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 rockets 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 tocomputer simulation data and
  onboardtelemetry to determine the accuracy
  ofour measurements.

Test Plans and Procedures

• Follows NAR regulations
• Check for personnel and environmental hazards

10
Scale Model Flight Test

• January 10th, 2009, 400PM
• Behind Denmark Elementary School on public land
• Christened Dark Density
• Purpose to test integration of pods, proof of
  concept, and parabolic microphone

11
Scale Model Flight Test

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

12
Challenges

• Synchronization of beepers
• Volume of Beepers
• Tracking of rocket with parabolic microphone
• Triggering Payload Events
• Parachutes ability to handle weight of rocket

13
Ejection Charge Amount Test
Dual Deployment Avionics Test

• Testing to take place after construction of Dark
  Doppler

• Black Powder Weight (grams) (0.002 F L)
  1.0
• Pyrodex Grade P Weight (grams) (0.002 F L)
  2.0
• F Ejection force on Nosecone in poundsL
  Length in inches of body tube to be pressurized

14
Payload Integration Feasibility

• Main Payload Bay
• The temperature logger, barometric altimeter,
  beeper battery and battery holder will be
  securely mounted and enclosed within the payload
  bay
• Located directly below the nosecone of the
  rocket.
• Porting will be constructed for the flow of
  ambient air into the payload bay.

15
Beeper Pods

• Two high-volume piezoelectric beepers will be
  mounted on the outside of the airframe directly
  below the nosecone with the sound ports facing
  down.
• Surrounding the beepers will be a
  custom-fabricated shroud to reduce drag and
  protect the beepers.

16
Safety
We will continue to

• 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
• Safety glasses
• Masks
• Ventilation systems

17
Budget

• Expenses
• Donations
• Fundraising
• NASA payment
• 600
• 800
• 950
• 1500

We are feeling pretty good at this point of the
project, but with the economy outlook, it is
becoming difficult to determine how many more
donations we will receive. A booyah fundraiser
is planned for March.
18
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 were showcased in various local newspapers.
