  2. System Functionality Overview Stowed Deploying Deorbiting

  3. 3.937” 4.488” 0.898” • Maintains 70 in³ volume of original CubeSat structure • Uses only 14 in³ of internal volume 3.937”

  4. G-10 Wire Cap 0.028 lb G-10 Cap 0.0356 lb G-10 Wire Mount 0.00387 lb Mylar Film ˂0.0001 lb Aluminum Footplate 0.00336 lb Aluminized Mylar Inflatable 0.13684 lb Aluminum Baseplate 0.40496 lb TOTAL Estimated System Mass 0.61273 lb 20% of Max CubeSat Mass

  5. Wireless Electronics • Software • Circuit Board Fabrication • Approx. (1 in x 0.75 in) • Vacuum Testing

  6. Cutting Wire Deployment Validation • G-10 Glass Epoxy Sheet • Thermally & Electrically Non-Conductive • 3-D Printed Baseplate • Successful insulation of cutting wire

  7. Film Materials and design • Non-pressurized baseplate • Mylar Strap design • Testing results

  8. Inflatable Development • Inflatable Cross-Sectional Area: • 0.24 m2 (366.43 in2) • Desired/Theoretical Area: • 0.37 m2 (562.77 in2) • Orbital Decay Period • Folding Pattern Constraints

  9. Thermal Analysis Thermal Analysis Template • Results and Conclusions

  10. Heating Element • Use Kanthal wire as a heating element to build up heat and start the sublimation process. • Test insulation and other methods to build up heat in the CubeSat.

  11. Benzoic Acid Application Results • 3 Methods • Powder – from literature • Paste – best • Aerosol – weak • See if it attached to the Mylar • Paste and Aersol

  12. Baseplates

  13. Tether • Four point system • Kevlar • Science potential • Addition of strain gauge • Cutting system

  14. Budget • G-10 Material - $85.95 • 24 Gauge Cutting Wire - $4.00 • 34 Gauge Cutting Wire - $9.00 • Graphite Thermal Gasket - $23.07 • Sprayer Val-Pack Kit (2x) - $56.71 • Kevlar Braided Cord - $16.98 • Hardware - $18.40 TOTAL: $214.11

  15. Conclusion • Low mass, volume, and cost design • Working prototype • Space Act Agreement (SAA) underway with NASA Langley for testing and validations
