ReasonFor Thermal System Detail GroupFuture payload testing
Project Goal
Create a thermal shroud to simulate space environment Create a thermal plate prototype to test the conceptCreate a thermal shroud from the prototype
Heat Transfer
(sciencelearn, 2009)
Heat Transfer
BackgroundThermal Shrouds simulate space environmentPlace inside vacuum chambersHelps the system reach equilibrium temperatures
(Angstromengineering, 2010)
ExperimentationResearched Thermal Shrouds
Material properties / liquid nitrogenCreated a thermal plate prototype for testingAdjusted thermal plateCreated a thermal shroud for thermal systems detail design group
Thermal Plate
¼ inch 2024 aluminum plate
Thermal Plate
Type K copper tubing½ inch inner diameter
Testing10 thermocouples placed on thermal plateDrop vacuum chamber to 0.038 Torr (pressure)Ran liquid nitrogen for one hourRecorded data from thermocouples

ResultsThermocouples and liquid nitrogen behaved as expectedThermal plate reached a temperature of approximately -250 °F
ConclusionFrom my thermal plate prototype Thermal System Detail Group was able to create a full size thermal shroud
