I'm researching that piston pump project, and can't find anything from
LLNL after approx. 2005 :( . Did they stop working on that?
Yeah, I don't recall seeing anything new from them in a long time. Most
likely, they simply ran out of funding, given the lack of funded
applications for the technology, and the general impoverishment of LLNL
after the end of the Cold War.
Where's that information about comparative simplicity of HTP vs. N2H4
comes from?
I had thought it was in either "Hydrogen Peroxide Propulsion for Smaller
Satellites", Whitehead, Smallsats 12, 1998, SSC98-VIII-1, or "Progress
Toward Hydrogen Peroxide Micropropulsion, Whitehead et al, Smallsats 13,
1999, SSC99-XII-5. A quick skim doesn't find that exact discussion in
either one, but I may just have missed it.
