2. Our Mission Statement  Launch a high-power rocket to an altitude of one mile carrying the Operation: Epic Beep payload package. At lift off, the rocket’s payload will begin emitting a series of high volume “beeps” at one- third-second intervals. These beeps will cease at apogee. By recording and analyzing the beeps, we will be able to determine velocity, acceleration, and altitude of the rocket throughout the duration of its flight. This data will be compared to computer simulation data and onboard telemetry to determine the accuracy of our measurements.

9. Test Plans and Procedures  Follows NAR regulations  Check for personnel and environmental hazards

10.  January 10 th, 2009, 4:00PM  Behind Denmark Elementary School on public land  Christened “Dark Density”  Purpose to test integration of pods, proof of concept, and parabolic microphone Scale Model Flight Test

11.  58% Scale of Dark Doppler  Projected altitude: 2000 Ft.  Weight: 22 oz.  Height: 42”  Results: Stable Flight Stable Flight Small degree of weather cocking Small degree of weather cocking Soft landing Soft landing

12. Challenges Addressed  Synchronization of beepers  Volume of Beepers  Tracking of rocket with parabolic microphone  Triggering Payload Events  Parachute’s ability to handle weight of rocket

13. Dual Deployment Avionics Test Black Powder Ejection Charges  After extensive testing we determined that more powder was needed. Slowly adding more powder in testing we worked up to the final amounts needed. Powder Amounts  Drogue = 1.0g  Main =.5g  Motor Ejection (Drogue) = 1.0g 4F Black Powder (grams) = Compartment Diameter2 (inches) x Compartment Length (inches) x.006  Drogue Powder = 2.175” x 2.175” x 26” x.006 =.74 grams  Main Powder = 2.175” x 2.175” x 10.75” x.006 =.31 grams

14. Payload Integration Feasibility  Main Payload Bay The temperature logger will be securely mounted and enclosed within the payload bay, located directly below the nosecone of the rocket. The temperature logger will be securely mounted and enclosed within the payload bay, located directly below the nosecone of the rocket. Located in the nosecone, our battery pack Located in the nosecone, our battery pack Porting will be constructed for the flow of ambient air into the payload bay. Porting will be constructed for the flow of ambient air into the payload bay. Altitude tracking will be accomplished via the deployment altimeter in the avionics bay. Altitude tracking will be accomplished via the deployment altimeter in the avionics bay.

15. Beeper Pods  Two high-volume piezoelectric beepers are mounted on the outside of the airframe directly below the nosecone with the sound ports facing down.  Surrounding the beepers are specially designed, sound-increasing megaphones which will protect the beepers in flight.

21. Safety  Adhere to MSDS standards  Follow shop safety  Respect dangerous chemicals and abide by instructions  Follow instructions on rocket assembly  Use proper safety equipment such as: Gloves Gloves Safety glasses Safety glasses Masks Masks Ventilation systems Ventilation systems

22. Budget  Rocket Expenses  Public Relations  Donations  Fundraising  NASA payment $1400$600$2305$2200Pending.... We are confident at this point of the project, but with the economy outlook, we are not anticipating many more donations. The planned booyah fundraiser was an EPIC success.

23.  Besides using booyah as a fundraiser, we displayed our rocket and answered questions to educate the public about our journey of epic rocketry. BOOYAH FUNDRAISER

24. Outreach  We presented rocketry basics to over 150 students from grades 3-7.  We continue to distribute our brochures explaining SLI and our project.  We continue to be showcased in various local newspapers.
