A Nuclear-Thermionic-Ionic Propulsion System
An electrical propulsion system for space probe missions to remote points in the solar system is described and analyzed in regard to feasibility and capability. It combines a nuclear reactor heat source with thermionic electrical power generators to provide requisite power for a cesium ion rocket motor. By the use of static techniques for transport and conversion of energy, the design emphasizes the avoidance of mechanically moving parts as major links in the transfer of power from the nuclear reactor to the ion motor so as to achieve maximum reliability for prolonged unattended operation in space.
