A nuclear fusion propulsion system for spacecraft.

What is it about?

This paper discusses the design of the heat engine for a compact nuclear fusion propulsion system. The heat engine converts waste energy into electricity to both drive the engine and provide power to the spacecraft.

Why is it important?

The propulsion system in this paper is unique in that it has the potential to have a much higher thrust power to mass ratio than other concepts. Its high exhaust velocity and power to mass ratio would enable new ambitious robotic and human space missions.
