Thank you! This kind of a case design is excellent and one can learn so much from it!
It uses regular turbofans + a hydrogen ramjet A GE "turbofanramjet" - a turbofan at low speed and a ramjet with a windmilling fan at high speed. Cruise point is Mach 6 at 30 km height and range is 12000 km (takes a bit over 2 hours). Most of the wing-body is fuel.
