Abstract : The subject contract was initiated to optimize the design and to determine the performance characteristics of a heat pipe as an efficient means of transferring heat from a fossil fuel flame to thermionic energy converters. A theoretical analysis of the heat pipe was performed and experimental data is being accumulated to verify the theoretical conclusions. During the Final report period, progress was made on the following tasks: the redesign of the barrier eliminated cracking in the heat dam section; lead will not wet the alumina and therefore is not a satisfactory working fluid; and techniques were developed which produced uniform pore size in the wick structures. Permeation testing determined that of the combustion products of the fossil fuel flame, only small quantities of oxygen passed through the barrier. (Author)
