ROC March 2003 Launch |
| Report by Robert H. Brigham
Lucerne Dry Lake Bed, California (RBP). After the great launch in February, some felt it was tempting the rocket gods to hope that conditions for the March launch would be as good, but they were. In fact, they were even better. Dok Hanson
pulling the Team Final Jeopardy (TFJ) trailer was among the first on the
scene mid afternoon on Friday. He discovered that there was actually water
in The new TFJ hybrid pad was set up, followed in turn,
by Joe
Mullin’s hybrid pad. Then we all headed into town for dinner. Many
of the regulars couldn’t make this launch, so it was a thin crowd that
spent the night on the playa. However, skies were clear, the last of the
breeze died away by Greg Lawson
and then Rick O’Neil, pulling
the club trailer, ambled in at dawn, and the range started to take shape. As the sun rose, the chill in the air gave way
to pleasant wind-free conditions. Rick O’Neil ensconced himself as LCO,
and the first rockets went up about The pace throughout the day was unhurried and there was
never much of a line at the RSO table.
In all 77 rocketeers (with associated groupies and hangers-on)
showed up to fly, but even though attendance was below last month, the
number of rockets wasn’t. Upwards (sic) of 200 birds flew on 231 motors,
most of which lit (take note, Dennis Dinga). Of these, 107 were AP, 121 BP and 3 were hybrids. Had all motors fired, total impulse expended
would have been 30892 N-s. This is half the value of the February launch.
Folks appear to be holding back the horsepower until SpringFest rolls
around. There were no M flights; the largest motor launched
was a L1150 by Chuck Platisa
in a modified LOC ‘Bruiser’, which Rick
O’Neil described as “Awesome!”. The smallest was a 1/4A3 in an Estes ‘Quark’ flown by
Andrew Atwood, which electrified the crowd,
coming in as a “lake stake”. The most popular motor this launch, by far, was the venerable
C6. A total of 56 were fired. This
accounts for the high number of flights but low total impulse for the
launch. Three participants tied for the lead with eight launches
apiece: Paul Newman, Joseph Contrevas, and Mr. “Control” Freak,
Bill Farr. Paul
flew four rockets on A10’s and C6’s, Joseph
flew a ‘Big Bertha’ and ‘Mirage’, all on C6’s, while Bill put up birds on everything from a 1/2A6 to an I284. That’s a
range of 1.1 to 586 N-s total impulse. Bill’s son, Brian Farr, was also busy, flying four rockets on a B6, D12, F21,
and F72. Right behind these front runners was Nicholas Eck who lofted 7 shots on B6’s and C6’s, and Mike Biggs and Matt Schneider, who each fired six rockets on big BP motors. The Trammel Clan,
Steve, Morgan, Alyssa, and Jon, together sent up 9 birds. Wrote the senior Trammel, “Alyssa Trammell
returned to rocketry after a brief hiatus intending to be a spectator
only. The first couple of
launches convinced her that she needed to rejoin the ranks of flyers (that
and a little purple Estes Rocket at RocketSilo caught her eye). She bought, built, and successfully flew both
an Estes ‘Freaky Flyer’ and Estes ‘Mini Meanie’, both on 1/2A motors.
Morgan Trammell caught the teenie rocket bug from his little sister
and bought, built and flew an Estes ‘Quark’ on a 1/2A. The surface of the lake bed was such that he
actually lake staked the Quark with no damage.
He preceded the ‘Quark’ flight with a successful flight of his
Estes ‘Bullpup’ on a C6. Jon Trammell succeeded in
the maiden flight of his 4” scratch built ‘Deimos’ on an AT G40-4. He wanted to build his 4” on the cheap so picked
up some “mystery” tubing and a “no name” 4” nosecone from a vendor we
had never seen before at LDRS. Airframe
and nosecone came to less than $20 bucks, fins and centering rings were
made from 2 plies of door skin laminated with epoxy.
The goal of the maiden launch was a low and slow flight which he
accomplished. For added effect
I used a coffee can full of starch packing peanuts to “manage” the recovery
system in the rocket; nice effect at ejection.I
managed a successful flight of my ‘Marginal’ rocket on an E9-8 from a
homemade curtain rod launch tower. It
appeared that the rocket reached the 3,000 feet predicted by RocSim. This is my improved version of the tower and
appears to have all the bugs worked out so if anyone needs a 40” tower
for 24mm and 29mm minimum diameter rockets just let me know prior to a
launch. I also flew a modified Estes ‘Comanche’ in a
D to C to C configuration. The
flight looked good but the second stage shed all it’s
fins (fiber glassed balsa) when the third stage lit.
Apparently the stage coupling was a little too snug and actually
blew up (over pressurized) when the third stage lit.
I got to end the day with a fun launch of a ‘Snitch’ on a D staging
to a C.” Kurt Gugisberg was back and having altogether too much fun with his
red flying fly rod case, nee ‘Gloomis’.
Using a rare redline I218, ‘Gloomis’ “went to 3203 feet
with perfect deployment at apogee with an Altacc”,
commented Kurt. Greg Lyzenga,
our man now famous in the annals of the Early on in the launch I sent up my 2.5” sounding rocket,
‘Matthews Marauder’ that contained a temperature sensor. Like the February
launch, I used a H180. I’m still refining the thermocouple mount; I get
apparent temperature fluctuations as the rocket rotates the thermocouple
in and out of the sunlight. This flight registered pretty much the same
pattern as last month, just 22 F warmer.
