P20129: Flight-Ready Heat Switch

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.
