Limitations in variable conductance heat pipe performance and control predicted by the current steady-state model developed at NLR

A uniaxial model for the transient performance of gas-loaded variable conductance heat pipes is being developed, partly under contract with the Netherlands Agency for Aerospace Programs NIVR. The model has to be easily implementable in existing spacecraft thermal analyzer computer programs. So far, a steady-state version of the model is...
