Mark B. Bundick - 26 May 2004 01:44 GMT
First, hats off and three cheers to Trip Barber and his merry band of
70 NAR members who wonderfully executed the 2004 TARC Finals.  These
committed NAR volunteers came from all over the country to spend their
weekend on a rocket range but did no flying. I again this year heard
the VIP's speak glowingly of the quality and smoothness of the range
operation.  Having run two NARAM's myself, I know what it takes to
pull a team together to do this stuff, and I stand in awe of the
organizational display Trip and his team put on at Great Meadow.

Barb and I flew out on Thursday afternoon, and then had dinner in Old
Town Manassas.  NAR members attending NARAM and looking for places
above chain or fast food should check this part of town out.

Friday, Barb and Jo Ann Rachor toured three different Smithsonian
museums while NAR Secretary George Rachor and I had two separate
business meetings.  When we were done with our work, we met Barb and
Jo Ann at the National Building Museum. The structure is itself is a
marvel -- 15 stories high, made from 15 million + bricks, and open all
the way to the roof. There are giant Greek columns holding up the
roof, and smaller ones along each other gallery. The exhibits were a
bit dull and Spartan, so we cut back to the Metro and back out to the
Vienna Metro stop (10-12 miles from our Manassas hotel.) and got a
quick rest before the contestant's briefing at Osborne Park High
School.

Trip briefed the range crew first, going over critical elements of the
operation, and making sure everyone had their standard issue NAR
"uniforms"; NAR shirt and hat with khaki pants or shorts.

102 teams with about 600-700 kids and supporters showed up, and could
hardly contain themselves.  When Trip asked "Anybody here ready to fly
some rockets?" they about took the roof off the place.  John Douglas,
the AIA Executive Director, then proceeded to ratchet up the crowd
more by asking "Who's going to win tomorrow?"  It took him the better
part of a couple of minutes to get the crowd quiet enough to finish
his remarks.  Vern Estes also addressed the contestants, and I suspect
was warmed by both the reception and the bright future seated before
him. The Rachors, Bundicks and Estes' then went off for a nice dinner.

Saturday dawned bright, with high ceilings and dead flat calm winds.
Barb and I got to the field before 8 AM. While she ran off to get
pictures, I hung around the VIP area, chatted with JP Stevens of the
AIA and the rest of the AIA staff.  I watched JP coordinate the F-18
flyover with a forward air controller radio.  Demonstrating why this
man's such a class act, he invited the pilot's sister who had shown up
to see him perform the flyover, to join us in the VIP area, and also
let her chat with her brother via radio.

After an appropriate introduction, a volunteer choir of TARC
contestants joined the color guard, sang the National Anthem, and then
the F18's flew over.  As they got immediately over the launch site,
they went off in 15 deg. separate paths, with both of them in full
afterburner.  The thunder over the launch site was stunningly loud,
sweet music.  After they blew out of town, a salvo of 8 HPR models
lifted off in rapid succession.  Barb got a great photo of the
residual smoke trails, which persisted nicely in the non-existent
winds.  PA announcer Alan Williams roared "Ladies and gentlemen, start
your rocket engines!", and the contest was on!

The first bird off the pad worked fine, as did roughly 70% of the
entries in total, a much better track record than last year.  Lowering
the altitude helped, as did a year's experience on which to draw.  85
teams who made the finals last year tried to qualify again this year,
but only 38 of them succeeded.  Average 2003 qualifying score was 99
vs. 2004's 38.  The flyers on the field were the cream of the crop,
for sure.

I'm hoping Ted Cochran does his wonderful analysis of the flight
permutations again (hint, hint). But it looked to me as if most kids
gave up on composites and complexity. They went simpler and
(hopefully) more reliable.  I did notice a lot more deliberately spun
models this TARC than last. Nearly every one of those went up darned
straight.  There also appeared to me to be more consistency from rail
launched birds, even though the winds never picked up.

NASA Marshall (which deals with a lot of NASA's educational outreach
stuff) sent up a huge trailer with an exhibit. They also had a giant 3
story inflated space shuttle. Other groups on displays included
Louisiana University (which gave out Mardi Gras beads), NASA's Wallops
Flight Center, several other educational groups, and a simulator for
flying the 1911 Wright Model B Flyer. Even the Central Intelligence
Agency was there, handing out pins and pencils to the crowd.

CNN again provided live coverage.  VIP's included Sen. Mike Enzi
(whose 8 month old grandson was a hit, along with J. P. Steven's 11
month old son), Homer Hickam, Jim Pruitt (NASA Marshall's education
director), Dr. Adena Lotson, NASA's Associate Administrator for
Education, Craig Stetle, head of the Moon-Mars project, a huge
contingent of aerospace executives, and astronauts Jay Apt and Charlie
Walker.  

