TF10000 is a different engine. It has to withstand the sudden jolt of the afterburner when it kicks in. Materials and parts used have to be different in places where it matters.Hmm, in this case, more than three prototypes may be produced for the TF6000. The engineer at the fair noted that afterburner is not an easy technology and that significant work has been done on it. Consequently, the TF10000's production schedule will likely take time.
If all goes well, the TF6000 is expected to be produced even sooner, as many prototypes have already been produced.
Prof Akşit had mentioned all this before.
