Team Vision for Problem Definition Phase

For Phase I, our team accomplished these tasks:

Project Summary

The mechanical heat switch is a device that is used as a secondary stage of cooling an adiabatic demagnetization refrigerators (ADRs). The heat switch allows cooling of high sensitivity imaging sensors to allow for deep IR detection. A lab prototype was previously designed; however, the design lacked durability and used ferrous materials which interfere with the ADR.

The goal of this project is to iterate the design of the lab prototype to utilize non-ferrous materials and ensure that it maintains reliability at 2 Kelvin for at least 1000 cycles per customer requirements. The system must be designed to fail open in flight and must operate in a sounding rocket for at least ten minutes at altitudes in excess of 350 kilometers. The heat switch must be proven to meet these requirements via tests conducted in the laboratory.
