1. Team 7139 Madison West High School, WI
Our Experience at TARC
Duncan A, Alyssa C, Misha K, Yifan L, Enrique O, Paul S, Tianchi Z 1

2. The Design & Construction Process
Design 1-Enrique and Allissa's Rocket
Designers:Enrique Olivas and Alissa Chen
Design 2 -Ultralight
Design 2 was chosen because it was the most resistant to weathercocking, it used the least amount of fuel to reach target altitude, and it was easiest to build
After flight testing, modifications were made to the design to increase reliability which will be talked about later
Designer: Duncan Adams
Design 3-Chinese Dragon
Designer: Yifan Li
The rockets were designed with the software Rocksim 2

4. Flight Sequence 1) Liftoff 2) Rocket Coasts after fuel burns out5
3&4
1) Liftoff
2) Rocket Coasts after fuel burns out
3) Flight computer fires primary charge near 750 ft
4) Parachute deploys 2
5) Rocket reaches apogee, altimeter fires the backup charge
6) Rocket descends under the parachute 6
7) Rocket lands 1 7

5. Flight Testing Process
We started with many designs, then flew them to free apogee
We added smart deployment (flight computer)
We found that the rockets were moving too fast at ejection charge firing, so we added weights to slow them down.
We also reefed down our parachute to achieve target duration.

6. Changes after Flight Tests
Reefing (tying) the parachute
Flight computer for smart deployment
Weights to slow rockets down

7. Eggs cracking due to insufficient space
Problems We Faced
Problem
Solution
Eggs cracking due to insufficient space
Longer egg-bay by 1 inch

8. Teamwork
All team members created a rocket design or collaborated to create one
Everyone was there for the construction
All the team members attended several flight sessions
Through Rocket Club and TARC we learned that teamwork is vital, and we wouldn’t have succeeded without teamwork

9. Lessons Learned We learned many facts about rockets
We learned that teamwork is a necessity to success
We learned important lessons about troubleshooting, persistence, and problem solving
The most important thing is to have fun!

10. Conclusion See you next year!!
This year was very enjoyable for all of us. We all achieved a lot, including more knowledge, and new friends. Our interests and aspirations in the sciences have been applied and affirmed through this challenging and rewarding contest. We will certainly have even more fun in rocket club in the future!
See you next year!!
