REMN+

REMN+ Version 13 is a governed cyclotron-nozzle hybrid that integrates four H₂EM engine cores, dual-stream collimation, CCR-A/B/C copper beam conditioning, rotating magnetic-field coils embedded within a rotating permanent-magnet assembly, CRX-derived throat governance, and magnetic-nozzle extraction. Optional 30–40 T REBCO inserts are a local, validation-gated throat capability rather than demonstrated flight hardware.

The proposed space-propulsion envelope is constrained by P = ½ṁv². The published analytical surface distinguishes a 2,000–8,000 km/s propulsion regime, where megawatt-class input can support 0.1–1 N class thrust, from an 8,000–20,000 km/s accelerator regime where microgram-per-second mass flow limits thrust to the millinewton scale. These are analytical design regions pending staged experimental validation.
