  1. Presented by: Michael Bottiglieri Josafat Gonzalez Madelyn Reid

  2. Overview • Criteria & Constraints • Explore Possibilities • Select an Approach • Bill of Material • Drawings • Build Process • Testing • Problem Statement • Important Dates • Background Information • Customer Information • Deliverables • Brainstorming • Research

  3. Problem Statement Our group is participating in the Team America Rocketry Challenge in which we must design, build, and launch a rocket carrying an egg. The rocket must reach an altitude of 750 feet with a flight time between 40-45 seconds without causing harm to the egg.

  4. Important Dates

  5. Background Forces used in equations Maximum velocity Burn time Descent speed Boost phase Coast phase Wind resistance

  6. Background • Parts of a model rocket

  7. Scope Statement • Purpose • Customers • Mrs. Brandner • Mr. Pritchard • Materials • Criteria and Constraints • Scheduling Conflicts • Track schedule

  8. Deliverables • Rocket • PowerPoint • Technical Report • Testing Results • Engineering Notebook

  9. Brainstorming

  10. Research

  11. Research (continued) • Fin shape • Trapezoidal (most common) • Elliptical • RockSim • Design • Testing

  12. Criteria & Constraints • Target altitude – 750 ft. • Flight time between 40-45 seconds • <1000 grams (2.2 pounds) • One stage engines • Commercially-made engines listed in handbook • ≤62.5 grams of propellant

  13. Criteria & Constraints (continued) • No pyrotechnic charge other than engine instructions permit • Parachute only recovery system for egg and altimeter • Parachute must be 15 (+/-1) inches in diameter • Not commercially-made kits

  14. Explore Possibilities • Possible body tubes • Blue Tube • Quantum Tube • Group member sketches
