CubeSat De-Orbit Device Team Status Report 2 Team Members: Edwin Billips, Cian Branco, An Kim, Langston Lewis, Mackenzie Webb, Alexander Streit, David Warner, Benjiman Cawrse Overview • Team is transitioning towards experimental testing and lab work • There has been steady progress albeit slower then first expected • We expect to perform experimental tests for the O-Pod deployment device and aerodynamic brake • We also expect to have purchased a large majority of the electronics determined necessary for the mission of our flight test article in interface with RockSat-X. Testing Platform • Team is still pursuing a sounding rocket test flight at Wallops Flight Facility through the RockSat-X program which is still considered the best option for the successful completion of this project • 124,000 ft. High Altitude Balloon testing platform ruled out because it does not provide enough of the necessary conditions of space to adequately validate the performance of our aerodynamic brake. Airbag Calculations Altitude (km) 70 80 90 100 110 120 Ambient Pressure(mmHg) 0.039 7.894E-03 1.360E-03 2.415E-04 5.393E-05 1.913E-05 Saturation Temp. (*C) 43.20 25.40 8.35 -6.33 -17.67 -24.86 • It is determined at 90 km to be the ideal altitude to release the membrane and inlfate the CubeSat. Airbag Testing Supplies Progress Update • • • • Specification of Necessary Components complete First proposal for components turned in Possible grant from Dr. Popescu Construction of and power and telemetry systems to begin shortly Experiment Timing Start pictures Power up Signal Power up & release CubeSat Start Taking Pictures Release Brake Turn off Experiment Release brake Power off Time(seconds) 0 1.5 5 330 Arduino Board Schematic 1st Electrical Budget Electrical Team budget Component Cost Xbee Wifi (2x)($35.00 ea) $70.00 Linksprite JPEG camera $49.95 UltraLife 9V lithium battery (2x)($5.15 ea) $10.30 100 Resistor Assortment $6.19 Insulated 9V Battery Snap connectors($2.19 ea) $4.38 Wiring $8.99 Total: 149.81 O-POD Deployment System Cian Branco, David Warner O-POD 4.0 O-POD 4.1 Quick Release Mechanism ● Solenoid Option ● ● ● 2 linear solenoids hold spring plate, retract by signal “cheap & simple”, not ruled out yet. Vectran Line Option ● ● ● Quote on Vectran: ~$1 to $3 per foot (in budget) High strength, cuts with heat → very useful material Have existing schematic from Cal Poly & QRM Electrical Schematic ● Cal. Poly & Stanford design Questions ?
