2. Design and Construction Process We used RockSim to aid in the design process We used RockSim to aid in the design process BT80 body tube BT80 body tube We designed our own fins We designed our own fins We used tools such as drills, glue, and a Dremel to build the rocket We used tools such as drills, glue, and a Dremel to build the rocket We used a PNC-80k nose cone We used a PNC-80k nose cone We used a F24-4W motor We used a F24-4W motor We used a 70” x 7” streamer on the cargo unit and nose cone We used a 70” x 7” streamer on the cargo unit and nose cone During the design process, we considered cost and availability of materials During the design process, we considered cost and availability of materials 2

3. Teamwork We all contributed to the design, development and test launching of the rocket We all contributed to the design, development and test launching of the rocket Jon constructed the body tube Jon constructed the body tube The construction of the egg compartment was mainly done by Disa, Ben, and Mattie The construction of the egg compartment was mainly done by Disa, Ben, and Mattie The streamers were shaped and ironed by Samantha and Becca The streamers were shaped and ironed by Samantha and Becca Disa and Kathleen worked on the fins Disa and Kathleen worked on the fins 3

5. Lessons Learned A weight concentration towards the center of the rocket will cause it to descend with a horizontal tilt, increasing flight time A weight concentration towards the center of the rocket will cause it to descend with a horizontal tilt, increasing flight time Design and development time Design and development time Altitude inconsistency may be controlled by adjusting rocket’s mass Altitude inconsistency may be controlled by adjusting rocket’s mass 5
