Design Analysis of a Particle Thermal Radiator for Space Vehicles
Abstract
The design of a new type of thermal space radiator is extended. Micron-sized particles are heated and electrically charged on a high potential spherical electrode and ejected into space. A second high potential spherical electrode of opposite polarity attracts these particles and changes the polarity of their charge upon contact. The particles then return to the first electrode to complete the cycle. Along their trajectories the particles radiate thermal energy, giving a high area-to-mass ratio because of their small size. Equations are presented which permit calculation of power radiated-to-mass ratios for the entire system. Results of a computer study indicate that at power levels above one megawatt the new type of particle radiator will weigh approximately four to eight percent of the weight of its conventional tube-and-header counterpart. Limitations of the theory are investigated and discussed.
