The idea is not mine It come from the 2006 Conference on "piercing the plasma"
Defeating blackout is not simple for sure But it is not impossible . Various scheme has been considered and they even have conference in 2006.
Sofar they can live with it but as the hypersonic vehicle come into being. They will solve the problem. The Chinese has no alternative but to solve the blackout Or their system will not function.
Here is the quote from Scientific America a
A variation of electrophilic injection might be a strong contender, however, using a heat shield made of an ablative material that vaporizes parts of itself and deionizes the plasma. “In terms of an engineering solution, that seems like the simplest,” Jones says. Meanwhile Lewis considers himself “a stone agnostic. We’ve got a number of avenues to explore, and I think we’re still at the point where all those avenues should be on the table.” Jones has noted that a combination of techniques most likely will be required to meet all anticipated applications.
