Abstract
A technique is presented to test heat pipe equipped spacecraft under any operational sun angle and orientation without adversely affecting the S/C power and temperature distribution that can occur when heat pipes are tilted in a 1-g test environment. The proposed technique is based on a specially designed heater system to simulate the heat pipe performance (i.e. distribution of thermal flux and temperature). The heater system employs temperature predictions generated by computer simulation and a mathematical correlation of the performance of real and simulated heat pipes when operated similarly in a horizontal position.
