events this week

Jonathan Sivier
 

There are several events this week. A couple are official club activities and a couple are events that some club members are going to and other are invited to join us.

On Tuesday, October 8 some club members are planning to go to the movie Ad Astra. We will be meeting for dinner at Dos Reales on Prospect at 5:30 and then heading to the 7 p.m. showing of the movie at the AMC 13 theater. Let us know if you plan to join us for either one so we can have room for you at dinner and/or look for you at the theater.

On Wednesday, October 9 we are planning to go to a showing of the movie "Chesley Bonestell: A Brush with the Future" at the Parkland Planetarium. This award-winning documentary about the "Father of Modern Space Art" explores Bonestell’s impact on America’s enthusiasm for space that began as early as the 1940s and grew into a national phenomenon in the 1950s and ’60s. His visionary paintings and illustrations in science magazines, books, and science fiction movies inspired and continues to inspire scientists, artists, architects, engineers, and sci-fi enthusiasts alike. The film is being shown only the one night at 7 p.m. Tickets can be purchased at the door and are $10 for adults and $8 for seniors, students, and youth. There will also be a free theremin performance before the film screening in the lobby of the Staerkel Planetarium by “Sea of Stars” featuring Gloria Roubel and Jason Finkelman from 6:15 pm to 6:45 pm. Plans for when to meet, etc. haven't been firmed up. If you think you would like to join us let us know and we'll send out a later announcement of details.

On Thursday, October 10 we are scheduled to help the group of kids we worked with on building rockets last week fly their rockets. This will be in Dodds Park starting around 12:30. We will probably want to meet there at around 11:30 to get set up. The exact location will depend on the wind as usual. The forecast isn't looking great, but we'll have to wait and see a bit later in the week to know if this will happen or not. If they can't fly this week we plan to move the launch a week to Thursday, October 17, same time and place.

We also our regular 2nd Saturday launch scheduled for Saturday, October 12. This will be held at the launch site in Rantoul. Once again we'll have to watch the weather to see if this takes place or not. Stay tuned for further announcements later in the week.

squatty body update

Gary Slater
 

Did the ground test just now.  


Using Mark Canepa's formula:  (7.5 x 7.5 x 5 x .006) + (4 x 4 x 14 x .006) = ~3.0 grams 4F.  I probably put in about 3.35 grams.  


I think in the formula the ".006" factor equates to a 15 psi if I remember correctly.  I don't remember stuff like that anymore, just the formula.  The two sets of factors are for the parachute bay + the volume between the nose cone CR and the forward MMT CR.  


SO! What was the result?


Blew that nose off, no problems; cut the 3 x 2/56 sheer pins (in place to prevent drag separation) AND pulled ALL the laundry out!  


As for a plus, I refolded the main so it fit better and put it in the nose parachute bay even tho the main will be closer to the fin can at full separation or extension of the shock cord.  Configuration will be nose- down 8 feet to drogue-down 8 feet to main-down final 8 feet to fin can.  Z folding and rubber banding the shock cord is something I like doing.  It certainly makes things a lot simpler putting it all together in that small space.  


I will try again tomorrow or Friday with a little less 4F.  Maybe. 


Thanks for everyone's input last evening.  




Re: swap meet on Tuesday #Meeting

Dear fellow rocketeers,

I deeply regret I will not be able to attend this function tonight due to a miserable cold that kept me home from work and then I wouldn't give to my worst enemy. I am very interested in any items you don't sell. Also interested in a big Brute that will Carney had for sale should he happen to a attend. I no longer have Will's email address if somebody could p.m. that to me I would appreciate it. Fortunately I only had a few buildable kits that survived the fire LOL. So anything you don't sell or swap at the Swap Meet feel free to contact me privately. I also understood the club had quite a number of biotic tubes for sale and I would be interested in buying any that are left over. My email address is jdbectec1@...

Maker Fest this Saturday

Jonathan Sivier
 

We will be participating in the Heartland Maker Fest this Saturday, October 5, at Lincoln Square in Urbana. The event runs from 9 a.m. to 2 p.m. We'll have a table with rockets on display. If you can come by to help out that would be appreciated. We need people to talk to the people at the event and get them interested in Model Rocketry and joining in our club's activities. You can bring some rockets to show if you have some you would like to display. If not just bring your enthusiasm. We'll be setting up starting at 8 a.m. If you can come and help out that would be great. If you can't come until later, come by anyway. Even if you just drop in for a bit later in the day. There will be lots of interesting things to see that other groups will have on display. You can find out more at

Here’s video of an extraordinary 2-stage amateur rocket flight at the recent Balls launch in the Black Rock Desert. P booster to O sustainer, 142,000 ft, Mach 3.66. And even so, there were factors which prevented it from reaching its much higher, planned peak altitude. 

