DOCUMENTATION
-------------
Chris Winter
Chris still needs more familiarity with CVS before he can merge
his Phase 1 update of the ERPS Web pages with the database. Michael
will provide some tutoring at his convenience.
Rick has completed scanning the Rocketdyne document, and
has OCRed parts of it. He presented copies of this material to Chris on
CD-ROM. They can now split the work, and it should go faster.
Work remains to be done on the brochure. Also, designs for a
letterhead and business cards have been requested. This should all be
done in time to be printed up for WorldCon. Chris will see to it. Michael
will provide a sample letterhead used in the past as a guide.
Chris tested the ERPS CD-ROM in his laptop, this time using a
standard CD-ROM drive instead of the DVD-ROM drive. The disk was
perfectly readable.
LIAISON & PAO
-------------
Michael Wallis
Our ConJose (World Science Fiction Convention #60) party room
in a suite (with one of the two bedrooms also reserved) at the Fairmont
Hotel for Sunday night has been confirmed. Funding for drinks (soda,
beer) and snacks was approved. Anyone wanting to help out can contact
Michael after the meeting.
We have proposed an ERPS panel. Possible openings on some
of the space and technology panels also exist, but no firm time slots
have been reserved for us yet.
The California Space Authority will be sponsoring a conference,
International Satellite Communications, in Long Beach on August 27-29.
LOGISTICS
---------
Sean Lynch
Nothing to report
TREASURER
---------
Michael Wallis
The treasurer's report was presented and accepted.
Expenditures for the following items were authorized at a board
meeting just before the general meeting:
KISS construction
POGO
Gizmocopter
Additional H2O2 supplies
Sparger development
A filament winder prototype
Purchase of a high-pressure tank from XCOR.
CHIEF SCIENTIST
---------------
Kevin Bollinger
Kevin showed parts for the prototype winder for filament-
wound pressure tanks which he will be constructing.
FLIGHT CONTROLS
---------------
Bill Clawson
It has been determined that the "Disk On Chip" device is useless
for our purposes. We will substitute another form of solid-state memory.
The BASIC Stamp is also unsuitable. Because of overhead, it
cannot maintain the refresh rates needed on the four PWM controllers
while doing the other processing required. Sean and Dave W have
hardware that will program PIC microcontrollers, and will determine
whether one of that family can replace it
Nate Dietrich reported that the new motor he ordered should
arrive in a week.
PROPELLANTS
-----------
Pierce Nichols
Kevin has obtained peroxide quotes from the local Solvay Interox
distributor. He will print out the prices and spec sheets for the five grades
they offer so that a purchasing decision can be made at the next meeting.
Existing stocks of peroxide are maintaining their concentration
very well.
REGULATORY
AFFAIRS
-------
Randall Clague
Dave W reprised his report on the legality of ERPS transporting
H2O2 in California.
Randall will forward a summary of our research on this question
to Mark Holthaus (sp.?).
SAFETY
------
Dave Masten
The state of safety remains good.
TESTING
-------
Dave Masten
Further progress in testing awaits repair of the water system at
the ranch. A BBQ at the Ranch will happen two weekends from now.
Watch the E-mail list for details.
SMARTFLIGHT
-----------
Dave Weinshenker
No launch opportunity exists at Fresno or Livermore during
August. There is an event called Hayburner at Paso Robles, and XRPS
will take place at Black Rock at the end of September. Contact Dave W
for details.
KISS
----
Mark Blair
The design of KISS-III was frozen at the recent KISS meeting.
Parts have been ordered, and many are on hand. An assembly meeting
will be scheduled when sufficient parts have arrived.
Spike
-----
Sean Lynch
Nothing to report.
POGO
----
Dave Masten
Completion of Gizmocopter is the pacing item.
Our contract machinist is waiting for a sample of the alloy we
plan to use for the engines, so that he can estimate the difficulty of
making the parts we need.
Dave M reported that the mass budget for the vehicle appears to
have more "headroom" than it did previously.
Meeting #241 adjourned at 9:07 PM. The next meeting is scheduled for
Thursday, 15 August 2002.
The treasurer reported final pun tallies for several meetings, including this
one, resulting in cash receipts of $10.25, $6.25, $9.50 and $14.50
respectively. At his first opportunity, he will pool and count these funds
and deposit them with a credit line to the Spike project.
Respectfully submitted,
Chris Winter
Secretary, ERPS
+++ PLEASE ADVISE THE SECRETARY OF ANY ADDITIONS OR
CORRECTIONS TO THESE MINUTES +++
