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

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

Flight Sequence 1) Liftoff 2) Rocket Coasts after fuel burns out 5 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

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.

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

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

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

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!

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!!