 

The folks responsible for this flight are well known experts in many areas of rocketry, and continue to share their successes and challenges - adding a great deal of knowledge to the community. Note their names for future reference. (Jim Jarvis, Stu Barrett, Vern Knowles, Jerry McKinlay, Tony Alcocer, and more.) The voice of “Kate,” the Multitronix flight computer and tracking system, narrates the event.

Re: rocket building workshop on Thursday

Gary Slater
 

I can be there to help with that.

We will be helping a bunch of kids build rockets this Thursday, October 3. The plan is for them to then fly them next week on Thursday, October 10 (weather permitting).

The building session will be from 12:30 to 3:30 p.m. at the Grace Church, 800 West Oak Street, Mahomet. This is about 0.6 miles west of Division Street (where 47 heads south out of Mahomet) on highway 150 as it goes through Mahomet. The launch for next week is planned to be at Dodds Park.

We'll be helping around 90 junior high and high school aged kids build Balsa Maching Service School Rocket kits. We'll have glue and other necessary supplies to build the rockets, but bring any tools you like to have handy to help the kids. They will have several adults assisting, but we can always use any help we can get. If you think you might be able to come and help out send an email directly to me to let me know.

swap meet on Tuesday #Meeting

Jonathan Sivier
 

Our October meeting at the Springer Center is this coming Tuesday, October 1. The meeting starts at 7 p.m. The topic for this meeting will be our annual rocketry swap meet. Bring any items you would like to sell or trade. Even if you don't have anything to bring come anyway. Perhaps you'll see something that someone else brought that you would like. Of course, there will be plenty of time for discussion about rockets and other club activities.

Re: Go for #Launch

We are on the east side of the field, if anyone is looking for us.

At 11:00 AM, it was 74°F in Champaign, with calm winds and a clear sky.

 

Conditions are – at least temporarily – very good for flying, so we will meet as scheduled at noon at the Rantoul Aviation Center to begin setting up for our launch.

 

We’ll meet at the “usual” spot at the southwest corner of the field and check the wind conditions there before deciding whether to move to the alternate location on the east side. The current forecast calls for southwest winds through the afternoon. There is a slight chance of rain after 5:00 PM.

 

See you there!

Outlook for Saturday #Launch

Greg Smith
 

We have a rocket launch scheduled tomorrow, Saturday, September 28, at the Rantoul Aviation Center.

Setup will begin at 12:00 noon, probably (but not guaranteed - see below) on the east side of the airfield just inside the perimeter fence. Flying can continue until sunset at 6:40 PM. Our waiver allows flying rockets up to 10,000' MSL (about 9,250' from ground level). "K" motors are about the maximum practical on this field.

I normally check several different forecasts before each launch, but usually quote the "official" National Weather Service text in these messages. Rarely have the different sources disagreed so much or predicted such wild changes in wind direction and other conditions during a day:

-----

This is from the NWS:

Saturday - A chance of showers and thunderstorms. Mostly cloudy, with a high near 78. West southwest wind 6 to 8 mph becoming northeast in the afternoon. Chance of precipitation is 30%.

The Weather Channel says:

Scattered thunderstorms in the morning. Cloudy skies late. High 81F. SW winds shifting to NE at 10 to 15 mph. Chance of rain 40%.
(Wind NE 10 mph gusts to 23 mph)

-----

I'm not entirely sure what to expect, especially in light of that 180° wind shift from SW to NE right about the time we're scheduled to set up. This may make it difficult to decide between the two possible launch site locations on the Rantoul field. It's also possible that wind, rain or low clouds may interfere with our plans. (Note that TWC included 23 mph wind gusts in the detailed supplement to their forecast.) I'll try to stay optimistic until I post the final decision about the launch here shortly after 11:00 AM tomorrow. You can call me after that time at 217-840-1678 for an update.

Our next scheduled launch will be Saturday, October 12, also at Rantoul.

Here’s the latest chapter in Joe Barnard’s (BPS Space) rocketry engineering progress. I think it says a lot - not just about his great problem solving philosophy and innovation - but also our increasingly common access to advanced design and manufacturing tools. I don’t mean to say we’ve all for this at our fingertips, but so much closer. And he’s really got a knack for video production.
