting coincidence between USS Sea Shadow (1982) and CSS Virginia (1862)

Image I The interesting coincidence between  USS Sea Shadow (1982) and CSS Virginia (1862) Far away from its time is the thing, that you might notice when you see those two images. The upper one (Image I) is portraying the modern naval USS Sea Shadow (IX-529)(1) experimental Stealth ship, which was created by Lockheed-Martin, and the image below (Image II) is portraying the CSS Virginia (2), the ironclad from the Civil War Era. The thing why the hull of the CSS Virginia, what is ironclad from 1862 is that the ammunition of the cannons would not transfer their impact energy to the hull of the ship. And the reason why Sea Shadows hull has this form is that it should point the radar echo away from the hull.  The thing that I must say that CSS Virginia is far ahead its time because that structure is effective against the explosive ammunition, and the slanting armor of tanks like T-34 and Sherman have made them effective. But for some reason, the use of slanting ...
