I have Started this topic to distcus a concept that is aredy a wile in my mind.

Any spacecraft faces the problem of enormous heat during re-entry due to the plasma generated by the hot phase. The chinse have now developt a energy shield that can feed from externel energy like micro waves.
it would bi a grate benefint when with sth same principal the Hot reentryplasma could be redireectet in to e electrical contollt heatshild.

is any one here who has some sintific knowhow with handeling plasma.

This seams for me a grate bracke throu. with many aplicationen

The  Tai- Chi is the princpel to use the Strent of the oponedt and turn it aganst him, without uesing your one strenth. So when you fire a laserpointer from scool, it turns back at you, when uesing  the industry laser the feald uses the power of the incoming laserenergy, to fead the sheld energy and turns also that against you. So even a nuclar plast gets absort and turnd Back.

There are some studies on something called magnetosphere aerobraking.  IIRC, the problem is that they work best with very high velocities (higher than you would get on a return from LEO. There are some ideas on seeding the plasma artificially but that then comes with other problems. I still find the concept extremely interesting and I wished they would explore it more.

The link you posted seems to be about something to protect against microwaves, which I don't think is applicable here.

I have started this topic to discuss a concept that is already a while in my mind.

Any spacecraft faces the problem of enormous heat during re-entry due to the plasma generated by the hot phase. The Chinese have now developed an energy shield that can feed from external energy like microwaves. It would be a great benefit when if, with the same principle, the hot reentry plasma could be redirected into an electrically controlled heat shield.

Is there anyone here who has some scientific know-how with handling plasma?

This seems to me a great breakthrough, with many applications.

The Tai Chi is the principle to use the strength of the opponent and turn it against him, without using your own strength. So when you fire a laser pointer from school, it turns back at you, when using an industrial laser the field uses the power of the incoming laser energy, to feed the shield energy and turns that also against you. So even a nuclear blast gets absorbed and turned back.

Sorry, that was going to bug me...  :o

As mentioned, the linked paper is a defense against microwaves and not reentry plasma. But it seems the basic proposed concept is, could you have an active electromagnetic heat shield that is (due to large power requirements) somehow powered by the reentry plasma itself?

Yes That was actualy my idea.
the dificulty is to hannest the energy form the reentry plasma and somhow controll it.

Yeah the magnetosphere aerobraking is one thing, but I thing the concept coult help a heatshild, so that the hot plasma son not touch the reentry vehicle.
Is there sombody that has expieriens with plasma. plasma welding and maybe made som exoeriments in that feeld?
