Members from
all four teams traveled to the
Virginia launch site on Saturday, March 26 to try to qualify
for the TARC finals. The weather was cool (50f) and the wind was
variable (5mph to 10mph). We had little risk in
recovery. We decided to stay late and complete our TARC
qualification flights because the weather was reasonable.
Bob launched his Pringles
rocket to use up an old motor.
Objectives:
- Conduct one test and one qualification
flight for each team.
Lessons and Actions:
- We conducted 13
flights - the most we have ever done in one day. The range safety
officer got tired saying Explorer Post 1010.
- Almost all our
flights were close to the target altitude of 750ft, The
E30-7T performed very well.
- We had problems with
the deployment of the parachutes. The shock cord came apart
(9212#1). The chute floated too much (9213#2, 9214#3). Or the chute
did not fully deploy (9212#3, 9213#3, 9215#4).
- Only one egg was broken.
- We only had a few igniter problems. Two times we
failed to reconnect the launch wires following another team's use of
the adjacent launch rod.
- The rocket weights were not reliably recorded.