It was also fun to bump into VIP's unexpectedly.  One I was personally
happy to see was Ken Hyde, the head of the Wright Experience.  I
chatted with him about my Kitty Hawk visit on December 17, 2003, and
his plans for the third Wright Flyer his team is building.  I also
finally got to meet the Wallops Public Affairs Officer, Keith Kohler.

The HPR demo was a great success.  Sen. Enzi spent time chatting with
the flyers and clearly enjoyed his time out there.  He was invited to
launch several of the birds, including Bill Schorwer's TV rocket.  A
bit of disappointment was the failure to ignite the K550 Nike-Smoke
scale bird.  After failing on the third attempt due to schedule
constraints, Sen. Enzi remarked "Well, I guess that's the last time
they'll let me try to launch it."  

Another Kodak moment occurred for Doug Pratt, who flew a hybrid bird.
After Doug's successful flight, Sen. Enzi wandered over to George
Rachor and I and said, "I've never seen one of those before.  That was
kind of neat!"  I don't think Doug's stopped beaming ever since I
related that story to him at the range crew reception that night.

You should visit the rocketcontest.org site for complete results.  On
top of the regular contest, a number of special awards were given this
year to keep things interesting.  

The Northrop Grumman Corporation Award went to the "Team With the Best
Team Uniform".  Lots of teams has special shirts, and we had one that
would have made Harry proud as they wore flight suits. Some went even
farther. One team with a mythology theme for their group wore togas.
But Hickory High School took the top slot with their red and white
"Cat in the Hat" stovepipe hats and red bowties.

The Parker Aerospace Award for "Best Rocket Recovery Effort" brought
back competition flight memories.  The team from Shelburne Community
School won for recovering theirs from a 60 foot tree.  They arrived at
the awards stage complete with rocket entangled in a branch.  Nice
showmanship, guys.

The Aerojet Award for the "Lightest Rocket That Worked" contrasted
Heuvelton Central School at 293 grams against the Alliant Techsystems
Award for "Heaviest Rocket That Worked" going to East Central High
School at 1,400 grams.  You do the math.

Finally, I think all NAR rocketeers would have appreciated winning
either the BAE SYSTEMS North America Inc. Award for "Most Complex
Rocket That Worked", or Honeywell's Award for the "Team With the Most
Sophisticated Control Strategy".  Way to go, Shelby Junior High, and
Claymore High School; we're all jealous.

NAR members looking to get in on TARC 2005 should check out the
rocketcontest.org website, and ping Trip Barber to see if you can
claim a slot on the range crew.  You'll get a uniform shirt not
available for sale, and the rocketry experience of a lifetime.  

As hard as it might be to believe, TARC 2004 was better than TARC
2003.  I had more fun, met a lot more people, and saw great rockets,
big and small, all day long.  The hobby's future is brighter with us
supporting these kids, and so is aerospace's.  If one day, I can look
at some astronaut getting ready to go to the moon or Mars and hearing
them say "Team America started me down this path", I'll certainly be a
proud and happy NAR president.

Personal aside: I had way too much fun at this event.  I go there, I
do nothing but schmoze, and everyone who meets me is interested in the
hobby, the kids, our mission and our organization.  By far and away,
it's turned into the absolutely the best perk of being NAR president
(grin).

Kudos sir. TARC is far and away an unqualified success for NAR and model
rocketry generally.

I'm sure the weather, the motor rule change, and the fact that 38/102
teams were veterans vs. the all rookie field in 2003 were all
contributing factors.

38 sounds good, but only 12 of those 102 qualifying teams managed to
score below 40 in the finals.  I'd guess the ability to take a
Mulligan in qualifying really skews the comparative results. OTOH,
half the finalists scored within 145, and 46 within 10% of the desired
altitude.  It looks like maybe 40% had problems, e.g. low performance
from non vertical flight, or cluster ignition failure, or broken egg,
unstable, etc.

The spinning rocket issue is one that interests me. Were more models
spun this year simply because more clusters were flown?  Were more
models spun because the veteran teams remembered flying in bad weather
in TARC 2003?  Where did they get the idea to spin models?  Was it
from individual research and experience, or on-line open discussion
lists, or taught from the mentors and coaches?  They certainly did not
learn it from running Rocsim.  More generally, I'd like to read
articles written by student participants about the technical,
operational, and tactical lessons learned.

There was also a quiet discursion of flights on RMR about non vertical
flights due to a cluster motor failing to ignite.  I thought about
doing an R&D project to determine optimal fins size and fin cant angle
for a TARC like model with one cluster motor ignition failure.
However, this is project best left to the TARCians and NARAM B
division competitors.

The team winning the Honeywell control award was DQ'd.  Ouch!  I
wonder what they did to earn the award?

