Meeting Minutes March 2005

March 27, 2005

The club meeting was held on March 26, 2005 at HobbyTown a the north division Y. In attendance were Bob Yanecek, Harold Kellems, David Stubbs, Marty Weiser, Jim Kurilich, Ray Stoner, Krys Davidson, Mark Howe and Terry Morre-Read.

The agenda was as follows;

Treasury report
Buying a Port-a-Potty
Raffle report
Club Outreach report
Sport Rocketry Magazine discussion
Club Project flights
Finishing Club Project
Membership Card

We put Bob on the spot and ask for an impromptu treasury report, as he was unprepared (our fault, not his) the report was slim on details and only estimates on monies in the bank. Paid out for the club were Club NAR dues of $40 and received a 1/2 a bill for the March Port-a-Potty rental. The club received in $145 in club dues (and launch fees) at the last launch. Bank balance is somewhere around $500.

The Port-a-Potty purchase was again a topic of discussion. The cost of the Port-a-Potty was about $100 more than anticipated, $250, so we needed a club decision on the purchase. It works out that we pay $55/month for rental, service and delivery, and would only pay $25 for service if we owned one. Running the numbers for the year indicate that the cost of ownership would be repaid in about 8 launches, so the decision was made to purchase a Port-a-Potty post haste. We are going to make the purchase from American On-Site Services because they include a soap dispenser in the cost of purchase. The other places don't. Ray and Krys will take the task of making the purchase prior to the next launch.

Jim Kurilich gave a report on the progress on the raffle for the motors for the club project. He has send 40 snail mail letters to 40 different vendors requesting items for the raffle. He has received no responses as of yet. He mailed most of the letters this week. Thus far we have had donations to the raffle by club members and Puget Sound Propulsion. The donations include Two Estes kits by Mark Howe, an Edmunds AeroSpace Deltie Airshow by Ray Stoner, a customer mid-power kit by Marty Weiser, lathe time by David Stubbs, 29/120 motor hardware by Puget Sound Propulsion, and an Alpha III kit by HobbyTown. Donations are brisk. It was decided that each item will be raffled off individually with prices set in based on the value of the item raffled. Prices will be either $1 or $5. We have red raffle tickets already, and Bob Yanecek will purchase another color prior to launch. An announcement of what will be in the raffle for the April Launch will be made approximately 1 week prior to the launch.

The outreach program is going well, there is a lot of activity related to it taking place. Mark Howe is coordinating this effort, so if you hear of anything, send him an E-mail. Current activity includes (sorry if I missed any, it was hard to keep up in my notes, let me know what you are doing and I'll edit.)

Mark Howe is working with the school at Moran Prairie
Bob Yanecek is working with Midway Elementary
Marty Weiser is working with McDonald Elementary 4H
Marty Weiser is also working with the TARC team at Cd'A High School
Jerry Buckles and John Hearn are working with the Garfield 4H group
A flyer is at the Division White Elephant

Past Activity has been

Marty Weiser and Ray Stoner worked with Adams Elementary for a 1 night Science fair
Mark Howe worked with the school at Moran Prairie
Bob Yanecek worked with the school he has been working with
Jerry and John worked with the Garfield 4H

Future Activity

Place Flyers when we receive them or print them from the website and distribute.
A scouting assembly day at Michaels on the 19th of April.
Newspapers will be contacted for placement of ads, and community events listings
TV stations will be contacted for "human interest" stories and announcement of "your weather" for the club
Inquiries about a possible Mall display
Inquiries about a possible display at the PX at Fairchild AFB
Marty and Ray will coordinate a TARC test/qualifying flight in April

The club has the opportunity to receive 40-50 free Sport Rocketry magazines for the cost of shipping only, the decision was made to proceed with this. They will be distrubed at club launches.

The club project, a 1/4 scale Nike Hercules, need to be complete prior to flight, the major items for completion are; Electronics wiring and installation, Recovery system installation, Rail button installation and some slight finishing activities that are optional. The rocket will be transferred from Mark Howe's house to Ray Stoner's house for final completion.

The decision was made to fly the sustainer on a J570 load (?) at SPARC at the May Launch, the complete rocket in two stage configuration with 5xJ3500 loads at Mansfield at the "Fire in the Sky" launch in late May, and at LDRS in full two stage configuration with bigger motors as yet to be determined at LDRS in Lethbridge Canada in July.

Currently David Luders has donated 2xJ350's to the project, Marty has donated undisclosed motors, but the balance of the motors will either be donated, or purchased using the raffle funds. Final motor configuration for the LDRS flight will be determined based on the amount of money raised and donations received.

A membership card was discussed, and we decided to proceed with creating a card for each paid member of SPARC, and their families. Mark Howe will design and print the cards.

Next months agenda includes a build of rocket gliders led and donated by Mark Howe, THANKS Mark.

