LIQUID METAL-HEATED SPACE RADIATOR-MOUNTED THERMIONIC GENERATOR.
Abstract
Work was initiated to evaluate thermionic converters suitable for liquid metal heating in space radiator configurations. The design of the converter to be evaluated in this program was completed. The converter incorporates a Ta-10W alloy liquid metal containment tube insulated by BeO from a W-25 Rc emitter. A nickel collector with an inter-electrode space of 8 mils has been selected. The predicted performance of this converter indicates a power output of 4.7 w/sqcm with an efficiency of 12% when the emitter temperature is 1500 C. A bifilar tungsten filament was selected for use as a heater. (Author)
