Launch Reports


Launch Report for Saturday, 03/01/2003

Saturday, March 1st, our FIRST launch of this year, turned out to be a better launch date than advertised. The weather forecast caused some concern about the wisdom of holding a launch, but with everyone having AP withdrawal, it was decided to give it a go. Arriving at the Amherst field we were pleased to find nearly optimal flying conditions. The sky was overcast, but there were intermittent periods of sunshine. The field was frozen and snow covered throughout the day; the temperature warmed to nearly 40 by the end of the day. Best of all there was no wind in the morning and the winds later in the day stayed below 5 MPH.

Seven flyers and one Team America Rocketry Challenge(TARC) team combined to make 18 flights for the day. Except for three C motor flights, everything was flown on E's or above and the most used motor of the day was a G. Two High power flights were made on H123s.

Mike Glory flew his Estes Mercury Redstone and Fat Boy using C6-3 motors. He also flew his Quest Falcon on a C11. All three made great flights and recoveries.

Mike Jenkins flew his Armageddon Jr twice, first on a G35, then on a G80. Both flights were excellent with reasonably close recovery. This is a really nice rocket he downscaled from plans on the net. He also flew his Estes Blue on an E9 and made a 4th flight on a scratch build using LOC parts.

Ken Karbon made two F powered flights. The first was an Estes Fat Boy that really screamed. His second rocket was from Aerotech, but he didnít provide the kit name on the flight card. Finally he made one of the two high power flights with a LOC Mini Magg on an H123. That was an impressive flight.

I finally got to fly my Baby Bottle Bank. After showing it off at scout building sessions I put it up on a G80 for a straight flight. Then I put together an H123 and let it really rock. Look for pictures on the web soon.

Barry "the DOC of LOC" Lynch flew one of his Scouts on F power twice. This rocket flies well on D's so you can just imagine the altitude it gets on an F. Really fun.

We had our first TARC team make two practice attempts. Their rocket weighed in right at the 3.3 pound limit. Their first attempt was on two G80s. The rocket boosted straight and true off of the pad, but the upper stage failed to ignite. They booster was designed for parachute recovery and the rocket stayed together when the chute deployed, with recovery very close to the pad. Post flight analysis showed the sustainer didnít ignite because they didnít activate the stager. Only one egg was broken, so their padding design worked well. Their second attempt yielded almost exactly the same results. The sustainer didnít ignite, but this time both eggs survived. The stager was active and a field test after the flight confirmed that it was working properly. We determined that the igniter failed because there wasnít enough current to ignite the pyrogen. The next flight will use a lower resistance igniter.
