• 6 diameter
• Estimated cost 7,000
• Florida Space Authoritys SuperLoki
• 38,000N-s, 2.1 second burn, gt135-G
• 4 diameter
• Little to no cost, with FSA partnership

11
Wind Tunnel Testing

• Objectives
• Vary fin angle and determine correlation between
  angle and rate of spin
• Build ½ scale model (customized O)
• SuperLoki would not apply spun by rail, not
  fins
• Difficulties led to measurement modifications
• Angles too difficult
• to mark and measure,
• especially in test section
• Measured free-stream
• velocity vs. spin rate

12
Wind Tunnel Testing

• Materials donated
• Home Depot
• Space Coast Hobbies
• Measurements taken with light strobe tachometer
• Steel rod runs thru body tube and wheels

Experiment Conclusions

• The higher the velocity, the greater the spin
  rate
• The maximum spin rate (constrained by the wind
  tunnel speed range) is about 3 rps
• Without dart fins the model was much more
  unstable
• Testing helpful, but higher velocity needed
• Our rocket will only be at these speeds for
• a fraction of a second

18
FSAs Offered Support

• Agreed assistance
• Use of launch pad 47
• Two SuperLoki boosters
• Surplus avionics
• Payload integration time
• Tour of pad and facilities
• Agreement by
• S. Richard Scredon
• Director of Special Projects
• October 17, 2002

19
SuperLoki Decision

• Projected financial status too uncertain
• Tradeoff High potential damage to payload, but
  sufficient motor secured
• Project needed definitive direction
• Partnership with FSA paves way for future
  collaboration

20
SuperLoki Technical Approach

• Five major factors for immediate attention
• Launch Rail
• G-loading
• Interstage adapter
• 45th Space Wing
• Material Selection

21
Launch Rail
22
Launch Rail
Exit
Aft
(Constant diameter)
23
Dart Fin Constraints

• Must fit step diameter in rails

24
Handling 100 Gs

• Original idea solidify electronics to board
  with epoxy/polyurethane coating
• Loading on electronics chassis
• Spring support (stores energy)
• Crushable support (absorbs energy)
• Structural support (dart tube stress analysis)

25
Interstage Adapter

• Dart tail rests inside interstage
• Need to fit up to 3 dart into 1.5 opening

• Requires test launch to prove our adapter
  works safely

26
45th Space Wing

• May require a new Program Introduction for entire
  vehicle
• Require proof of safe operation of interstage
• Require finite element analysis
• to prove the boosters structural
• integrity will not be compromised
• by the larger dart size.

27
Material Selection

• Fab-Tech Industries
• - Aluminum, Steel, Stainless Steel
• Dart Body Material
• Stainless Steel
• Strong
• Corrosion Resistant
• Withstands harsh atmospheric conditions

28
Material Selection

• Starute Parachutes
• -Aluminized Mylar
• Ablative Coating
• -Thermalog T-230
