to the original thread discussing the SonicStar, a SSBJ using superconducting rim gas turbine engines.
Continuing onward from recent NASA studies regarding a superconducting rim driven fan, the S-MAGJET is claiming to be a new all electric hybrid engine. It appears the dual counterrotating fans, the compressor stages, and the turbine stages feature superconducting rims and a hollow core "shaftless" architecture. Because extracted power from the turbine stages is electric rather than mechanical, it becomes possible to electrically regulate the power split between fan and compressor in the engine, as well as operate fan/compressor RPM's substantially different from the turbine stage, as well as tweaking the RPM of individual stages. This may provide a means of providing variable cycle control. Substantial auxiliary electric power is also available for extraction (there is the implication that SonicStar may use plasma drag reduction techniques which would require substantial electrical power)
