December launch cancelled

December 16, 2017

Last night, the forecast looked decent for today. This morning is now showing a cloud deck of 1000 - 2000 ft. all day. More snow is expected tomorrow so we are canceling the launch. president bob

December launch

December 2, 2017

We are aiming for one last launch opportunity this year. Goal is one day of the weekend, December 16 or 17. The reason for 2 date options is to allow for weather. A final decision will be made during the week prior. Low clouds, wind, rain, or snow are criteria for canceling. Also, field conditions (mud/snow). Daily status updates will begin here at T-1 week. Marty Weiser will be your launch director. president bob

Next launch November 5

October 14, 2017

We are currently aiming for launch on Sunday November 5'th. Marty Weiser will be your launch director. Still too early to guess at the weather. Daily status updates will begin at T-1 week. President Bob

Marty Weiser launch report

June 4, 2017

We didn't advertise the launch as WheatChex, but with 16" tall wheat in June, I figured it would be nice to revive the name. It was a great two days of rocketry supporting four different youth groups ranging from cub scouts to college kids. Friday 6/2 was set up for roughly 100 5th graders from Midway elementary in the Mead SD. SPARC president Bob Yanecek has been working with the teachers from well over a decade to teach some rocketry as part of the science curriculum and have the students build and fly variations on the Estes Alpha. There were 113 5th grade flights on motors from A through D with most flights being on C and D motors. Bob obviously instills the small rocket - big motor philosophy we see in his efforts. I am surprised there weren't any Es. There were a couple of high power demo flights on H & I motors for the kids during the day from both SPARC stalwarts and HS students from Riverpoint Academy which is also in the Mead SD. After the 5th grades left, I stayed on and supported a couple of more Riverpoint flights including two NAR Jr. L1 certs. Saturday was another great day of flying as a lightly advertised public launch. We hosted Cub Scout Pack 351 from the Spokane West Plains and students from the EWU Rocketry. The Cub Scouts had built Quest Starhawks and flew them multiple times A through C motors. They appeared to have a great time and enjoyed the models that were given away after midday by some folks that were clearing out their fleets. The more public aspect of the launch resulted in some midpower flights to go with the low and high power flights seen on Friday. EWU Rocketry had about a dozen members on site - most were focused on the test flight of their capstone project which is a boosted dart, but a few were doing L1 certs and additional flights of their L1 rockets to gain experience. After multiple ground tests of the deployment charges and some fussing with the booster to dart transition the boosted dart had a successful launch with full redundant dual deployment in both units on a J800. Pictures and later this week data can be found in the EWU Rocketry Facebook page. The launch was lightly publicized since we had some issues in posting to both the SPARC website and the SPARC Facebook page. One has been resolved while there is still work to be done on the other. However, that was not the only technical difficulty. There was some confusion in dealing with the FAA in Seattle that resulted in the launch being listed as having a 20 mile radius cylinder rather than a 0.5 mile radius cylinder 20 miles north of GEG. Fortunately, we were low enough and Spokane TRACON had the information right so they could handle the air traffic until the misunderstanding was sorted out. Special thanks to Bob Yanecek, Alan Roberts, and David Glass for everything they did on both days to make this a great SPARC launch to end the spring season. The flight stats are listed below and the total impulse was about 7000 N-s or the equivalent of about an M1600. Marty

Dave Glass launch report

May 14, 2017

Yes, a bit of wind, but it was gratifying to see precipitation all around us but not on us. I had three good flights; Li'l Dude on an F20, Crash Test Dummy on an F32T, and Bruce, a Batman-themed rocket, on a G74. The Harrington Water Tower had a great up on an E20, but the wind had it in a downward trajectory after burnout. The air pressure on the large, relatively flat top prevented ejection, and that was that for the tower..... I scored the second-most-exiting flight of the day with Freddie the Freeloader, my boosted dart. After two cato's of H550's, I lit the tried and true (up to this point) I357. For an as-yet-to-be-determined reason the eject charge blew about a second after burnout, stripping the chute and core-sampling the booster. Fortunately the dart had just separated and continued its journey to 1700+ feet, deploying the chute for a gentle landing. First place for exciting flights of course goes to Rob Emanuele, the only rocketeer I know to have both a sparky liftoff AND a sparky landing! (hmmmm, I detect a nickname in the making ;-) ). Rob, let us know how things turn out; despite the jokes we hope it works out OK..... Good turnout, manageable weather, and no GSE glitches that I noticed. Thanks to Alan and all who participated. David (the one who's sorta walking ;-) )

David Powers launch report

Because of carousing from winery to winery with a friend from Seattle the night before, I didn't arrive until 11:00 and only got three fights up. However, for a change, all three were perfect flight and except for the long walk recovered all three without hours of searching...maybe I should carouse more often. I started basic to get my feet back on the ground with the Mean Green machine on an E9-8, followed by my Jay Hawk on a G79-10W...during the recovery of which I missed Rob's excitement. My final launch was my 24mm reverse fin, now renamed to the simpler "Backup". I finally got the Rocket Models back to Mark...sorry it took so long. Thank you Alan for a fun launch (and the spirit of Joe for keeping the rain away)... those who launched and inspected rockets. It was good to see everyone and to meet some new enthusiasts. David...the one still walking...so far.

Alan Roberts Launch report

Well the weather cooperated. Rain showers avoided us and the winds while brisk at times were manageable. We had a great turnout with lots of new faces which I always find exciting. New faces are the lifeblood of a club and I sincerely hope that many of those new faces become old friends as we share the rocketry bug. We had 21 flyers put up 48 rockets using 51 motors (there were no engines other than those in the cars that people arrived in). We covered the spectrum from 1/2 A thru I with a total impulse burned of 4,488 NS (I use average for each motor size). We had 8 L1 certification attempts of which 7 were successful. I believe that those all came from Marty's students. Perhaps one of the "old timers" will know if that is a record number of L1 certification attempts at a SPARC launch? Mark Howe had the most flights with 7 a couple of which involved gliders that performed quite nicely even in the stiff breeze. Rob Emanuele burned the highest collective impulse (again using average motor thrust) with 971.25 NS. Rob also had the longest time aloft on his last flight of the day at around 5 hours. Rob has to give an assist to Avista and their power lines for that feat. I watched it thru the binoculars and have to say that it was quite the flash of light when his rocket hit the power lines. Personally, I finally got my Jolly Logic Chute Release to work properly. The first flight was in a LOC Precision IRIS on a G80 Blue Thunder. Perfect straight boost with deployment of a reefed main at 2,101' AGL apogee. The JL Chute Release un-reefed the main at 600' for a perfect flight and recovery. My second flight with the JL Chute Release with a Binder Design Dragonfly on a H97 Black Jack. This rocket has flown nicely on this motor in the past. Unfortunately this time it weather cocked quite a bit which really reduced the altitude (only 1,100' AGL). This had the secondary effect of making the ejection delay too long for the flight with deployment only slightly above the 500' altitude that the JL Chute Release was set for. It all ended up fine but made for a few tense seconds. In hind sight (we seem to use a lot of that in rocketry) I should have used a faster burning motor for the wind conditions to get the rocket off the rail at a higher velocity. Our next SPARC launch is scheduled for Friday, June 2nd with the Midway Elementary School Kids followed by a full SPARC launch on Saturday, June 3rd. Don't forget that FITS will be over the Memorial Day weekend in Mansfield. Thank you to everyone that came out enjoyed the day of flying. Alan
