Nuclear Thermo-Electric Thruster

Abstract

We present a theoretical analysis of an innovative combination of a nuclear thermal and electromagnetic (EM) thruster. Specifically, we scrutinize the thermodynamics involved in integrating a nuclear thermal reactor with an expansion turbine. This configuration facilitates the generation of substantial electrical power, which is then utilized to power an EM thruster (similar to an afterburner). This process results in a notable increase in the ISP from 900 to 1200 without the necessity for thermal radiators. Furthermore, by incorporating thermal radiators, the ISP can be further increased to approximately 4000. This enhancement allows for a significant reduction in transit time to destinations such as Mars and the outer and inner planets. We provide several examples to illustrate the potential applications of this innovative propulsion system.
