FLAME HEATED THERMIONIC CONVERTER RESEARCH
Abstract
New types of welding techniques were developed for attaching the coated molybdenum thimble to the converter assembly. Although satisfactory temperatures and heat fluxes were obtained with burners using premixed air and gas, development was started of burners using fuel injected directly into the combustion chamber. Satisfactory burners employing fuel injection have now been produced. A number of anti-oxidation coatings for molybdenum are now undergoing evaluation, both in the form of coated wires heated electrically and in the form of thimbles heated internally with a flame. One thimble coated internally with TI-Kote was heated for 42 hr at a maximum temperature of 1400 C before failure occurred. Two flame heated converters were tested during this report period. Some power was developed but failure in the coating occurred before any data could be obtained. A model of a multi-diode power source using individually heated diodes is shown.
