Well, there are good launches and bad. We finally had a bad
one. This was to be the weekend Chuck was attempting his Level III Certification
flight. Chuck had built a beefed-up RDS North Star for his Level III rocket
figuring that it would cost less and is a proven design to build upon. As I
arrived at Chuck’s home in San Diego late Friday, he was applying the final
coat of paint. (No matter how much preparation you do, there are always things
that need to be done the night before the launch (You’ll find this out when
you do your certification flights!) Chuck walked me through the details of the
rocket: deployment, motor, etc. Every thing looked rock-solid.
We didn’t need to rush out to Ocotillo in the morning because the
rocket was scheduled to fly on Sunday morning. Therefore, we took our time to
make sure everything was right.
We arrived out at Ocotillo mid morning on Saturday. Winds
were about 15-20 with gust up to 40MPH. There are times when the wind dies out
completely, however, it starts right back up again; frustrating. Someone send
God an email, and tell him to cut-it-out! Saturday was so hot everyone just
hung-out under their tents. Other than Andy Woerner’s 1/3 V2 rockets (see
picture on right), Chuck had a hit with his misting system that he designed and
built which we installed under our canopy! Using the standard misting system
nozzles and some rubber hose, Chuck hooked the hose up to a bug sprayer, which
would hold a charge for about ten minutes. This dropped down the temperature
down from a million to 999,980 degrees!
As night approached, we
anticipated the firing of a flare charge that I found out at Delamar dry lake.
The kids kept finding these electrically-charged firing mechanisms that
connected to the flair. Andy Woerner installed an igniter and launched it. Wow,
it lit-up like a star for about three seconds. Cool. After exhausting all of the
kids’ mortars, we went to bed. Man that wind. All night long we encountered
25-40MPH winds. The next day's launch seemed doomed. Then about 5:30 in the
morning it broke. The wind dropped down to about 5MPH with gust up to 20MPH. (I’m
so tired talking about winds at launches!)
Chuck and I started to prep his
rocket: Install Lunch lugs, pack shoots, sand nose cone, arm electronics, and
build motor. Ok, carry it out to the pad. Thanks to Andy Woerner’s pad we were
ready to launch on the M1315. We had just received our Pretto Bros. Rocketry
shirts and we had a large contingent of family there to watch the launch.
5-4-3-2-1- Lift-off. She flew great! Arched over and a POP - white smoke!
NO CHUTE…We witnessed the rocket come down with the nose cone ejected and NO
CHUTE. After wiping the tears from our eyes we walked down range to do a post
mortem. Although both 7gm charges fired, (Primary & Backup) it failed to
deploy the chute. It is difficult to determine if the chute got stuck or we didn’t
have enough charge!
The upside of this report: I was about 60 miles out side of
Las Vegas (on my way home) when I heard from Chuck: “I have my next design
ready!” Persistence is the key to success. Not only with rockets, but also in
any thing you do.
