  1. Temple University Advisors: Dr. John Helferty & Dr. ShriramPillapakkam Charles Wright Jinyan Chen Billy Cheng Brittany Gray Rock it rocke

  2. Objectives • Design, Build, And Test A Vibration Suppression System To Counteract Launch Vehicle Vibrations • Measure The Vibration Environment Inside The Terrier-Orion Rocket • Will Use Two Identical Vibration Measurement Systems • A Custom Built Passive Damping System • Rigidly Attached System • Compare The Designed Passive System Vs. The Rigidly Mounted Undamped System

  3. Review Of Last Year’s Launch Data

  4. Review Of Last Year’s Launch Data 1st phase boost 2nd phase boost Chute deploy Z High range acceleration Anomoly? Design problem is to reduce these spikes on both graphs

  5. Review Of Last Year’s Launch Data

  6. Benefits • Efficient Vibration Isolation Systems For Small Payloads • Increased Operational Performance Of Onboard Sensing Equipment • Better Protection Of The Sensing Equipment

  7. Concept Of Operations RBF Wires Connected System Deactivated Flash Memory Activated Rocket Launch Level Translator Activated Payload Retrieval Microcontroller Activated G-Switch Activated Z Accelerometers Activated Rocket Splash

  8. Structural Drawing

  9. Final Payload

  10. System Schematics • Main Board • Consists Power Supply System • Basic Stamp Microcontroller • External ADC, Memory

  11. System Schematics • Z-Axis Acclerometers • Consists Of Hi-G And Precision Accelerometer

  12. Structure • Two Plates Containing Identical Electronic Equipment On Each • Comparison Of The Designed Vibration System With That Of A Rigidly Mounted Identical Measurement System

  13. Subsystem Requirements • Power (For Each Identical System) • Two 9V Lithium Ion Batteries Connected In Parallel • Provides Continuous Power Throughout Entire Flight • Voltage Regulators Will Step Voltage Down To 5 And 3.3V

  14. Data Storage Overview Microprocessor Analog Data (Sensors) ADC Memory Dump (PC) Write Memory Flush Data Flash 16Mbits = 2MB Memory Buffer

  15. T H A N K Y O U ! And After a Year of Dealing With Shawn Carroll This is How We Feel!
