1993 NASA doc on releasing payload at hypersonic speed
Again, some people who can't bear to see their home team fall behind trying to bring up old papers and models to show "See, we have looked into this. No biggie." NASA may have been on it once upon a time. I'm pretty sure USSR/Russia had been on it too back then; the research papers now rotting under a leaking poorly funded lab somewhere (considering that they actually deployed a FOBS and low throw weight and duration of flight were a small concern for them).
But have these countries tested atleast a prototype?
The two papers he touts talks about ground tests in a wind tunnel (not the whole system but just the detaching component).
This from Chris Comb, who seem to be coping to the news so hard, he accuses (covertly) that China copied !
Show me a similar test to the Chinese one. Until then, dismissed. And the professor gets a D for the effort.
