RockSat 2008-2009 RamRackConceptual Design Review Colorado State University Zach Glueckert Christopher Reed Timothy Schneider Brendan Sheridan Christina Watanuki Advisor: Dr. AzerYalin October 28, 2008
Overview • Objective: To develop a sounding rocket payload to act as a power bus, data logger, and mounting structure for future scientific payloads • Overview: • Power bus will be programmable to provide varying voltage supplies depending on need • Data logger will provide a broad range of low level sensor communication and will contain several redundant systems • Design will incorporate several permanent sensors that can be used to monitor conditions of this and future flights • Success Criteria: On this initial flight sensor data will provide data on conditions in the immediate region of the payload as well as to determine the ductility of the frame under stresses • Benefits: This information will be used to create constraints on future experimental payloads
Design • Parts • Mounting Frame • Provides structural support for scientific payload and power and control modules. • Sufficient stiffness for a full can future payload. • Battery Packs • Electronics • Redundant 16 channel A/D 16 bit conversion and dual serial input with data logging capabilities. • 4 GB storage available on MiniSD card. • Real-time system monitoring and control.
Batteries • Tenergy Li-Ion • 7.4V • 22000 mAh • 3.2oz • 2.63” x 1.45” x 0.7”
Electronics • ATmega 2561 • Data logging • General I/O • Atmega 168 • System Control • System Monitor • uALFAT-TF • SD card interface • CD74HC4067 • 16-Channel Analog Multiplexer
RockSat 2008-2009 • RockSat Payload Canister User Guide Compliance • Mass: • Estimated use: 2.5lbs • Allotted: 2.5lbs • Volume: • Estimated use: 9” x 2” • Allotted: 9” x 2” • Payload activation • G-switch – no voltage running prior to launch. On launch, G-switch activates latching relay to power electronic systems. • Rocket Interface • Complies with no-volt shorting wire setup.
Logistics • We have contacted the other Colorado schools to plan a meeting. • Looking at the week of November 3rd through the 7th.

Conclusions: • Concerns • Shared canister integration • How to mount three different payloads together • Center of mass/volume with other schools • Mass and volume constraints • Is there any data available on vibrations during two stage rocket launch? • Closing Remarks • Well rounded team • Have the mechanical, electrical and computer backgrounds required to meet project goals • This is a great way to set up CSU for future involvement in RockSAT
