Report of Officers


    • Received email confirming registration for lecture on accelerometers etc. all day Thursday, June 17th.
    • Julie can’t go. Does anyone else want to?




    • Michael W reported that we still have money
    • An update to the members list is in the works
    • Is still working on bank statements and back taxes. We may have to do manual data entry.
    • There are six and a half years of data to catch up on.


      Nothing to report (because Michael W forgot to bring the paper copies of SI100 notice, etc, that were recently filed on behalf of the group).

Outreach & News

  • Maker Faire booth went very well.
    • We had a prominent table in front of the HRP and model rocket groups.
    • Stellan had the mockup of the BiProp rocket, which stood taller than any other exhibit
    • Dan brought several engines along:
      • a 5 lb thruster engine,
      • a 30 lb POGO engine
      • one of Kevin’s spun-cast 50 lb engines, and
      • the KISS engine, tank and pressurant module

    • Michael used his laptop and Gerry’s projector to show launch videos, presentations and data
    • The people who staffed the booth spent a lot of time talking to passer’s by
    • Despite lots of interest, no new joiners so far

State of Test Site

  • Dan reported on site issues.
    • Plumbing and ditch work is needed
    • Brush clearing work needed too
    • The old blockhouse forms need to come down and a new structure built

  • We discussed the possibility of doing static engine testing at NASA Ames
    • It would take contact with (and the likely intervention of) Center Director Pete Worden, but that might be possible.
    • We should probably not approach him until we are ready to do some actual testing.
    • Stewart C volunteered to take part in a “Notional” committee to initiate when, assisted by Michael W.

State of Engines

  • Dan showed some preliminary lathe work on an Inconel 718 catalyst-pack base
  • Temperatures within the cat pack are expected to be about 1300K, much hotter below, thus necessitating Inconel

State of Vehicles

  • The mockup shown at Maker Faire has been stored at Stewart’s place
  • Dan discussed the possibility of flying the K.I.S.S. vehicle again, for practice/experience
  • Possible improvements (for K.I.S.S. IV) might include:
    • higher tank loads (previous flights were just 1 gallon of 85% HTP)
    • higher HTP concentrations with newer cat packs
    • constant pressure option (vs. the “blowdown” used previously)
    • stronger fin attachments to support Mach 1+ speeds

Old Business

    Bylaws update

      Michael Wallis and Gerald Nordley are still working on getting an updated document put together.

New Business

  • Possible new meeting sites
    • Michael Wallis mentioned the Denny’s at Mathilda and 101
    • Julie mentioned Hacker Dojo
    • There seemed no immediate reason to change.
  • Michael mentioned preliminary work on a wiki for the group has been done and content is needed
    He’ll try to move content from older versions of the web site to the wiki.
