Wireless Electronics • Software • Circuit Board Fabrication • Approx. (1 in x 0.75 in) • Vacuum Testing
Cutting Wire Deployment Validation • G-10 Glass Epoxy Sheet • Thermally & Electrically Non-Conductive • 3-D Printed Baseplate • Successful insulation of cutting wire
Film Materials and design • Non-pressurized baseplate • Mylar Strap design • Testing results
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
Thermal Analysis Thermal Analysis Template • Results and Conclusions
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.
Benzoic Acid Application Results • 3 Methods • Powder – from literature • Paste – best • Aerosol – weak • See if it attached to the Mylar • Paste and Aersol
Tether • Four point system • Kevlar • Science potential • Addition of strain gauge • Cutting system
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
Conclusion • Low mass, volume, and cost design • Working prototype • Space Act Agreement (SAA) underway with NASA Langley for testing and validations
