Project Hot Shot - Particle Thermal Radiator

Abstract

The design of a new type thermal radiator is extended. Micron-sized particles are heated and electrically charged on contact with electrode spheres and radiate thermal energy during oscillations between spheres. Results of experimentation show that metallic particles will charge and the charge transferred (in coulombs) can be calculated from the empirical formula q 8.16 x 10-23 d2 ( ).12 E where d is the particle diameter in microns, is the particle electrical resistivity in micro-ohm om, and E is the electric field in volts per meter. Results of a computer study indicate, for power levels on the order of ten megawatts, the particle radiator will weigh approximately 16% of the weight of the conventional radiator.
