  1. Joseph Burns, Tom Fox, Augustine Isitor, Nick Schuyler High Altitude Balloon Instrument Survival Package

  2. Team Members • Joseph Burns, Team Leader • Tom Fox, Parachute Packing • Augustine Isitor, AVMap operation • Nick Schulyer, Flight Predictions All team member’s responsibilities include • Solidworks designing • Earning amateur radio licenses • Package content programming • Package construction • Material testing

  3. Goals • Gather acceleration data to model CFD simulations • Ensure operation and survival of all electronics • Achieve a successful parachute deployment • Use as much automation as possible in fabrication • Test new tracking equipment • Gain practical field experience

  4. Design of Package • Ballutedesign • Torroidal device to maintain stability • Solidworks used for design • Components fabricated in Epilog Laser Cutting Machine • Use of a removable subassembly for ease of installation and maintenance • Keep remanufacturable components in reserve • Must withstand high impulses in ascent and descent, and withstand extreme environments

  5. Skeleton Design • Material chosen was “LitePly” for skeleton • Webbed I-Beam shape chosen as main rib structures • Liteply was coated with CA glue to provide water resistance and act as an adhesive

  6. Table 1. Material Comparison (Matbase) Fabrication of Skeletal Structure • Assembly was completed with “MonoKote” skin for aerodynamics • Elastic cords chosen as shock absorbers • Parachute lines are attached via 2 points of contact to elastic cords and main package ribs • Styrofoam was chosen for lid with wooden washers • Foam nose added to absorb impact

  7. Design and Fabrication of Removable Frustum • Paper-Foam composite board for mounting of electronic components • Nylon hardware chosen • Contains all electronics for versatility and simplicity

  8. Selection of I Beam over Box Beam • Box beam was originally selected • I-Beam was chosen as its replacement • 28 % reduction in weight with maximum 15% reduction in strength • Faster manufacturing and treatment • Box Beam had stress concentrators and was more brittle

  9. Applied Load vsDeflection

  10. Parachute Deployment • Lid is attached to parachute via clip • Lid is detached by NiCr cutters • Ejected lid will drag out parachute then will detach • Lid is disposable and will fall at low speeds

  11. Testing of Package • Package was dropped 13 meters with various configurations • Testing showed that • 4 points of attachment of parachute deployment clip to lid was best • Subsection and contents survived if no parachute deployed • Calculated terminal velocity, depending on Cd, varies from 14.3 to 16.5 m/s for package with no parachute

  12. Testing for Effectiveness in Cold • All primary electronics were subjected to extreme cold (-40° C) • Insulation was applied as needed • Devices were required to continue working after soaking for >3 hours, 4 hour operation was achieved

  13. Method of Operation • Balloon launched with packages • Units tracked via GPS • Signal sent to drop primary package • Control package descends independently after balloon bursts and is tracked separately • Falling package pulls pin to start 10 minute timer on lid and parachute release • Altitude is monitored, signal is sent to package to release lid and parachute at 60,000 feet • Arrested descent until landing • Package retrieval

  14. Electronic Pack Reliability • Redundant tracking components • Automated and manual triggering of parachute deployment • Quad redundant parachute deployment Intuitive Circuts DTMF-8 Yaesu VX-8G/R RCP Electronics RTrak-HAB Logomatic V2 Vectornav VN-100DV

  15. Component Flow Diagram

  16. Tracking of Package • Package has two APRS systems that transmit GPS data on two frequencies • Yaesu GPS has hardware set altitude limit of 18000 m, or 59055 feet, OR speed of 1800 kph, or 1181 mph, before cutout due to regulation • RTrak HAB APRS has 18000 m, or 59055 feet, AND speed of 1800 kph, or 1181 mph limits before cutout • Command package has tracking as well
