Project Summary

Project Information
|
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 normal operation of 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.
