Abstract : This report presents the details of a spin table test facility developed for testing heat pipes and other heat transfer experiments under high acceleration conditions. A drive system capable of variable spin up and spin down acceleration rates to simulate aircraft G-forces encountered during flight maneuvers is described. Also included are details on calorimetric testing, remote computer control operation and multichannel data acquisition capabilities of the spin table. The effects of G-load on a heat pipe performance were analyzed with reference to the influence of bond number and operating temperature. The steady state test results of a flexible copper-waterheat pipe under transverse accelerations up to 10G are presented along with those analytically predicted.