Surface temperature was 45 F warming to 53 F at about
700 feet AGL. From there the temperature dropped to 49 F at 1750
feet. A bigger booster is in the works so I can really loft the rig at
SpringFest. The highest flight of the launch was David Gates’ ‘Shredder, a minimum diameter 38mm rocket that went aloft
on a 6 grain Pro38 J360. It was
the only high altitude waiver flight of the day. Commented Erik Gates, “[Shredder] simmed to 9598' and was recovered just 300
yards away! That's how nice of
a day it was!” The lowest flight (of all rockets that actually cleared
their pads) had to have been Andrew
Fuller’s X30. It clawed it’s way to about 12 feet on an A8, and bounced back to the
lake bed before the parachute deployed.
Rumor has it that the actual instant of apogee was captured on
camera by someone at the flight line. Among the most interesting flight arose from a developing
ROC tradition of “upgrading” ‘Snitches’. One of the perpetrators of this
trend is David Gates who fielded
a ‘Snitch’ powered by three F20’s air-starting a G60. Besides the fact that the G60 never lit, the
F20’s didn’t perform as anticipated. The ‘Snitch’ tumbled aloft in a confusion
of smoke and flame, attaining an altitude of maybe 50 feet, before plopping
back to the playa – unharmed. David flew it again later (on the same
G60 that wouldn’t air start) for, as his Dad noted, a “Smoking Flight!” Another fun flight was the return of Dennis Dinga and his ‘Cluster 7’, this time sporting six D12’s and
an E9 using flashpan ignition. That’s
getting 123 N-s the hard way. The ignition was the most impressive part
of the flight. Dennis’ modification
of his earlier pan ignition system, while spectacular, was not as effective
as the previous arrangement. Most
of the motors did not light and the ones that did didn’t have ejection
charges. It made for a low and slow flight ending unceremoniously with
a belly flop on the dry lake. Another flight of note was Wayne Mrazek’s ‘ One of the interesting facets of rocketry that reporters
got to see at this launch was the Team
America Competition. Three teams made attempts to lift two raw
eggs to exactly 1500 feet. After
their trial runs of last month, Amanda
Wahlquist and the Bishop Amat
High School team weighed in with ‘Pyrotechnic’s Dream’. This attempt
used a F62-powered booster staging to an F40 sustainer carrying the eggs.
Unfortunately, the F40 didn’t light, which was bad news for the Bishop team. It didn’t do the eggs any
good either. Similar tragedy struck the The team from There were other reasons to celebrate at this launch:
Jim Hawk, Dennis Kielgass, and Peter
Rothe all joined the ranks of Level 1 rocketeers; Jim with a PML ‘Amraam’ on a H128, Dennis with a PML ‘Callisto’ on a H242, and Peter on a scratch build bird aptly named ‘Optimism’ which flew successfully
on a H123. The ranks of Level 2 fliers was increased by one: Eric Hanson sent up the same PML ‘Miranda’ that he certified Level 1 with last month, but this time he packed it with a J350. Reported Eric, “My two rocket buddies, Joe (More Thrust) Huber and Gary (Big Motors) Bitterman, encouraged me to go for my Level II certification at the March launch. I managed to get my Level I cert. in February with their support, and I hold their advice in very high esteem. They suggested that I use a AT J350 in my 3.5 lb. PML ‘Miranda’. I thought it would be cool to earn both my Level I and II with the same rocket. “The Level II process began ,on the morning of March 8th., when Greg Lawson graciously proctored and graded my written test. I passed with flying colors so it was time to visit my friends at RocketMotion and pick up a motor. I phoned them in advance and asked if they would bring a AT J350 to the launch. They were incredibly helpful and my motor was there waiting for me. “As I assembled my motor Joe and Gary kept smirking/smiling and me and saying ‘Your going to love this!’. A demented twinkle in their eyes. Our group of 9 family and friends marched out to the assigned pad. With a great deal of excitement and trepidation the igniter was installed and I loaded the rocket onto the launch rod. Joe and Gary kept telling me ‘You're going to love this!!’. “5-4-3-2-1 and the button was pushed. ‘Wow! Color me
gone!’. The rocket canted slightly coming off the pad and rifled
into space. The acceleration was incredible. My son, Eric Jr., was jumping up and down slapping me on the back and congratulating
me. It was a screaming fast flight right up to the waiver. A slightly
large chute and a bit of drift resulted in a 1 mile run across the lake
bed to recover my rocket. The support van showed up to give me a ride
the final 100 feet. The rocket was undamaged! I got a ride back to the
flight line where Greg Lawson
inspected the ‘Miranda’ and signed off my final paperwork. I'm now a Level
II!.... I love this!!!” Welcome to Level 2. On behalf of ROC let me extend my
sincerest condolences to your bank account. In closing, our thanks go, first, to Chris Feenstra, Tom Emerson,
et. al., who manned the RSO table, and second,
to Greg Lawson and Rick O’Neil (the only two members of the ROC BOD who could make this
launch) for their service at the registration desk and as LCO, respectively.
Rick stuck it out as LCO for the whole launch. However, some don’t
think this is an exercise in martyrdom.
The belief is he gets an endorphin rush every time he sends up
12 rockets simultaneously from the front pads (see the
link with his picture on the ROC web site and judge for yourself).
We are also grateful to RocketMotion
and RocketSilo2.0
who were on hand to dole out kits, parts, and yes,
even motors, to an eager public. And finally, we have a special warm spot
for the folks at Alpha
Omega ("We're #1 in the #2 business!") who provided the
porta-potties. See ya next month! |