March 2005 Launch Statistics

March 16, 2005

March 2005 was a bit larger than normal one-day launch for SPARC with 105 flights as Ray reported. We also reached a milestone of 2000+ recorded flights (since July 02 when I started keeping detailed records). There were a total of 125 motors used and the total impulse was 8,833 N-s (mid-sized M) and the average impulse per flight as 86 N-s (small G). The statistical details and along with additional comments about the graph are included in the extended entry. 05Mar motor summary.jpg Here are the detailed statistics for the March 2005 launch. Impulse Number 1/2 A 2 A 8 B 26 C 34 D 18 E 8 F 5 G 6 H 6 I 9 J 1 Unknown 2 Total Motors 125 Total N-s 8,833 Motor Equiv. M Ave N-s/flt 86 Motor Equiv. G 2 Stage 5 3 Stage 1 3x Cluster 5 4x Cluster 1 Total Flights 105 Total known flights 103 Motors/Flight 1.19 The motor use profile was quite typical for SPARC except for the distinct bump for the I impulse and perhaps a slight weakness in the F - H classes. I am guessing that this was a result of a combination of decent weather an an on-site motor vendor. This month I calculated averages for the one and two day launches so I could compare them to this month's launch. We launch 90% more rockets during a two-day launch than a one-day launch (159.5 vs. 83.8), but only increase the total impulse by 48% from 7,087 to 10,490 N-s. The implication is that that the HPR fliers launch the same number of rockets regardless of one or two-day status of the launch, while two-day launches attract more model and mid-power fliers. Marty

March 05 launch report

March 14, 2005

Saturday was a great day for a rocket launch. It certainly didn't look like it at the beginning of the day though. Winds were higher than we like and it was pretty cold outside.

In-spite of that there was already several cars on site, along with the trailer at 0900 when I arrived. All on site were talking about the wind and the cold until about 0915, setup began! More cars had arrived and the scouts were there, so setup was very quick and uneventful.

At 1003 the first fliers meeting (Mark Howe the VP did a GREAT job) of the season was underway, and I think it was the most attended fliers meeting we have ever had at the beginning of a launch. There were lots of familiar faces, and lots of new ones too. There was quite a crowd. It set the tone for the rest of the launch.

Following the fliers meeting, Ray called in the waiver and launches began. Models were the first up, as usual, and it was a good indicator of the wind conditions we were to see for the next couple of hours. It was amazing the number of people on site, the words "Range is open" drew a hoard of rocketeers to open pads.

I was inundated with curious Rocketeers that had tons of questions for me, as a result I didn't get to fly too much. It was very cool that there were so many interested in what was happening and the rockets.

I flew "Charm" on a smaller motor than I had intended due to wind, but by the time I got to the pad to load it, the winds were almost calm. I coulda put a bigger motor in it. The winds stayed that way and the high power along with the mid and model pads got good use as a result.

Flights were brisk and continuous through out the day, lots of model flights, a good number of mid power and the high power racks seemed to be full all day. I think that Puget Sound Propulsion being on-site contributed significantly to the number of high power flights. It was VERY nice to have a vendor on site again. Let's hope they return with a fresh stock of motors! Last I heard they hit their target dollar figure to break even for the launch.

Flights continued until around 4:15 and I think there could have been more, but all at the site were worn out. So tear down began.

Again, there was a good number of people that helped, so tear down went quickly. On behalf of the club I want to thank every one that helped out on the setup, tear down, LCO duty, RSO duty, getting waivers signed, and a very big thank you to Puget Sound Propulsion.

Some limited stats for the day. Marty will post more complete stats in the near future.

Total of 105 flights
16 High power flights
Neil Anderson topped the charts with 6 high power flights.
Most of the high power flights were "I" motors.
One level 1 certification on an H242 (congratulations to Lou Bragg)
One level 2 certification on a J350 (congratulations to Neil Anderson)

Don't forget the club meeting on the 26th at 10:30 am at Hobby Town, there will be a presentation on how to file for a waiver on the agenda.

Now here are some comments made by Mark Howe and Bob Yanecek, I'll just copy them in...I was just to distracted by all the questions to get more than a fuzzy memory of the launch.

Mark said;

The first SPARC rocket launch of the 2005 season took place today. Hereis a brief recap from my perspective...

I arrived at the site about 10AM (had a rough night, but I'll leave it at that). I was pleasantly surprised to see at least dozen cars already on the flight line, and everything set up and ready to go. We held the fliers meeting, and noticed lots (and I mean LOTS) of new faces mixed in with the regular crowd. Conditions were partly cloudy, temp hovering around 50 degrees, but it was a little windy. The motor vendor from the Seattle area was on-site...how nice it was to finally have an on-site vendor again! I hope they made enough dough to make it worth their while, and hope to see them at future launches. A troop of Boy Scouts was on-site with a ton of models. I heard they gave a lot of assistance in setting up the GSE for the day. Many hands make light work! Ray called in the waiver, and I think the first bird took to the air around 10:30. I performed a majority of the LCO duties (and some RSO duties) for the day. We did have a couple of first-time LCO's: Bob Yanecek, Jim Kurlich, and Jeff Halstead. It's nice to see more people getting involved in the operational aspects of launch day, and their performance was very noteworthy.

