PDE research has been getting small study grants for nearly 50 years. Why
would you expect a breakthrough now?
Because, thirty years after Apollo, I am experiencing boredom and impatience
with the lack of CATS which a simple high performance chemical engine would
relieve.
I think that creating and controlling continous explosions inside a rocket
tube is not that much harder than designing a chain gun. So where, pray tell,
after fifty years, are the PDE developments?
Could it be that they would make such excellent CATS ships and cheap,
easy-to-make missiles that they are being withheld for our own "security?" [the
very same reason that manned spaceflight has been so utterly stagnant for
thirty years?]
