Thermal Vacuum Chamber Modification, Testing, And Analysis, Jared C. Lehmann
Thermal Vacuum Chamber Modification, Testing, And Analysis, Jared C. Lehmann
Master's Theses
This work discusses the modification and analysis of the Blue Thermal Vacuum Chamber (TVAC) located at the Space Environments Lab at California Polytechnic State University, San Luis Obispo. The modified design has a cylindrical test section and can accommodate 6U Cubesats or larger for educational or research purposes. The sizing process for the modified shroud cooling system and modular heating plates is discussed. The modified cooling system uses existing nitrogen plumbing into the chamber and control systems with a new copper shroud. The modified heating system uses modular heater plates, which utilize the existing three heater strips. The modified system …

Mission Statement
The purpose of this project is to design, build, and test a thrust-vectoring rocket nozzle which will aid in controlling the trajectory of a solid-booster rocket. The system prototype must meet the requirements set forth by the sponsoring enterprise.
The Enterprise
Stellar Exploration is a small space systems technology company located in San Luis Obispo, CA. Stellar Exploration is currently seeking a thrust-vectoring system for its Silver Sword rocket.
Project Scope
The design and analysis portion of this project accounted for a system that would be mounted on to a rocket for operational flight. Therefore, this team has …

The Next Generation Router System Cooling Design, Garrett A. Glover
Master's Theses
Advancements in the networking and routing industry have created higher power electronic systems which dissipate large amounts of heat while cooling technology for these electronic systems has remained relatively unchanged. This report illustrates the development and testing of a hybrid liquid-air cooling system prototype implemented on Cisco’s 7609s router. Water was the working fluid through cold plates removing heat from line card components. The water was cooled by a compact liquid-air heat exchanger and circulated by two pumps. The testing results show that junction temperatures were maintained well below the 105°C limit for ambient conditions around 30°C at sea level. …
