Pulsed Plasma Rocket
A system that has the potential to produce 20,000 lbsf of thrust with an Isp of 5,000 s.
The system is derived from the Pulsed Fission Fusion concept but the Pulsed Plasma Rocket (PPR) is smaller, less complex, and more affordable.
A Brave New World of Propulsion
A system with 100,000 N thrust and 5000 s Isp requires a power source greater than 2.5 gigawatts. If EP, then roughly 10 gigawatts of thermal heat would have to be radiated- well beyond any system put forth so far.
Pulsed power generation allows high Isp and high thrust. As the system is not in thermodynamic equilibrium, the heat rejection can be accomplished.
An affordable, high Isp, and high thrust propulsion system to enable fast transits of humans to Mars in a shielded ship to protect against Galactic Cosmic Rays irradiation Transit times of 3 months to Mars with a water shielded ship are enabled with a single SLS launch PPR can provide large cargo transport to Mars as well as fast human transport