Personally, I have both good news and bad news to report. The bad news is that I only launched 5 out of the 15 rockets I had prepped for the event. The good news is that means I have 10 rockets all ready to go for the April launch! I had two "first-timer" flights, both were less than optimal. My Estes "Outlander" (with shock absorbing landing gear) was pretty pathetic on a C6-3, and hit the ground nose first before popping the chute. Unfortunately, the shock absorbing landing gear only works if the thing comes down "feet first"! Amazingly, there was no damage. As I was building the kit I really thought it should have a 24mm mount instead of a 18mm one. Next month I'll launch it on an AT 18mm RMS D13-4 motor, and I expect the results will be much better.
Next up was my new Quest "M2Q2 Lifting Body" on a B6-4. There was a
loud "bang" during the ejection charge, and the rocket spit the engine and came in nose first. Post flight examination showed that I had packed the recovery system too tightly, as the parachute (still rolled up) was only sticking half-way out of the body tube. When the engine spit it took the engine hook along with it, so some repairs are in order. At this point I was a little dejected....two flights with two "failures"...nowhere to go but "up" from there!

The wind died down a bit, so I yanked out my Edmonds "Gemini Thunder" (2gliders) which went up on a D12-3. Finally I hit it right! Great
flight and simple recovery...although I did have to walk out to the same area twice because I didn't realize both gliders landed in the same approximate area...(I was only tracking one of them). Next I popped off an Estes Turbo-Copter on a 1/2A. The nose tumbled more than helicoptered back to the ground, so some tweaking of this rocket is in order. Saving the biggest for last, I put my LOC Expediter up on a AT 38mm RMS I154-J. Sims showed that the apogee would occur about 8 seconds after burnout. Unfortunately, this put ejection right in the middle between a "short" and a "medium" delay. I opted to use the medium, and held my breath (along with most of the crowd) as the parachute ejected well after apogee. No zipper, no damage...good thing I use loooooong shock cords!

I believe I used the smallest engine of the day (with the 1/2A), and
also one of the larger motors (with the I-154). I think there were only 2 or 3 "J" powered flights, but won't know for sure until the flightcards are reviewed and the data posted.

We had at least one L1 and one L2 certification flights, (both
successful), but I may have missed one or two. Congratulations on your accomplishment...get ready to spend some big bucks on those BIG
motors!!! I also think we had at least a dozen (probably more) high
power flights.

The model pads were kept busy throughout most of the day by the scout
troop, and a few other families. I can't recall the name, but towards the end of the day somebody had at least 5 rockets on the model pads, all for one round...how he kept track of where everything went I'll never know. Very few mid-power flights were attempted, but there were a couple F & G flights.

The majority of the flights were successful, but there were a few separations, faulty chute deployments, and ballistic entries as well.

Tear down started about 4:15...thanks to everyone who helped to pitch in with both set-up and tear down. As I noted earlier, many hands make for an easier work load.

It was great to see all of the new faces, the "regulars" (Harold K,
Keith S, John H, etc...), and even a few people who were "missed" last year (the Jopson's).

Bob said:

I'm home now and the trailer is unhooked.
Slowly the blur of the day is developing into memories.

What a rush March, great field conditions, clear blue skies, unlimited visibility... it was like a dream.

I arrived a little before 9 to a lone truck in a howling breeze. 1 white hairy face shrugged and wondered if "we could launch in this?"

Then cars began showing up and the blur began

There were scouts with rakes smoothing out the areas around LCO table
and pads.

People everywhere saying; "What can I do?"

By 10:03 everything was set up and the first fliers meeting of the season was underway.

Launching began immediately with models getting a hang of winds aloft
and drift issues.

The words "Range is open" drew a hoard of rocketeers to open pads.

We had an on-site vendor for the first time in way too long.
Puget Sound Propulsion. They didn't just sell, they flew too. A poorly painted (OK not painted) Saturn that flew beautifully. 3 D's to 1 E fatboythingy that was spectacular, would have been awesome
if all 3 E's had lit. They were smiling as they left and threatening to return next month.

By late morning the wind gave a wonderful pause that lasted for hours.

This has to be a dream.

We were finding more rockets that were being launched. Marty's long time gone 38mm min diameter fin can that came in South was really Southwest. Found a 54mm plastic N/C west/southwest with just a tad of color on the tip. Both had been 'tractored' . Found that my 18mm fin can which had been hanging in a tree for 2 years was down. Still waiting for the N/C - parachute. Found a nicely finished Alpha that looked fresh. I'm guessing a scout didn't search hard enough.

There was TONS OF SUN.

Several calls for "last rack" were met with booooos and nonotyet

So, launching continued while the crowds slowly diminished.

The sun was just above the horizon as the last of the trailer got loaded and 5 vehicles made up the 'last train out'.

Special kudos to the Jopsons. Pretty sure they had the longest recovery which was in the middle of a bunch-o-cows way southwest.....aka downwind. Recovery was initiated with a knock on the door for permission to recover their rocket which was cheerfully granted. Nice public relations for the club.
