Ah yes, yet another "what if" project!! Have done much the same in desktop "doodles", but rather than taking the gas generator completely out of the loop, my "bypass relief doors", situated just foward of the HP compressor, opened outward, thus allowing excess air to go around and into the ramburner through what was otherwise the fan exhaust duct, while a "smidgeon" of the remainder still went through the core. My theory was that, by providing such a relief, both the quantity and the ambient pressure of the air just foward of the core would be reduced, allowing it to continue to perform some useful function, however limited, throughout the envelope, including accessory drive. That way, one can have it all, fan thrust at takeoff and climb, with gradual transition to ramburner as the mach number mandates. Again, "what if........................................."
