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

Heat Transfer

BackgroundThermal Shrouds simulate space environmentPlace inside vacuum chambersHelps the system reach equilibrium temperatures
