Study of the Thermal Physical Properties of Insulating Materials in A Titan Environment

Dragonfly is a planned rotorcraft mission that NASA/APL will be sending to Saturn’s moon Titan to study its chemistry. The Dragonfly Mass Spectrometer (DraMS) is a mass spectrometer that is being developed to identify different kinds of organic material that comprises Titan’s surface. The Cryogenic engineering team on DraMS is developing and interface between the room temperature rotorcraft body and the near-cryogenic temperatures of an onboard sample chamber, while minimizing the thermal leak to the Titan environment. As part of design process, the Cryogenic team has built a conductivity test rig for testing the thermophysical properties of candidate insulators, which includes Rohacell 31HF and hollowed 3D printed PEEK structures, at simulated Titan environmental conditions.
