Erroneous report principle secratary. Exalted rubles per support exacting renumerative penalty scourging eversole rick's pun soliloquy. :)

Much work on them remains to be done: scanning >the originals that didn't translate to Word the first time, cleaning up >noise, tracing the graphs in Illustrator, adding legends, callouts & >captions to figures, and adjusting sizes. The text, as previously noted, is >fully digitized. > > Preparation of the ERPS 2003 Data CD-ROM was discussed. >Chris requested Kevin to make up a list of his proposed contents, so that >we can better organize next year's effort. Kevin agreed to do this. > >INFOTECH >-------- >Sean Lynch > > None of our servers has been compromised within the past >month. However, we (or more properly our ISP, Hurricane Electric) was >recently -- for reasons unknown -- blacklisted by Osiris (sp?). This has >now been resolved. > >LIAISON & PAO >------------- >Michael Wallis > > Several members were privately e-mailed by someone outside >the U.S. asking for details on peroxide purification. The consensus was >that such inquiries should be re-directed to the public mail list, and >answered there (if at all) only with a warning that any attempt to do this >holds hazards for the inexperienced -- which is precisely why such >processes are not described on the Web. > > Randall noted that one Richard Speck fired a rocket fueled by >alcohol and HTP in Colorado. He survived. (This is another potentially >hazardous activity, since alcohol and peroxide form explosive mixtures.) > >LOGISTICS >--------- >Sean Lynch > > Nothing to report > >TREASURER >--------- >Michael Wallis >Chris Winter > > Chris reported the current balance. No funds were disbursed at >this meeting. > >CHIEF SCIENTIST >--------------- >Kevin Bollinger > > Kevin showed a vortex chiller made by X-Air that can drop >temperature by 150 Deg. Celsius. > > He offered to sacrifice an engine for development of cat packs >and test of cermet catalyst. This would have some >ports drilled into it that would render it unusable for flight. > > Another need is to find better ways of making pellets from the >cermet catalyst. A combustion chamber is a rather severe thermo- >acoustic environment, where poorly bonded pellets will disintegrate, >heading south with the exhaust plume -- and the performance of the >rocket. > > Kevin requested a small amount of max-concentration HTP for >tests of hypergolic biodiesel propellants. He will need this in one or two >weeks. > >FLIGHT CONTROLS >--------------- >Bill Clawson > > Due to the Hallowe'en holiday, no FC team meeting was held last >week. The next meeting is scheduled for 14 November. > > At the previous meeting, some progress was made on software. >The snubber diodes are on hand, and data on the ADXRS150 gyro chip >(presented at the meeting) indicate this will do the job for us. > > Bill described Gizmocopter for our two visitors. > >PROPELLANTS >----------- >Pierce Nichols > > Pierce and Dave M have finished welding the structure for the >sparger. It was reliably reported that the pockets of blue language >trapped by cobwebs in Pierce's garage have largely dissipated, and local >BLL (Blue Language Levels) have dropped to acceptable concentrations. > > Some assembly remains to be done on the sparger. > >REGULATORY >AFFAIRS >------- >Randall Clague > > Pierce has a hard copy of the shipping papers for the peroxide he >will be transporting. We plan to comply with the hazardous materials >regulations for this transport, though we are not legally required to do so. >Having a printed copy of the shipping papers in the cab of the transport >vehicle is part of this. Another part is placards and labels. > > For the flight tests, we will have a waiver to 50,000 feet. Expected >ceiling for the vehicle is 11,000 feet.

The engine delivered 95% of desired thrust. The shortfall was >laid to the presence of a 90-degree elbow which added some extra >pressure drop. This elbow is not part of the flight configuration. > > Despite all efforts, the Dataq data acquistion system failed to >respond. Data were taken from the backup system, which consisted of >two LCD displays showing tank pressure and chamber pressure.

Setup is >planned for Saturday and flights for Sunday. Current plans (which may >change) are to do two flights of KISS-III, with 4-liter and 7-liter propellant >loadings, and to fly a solid motor. Due to schedule pressure, the 10-liter >flight of KISS-III is postponed until our next opportunity. Observers will >travel down on Saturday. > > Forecasts indicate that weather at Mojave is improving slowly. >Saturday is expected to be partly cloudy, with winds of 20- 30 mph. >Sunday should bring gentler winds. > > Denny's in Mojave is the assembly point. Setup team is to meet >at 10 AM on Saturday. Flight crew and observers meet at 7 AM on >Sunday. > >SMARTFLIGHT >----------- >Dave Weinshenker > > Dave W and Sean have gotten the microcontroller to respond to >keyboard commands. The purpose of this system is to collect flight data, >store it in on-board non-volatile memory, and also broadcast it to a >ground station via amateur packet radio. It will include a beacon function >to assist in recovery operations. > >Spike >----- >Sean Lynch > > A design meeting was held last week.

A lengthy discussion was held, and various concerns were >brought out. The bottom line is that we need to identify and contact >whoever has authority for oxidizing propellants at Ames. Gerald Nordley >agreed to continue to act as liason with Ames, and to identify this >responsible authority in concert with the visitors. > > >Meeting #247 adjourned at 10:05 PM.
