ShareThermal stratification of liquid helium in the SHOOT dewars.
Author(s) : TUTTLE J., DIPIRRO M. J., SHIRRON P. J.
Type of article: Article
Summary
During the 93-hour prelaunch ground hold, the liquid was thermally stratified. This stratification allowed for more efficient removal of the parasitic heat inputs. There were also temperature gradients in the dewars during the on-orbit pumpdown. The authors describe the liquid temperature profiles during ground hold and on-orbit pumpdown, discussing the effects of this stratification and comparing the performances of the two dewars. They also discuss the results of a computer model of the isothermal pumpdown of a SHOOT dewar on-orbit.
