Colloid thrusters as plasma-stealth and electromagnetic compressor systems. For next-generation aviation.

    Colloid thrusters as plasma-stealth and electromagnetic compressor systems. For next-generation aviation. 


The "electrospray" can work also as a stealth system.


The ion engines can give poor thrust. But those kinds of systems can used to make the ion layer between radar and aircraft or ships. The ion engine can also used to create an ion trail behind the drones. That is flying between the aircraft and the ground. 

The "electrospray" can be a useful tool in combination with technology where thin ionization is used to create an ion layer over aircraft and ship hulls. That kind of system can make the next-generation plasma-stealth systems possible. 

In those plasma-stealth systems, the ion layer pulls radar impulses in ions or anions. And that thing denies the radar echo. In some other models, the ion system makes the plasma cloud that acts like a "chaff dispenser" and makes the false targets for radar-homing missiles. In some other versions, the system loads opposite polar electricity to the target. When the target is loaded with minus electric load, and ions are delivered to the air, that negative electricity pulls those ions like protons or nitrogen ions to that target. 

There are two ways to make the electrospray that denies radar see targets. The first one is that. The aircraft or ship covers its shell with an ion layer. The other system bases that fast-flying drones or manned aircraft will pull ionic trails behind them. That ion or anion trail will deny the radar impulses travel through it.

"Diagram of principle of operation of a scramjet engine" (Wikipedia/scramjet)


The problem with those systems is the lack of compressors. It's hard to make a mechanical compressor that accelerates the airflow to Mach 7. If the compressor rotates too fast it makes a vacuum around it. And that makes it impossible to put that compressor at the front of the ramjet or scramjet engine. That vacuum pulls exhaust gas forward and that engine stops to give thrust. And the centripetal force can also break a fast-rotating turbine. 

In some visions, the compressor is behind the Ramjet. And that vacuum that forms around the fast-rotating turbine wheel behind the exhaust tube pulls airflow through the engine. Another thing is to use an electromagnetic compressor that pulls ion flow through the ramjet or scramjet engine. 

That means the aircraft must reach Mach 1 so that the ramjet engine can start to operate. The scramjet requires about speed of Mach 7. That it can ignite fuel that is hydrogen. If the system uses magnetic accelerators and ions it could accelerate airflow to the needed speed while the aircraft is in a stable position. 


The colloid thruster could be a suitable tool for hypersonic aircraft. The system can ionize gas for magnetic compressors. 


The problem with the ramjet and scramjet engines is that they have no compressors. The mechanical compressor that can push air to the super-, and hypersonic engine with speeds of Mach 5+ is hard to make. One solution that can respond to that problem is the electromagnetic compressor. The electrospray system or colloid thruster can used as an auxiliary ionizers for ion compressors. The ion compressor system pulls ions like oxygen ions into the jet engines. 

That kind of system is suitable for ramjet and scramjet engines. The ionization makes it possible for engineers to create a system that can drive gas flow in supersonic or hypersonic engines. The system pulls ionized gas through the engine. And that gas flow travels with speed. That is high enough that the engine can ignite the hydrogen. That is suitable fuel for super- and hypersonic systems. The magnetic compressor uses magnetic fields to create the gas flow that allows it to ignite the fuel. 

The electrospray system also can make the ions for the electric jet engines. In electric jet engines, the combustion is replaced by using an electric arc. The system can use the magnetic compressor to collect ionized gas for the electric jet engine. Then the system makes an expansion for that gas by using an electric arc. That kind of engine system are very powerful tool for the next generation of very fast aircraft.

Chinese innovations and space lasers are interesting combinations.

Above: "Tiangong is China's operational space station located in low Earth orbit. (Image credit: Alejomiranda via Getty Images)" (Scpace.com, China's space station, Tiangong: A complete guide) Chinese are close to making nuclear-powered spacecraft.  Almost every day, we can read about Chinese technical advances. So are, the Chinese more innovative than Western people? Or is there some kind of difference in culture and morale between Western and Chinese societies? The Chinese superiority in hypersonic technology is one of the things that tells something about the Chinese way of making things.  In China, the mission means. And the only thing that means is mission. That means that things like budgets and safety orders are far different from Western standards. If some project serves the Chinese communist party and PLA (People's Liberation Army) that guarantees unlimited resources for those projects. Chinese authorities must not care about the public opinion.  If we th

Iron Dome is one of the most effective air defense systems.

The Iron Dome is a missile defense system whose missiles operate with highly sophisticated and effective artificial intelligence. The power of this missile defense base is in selective fire. The system calculates the incoming missile's trajectory. And it shoots only missiles that will hit the inhabited area. The system saves missiles and focuses defense on areas that mean something. The system shares the incoming missiles in, maybe two groups. Another is harmless and another is harmful.  Things like killer drones are also problematic because their trajectories are harder to calculate than ballistic missiles. The thing that makes drones dangerous is that they can make masks for ballistic missiles. And even if those drones are slow, all of them must be shot down.  The thing is that the cooperation between drone swarms and ballistic missiles is the next danger in conflict areas. In the film, you can see how drones make light images of the skies. The killer drones can also carry LED li

The innovative shield that protects OSIRIS-APEX can also protect the new hypersonic aircraft.

"NASA’s OSIRIS-APEX spacecraft successfully completed its closest solar pass, protected by innovative engineering solutions and showing improvements in onboard instruments. Credit: NASA’s Goddard Space Flight Center/CI Lab" (ScitechDaily, Innovative Engineering Shields NASA’s OSIRIS-APEX During Close Encounter With the Sun) The OSIRIS-APEX probe travels close to the sun. The mission plan is to research the sun. And especially find things that can warn about solar storms. Solar storms are things that can danger satellites at the Earth orbiter. And the purpose of OSIRIS-APEX is to find the method of how to predict those solar storms. Another thing is that the OSIRIS-APEX tests the systems and materials that protect this probe against heat and plasma impacts.  The same technology. The researchers created for OSIRIS-APEX can used in the materials and structures. That protects satellites against nuclear explosions. That means this kind of system delivers information on how to prot
