Long Duration Exposure Facility (LDEF) low temperature heat pipe experiment package (HEPP) flight resultsThe Low Temperature Heat Pipe Flight Experiment (HEPP) is a fairly complicated thermal control experiment that was designed to evaluate the performance of two different low temperature ethan heat pipes. A total of 388 days of continuous operation with an axially grooved aluminum transporter heat pipe and an axially grooved stainless steel heat pipe diode was demonstrated before the EPDS batteries lost power. Preliminary postflight tests showed that the heat pipes are still functioning. A summary of the flight data analysis for the heat pipes and the related support systems is presented.