While I was looking that up, I noticed that Clayton High from MO had
three teams, all with closely grouped low scores.  I'm wondering if
they functioned independently, or more like a motor sports team
fielding three cars in the same race, sharing knowledge. Did they all
use the same batch of under performing motors?  Did the third team to
fly not think that maybe they should remove some ballast or something?
I'm sure that there are at least 100 good stories and lessons learned
coming out of TARC 2004.  I hope we get to read about some of them?

The award write-up allows DQs to win (best laid plans....)

They eliminated a lot of variability by using a nice tower
launcher, and had a fairly sophisticated weight adjustment system
based on a simulator-derived table that took into account
temperature, humidity, etc.

I think the DQ was because they didn't get a motor lit...

Like yeah...  Wasn't the team a group of freshman?  :-)

I see what you're probing at (if I got it right) with TARC is more
in-line with the NCAA basketball tourney where every year is fairly
wide open.

I've got this database of some NAR/FAI contest flights and did some
comparisons...  

1/2ASRA    27%   DQ Rate
BELA                28%
CELD                28%
BHD                28%
BSD                28%
1/4ASRD    28%
1/4ASD     32%
FSD                33%
1/4ARG    33%
1/2AFW    33%
DBG                 33%

The DQ percent of this years TARC was what, about 29%?  Looking at the
Cumulative Distribution of scores, the shape of the curve looks very
similar to FAI B-PD and maybe FAI A-PD where they were going for
Maxes.  Good stuff...

Andy

I don't follow NCAA basketball, but are you suggesting that high
performing teams make it to the NCAA tourney, but few of them display
that same high perfomance in the pressure if a NCAA tourney, and that
TARCians just crack under the pressure of the finals competition?  I'm
not probing at anything.  I'm just musing the posted results and
Mark's commemts.  I'm sure people who were actualy there can provide a
better assement.  Bunny suggested that the competitors were MUCH
better this year because the average qualifying score went from 99 to
38 in an easier contest.  I'm suggesting that the real improvement in
contestant skill may not be as great as Mark and his chosen metric
suggests.

March Madness is an interesting time of the year.  It's a single
elimination tournament and in the end, everybody but one school will
suffer a loss.

It would be too obvious to say that some teams handle the distractions
of being on the road better than others. For all I know, some may
prefer the distractions (?!?)  

Based on simply two years of watching , I'm happy to claim that the DQ
rate from our area teams is about half of the national average yet
puzzled that for two years in a row, have consistently flown to lower
altitudes than expected.  This year, their models were flying straight
as a laser so I'm wondering if it's either the local weather or motor
variability.  Oh well...  I understand everybody had a good time.

>not probing at anything.  I'm just musing the posted results and

Ahhh...  Cut him some slack.  After all, he's hobnobbin with the big
boys now and may have lost touch for the moment...  :-)

When I inspected the cumulative performance distribution (CPD) curves
from the two years, I see two distributions within each year.  Those
in the pack and the other pack of those who were probably like me in
college.  Last  year, the curves indicate 30% of the teams were in the
hunt and this year 56%.  For discussion, NAR contests typically has
only a fraction of contestants in the head pack. As I mentioned in the
prior post, the shape of the TARC CPD's resememble that of the FAI
B-PD events.  Whatever, I guess the gist is if the event coordinators
wants a tightly contested event or one where the pack gets spread out.

I don't think Mark has lost touch.  He is doing a great job, along
with Trip, the volunteers and contestants.  I'd rather keep him
engaged than let him slack off...

I agree that that is a better metric. However, EVERY team in the
finals is qualified and should be in competitive pack.  The altitude
is lower, and the weather was much nicer, which certainly helped, but
I don't know how much.  The fact that 38 teams returned from the first
year also allows for more statistical analysis.  Did the verteran
teams do significantly better in thier second year, or did they
randomly rise and fall in relative demonstrated skill?  The allowable
motors also chnged, in a way that should be expected to show better
results.  

>For discussion, NAR contests typically has

Agreed.  While interesting, I don't see the relevance to comparison
with FAI B-PD, or even NAR contests.

> I guess the gist is if the event coordinators

I'd guess they like to see every team make a qualified flight within
15% or so of the desired altitude.  But the fact is randomness
dominates the determination of the top money winners.  Requiring teams
to say make three flights and average the altitudes would help reduce
the randomness, helping the highest skilled teams to actualy finish in
the prize money.  Likewise, making the event more difficult, would
help insure that the highest skilled teams actualy finish higher in
the rankings than lower skilled teams.  Of course the other idea is to
not pay out the prise money based solely on rank, but on actual
performance.  Say, $100 - $1/foot of error. Of course you would still
have to make it worthwile to participate.  And yes, like T ball, they
are all winners.

Exactly.  We should talk this up more, but I'd like to hold off until
more reports are written and published.
