RM8 vs TF30
Hi
I've been watching a bit about the F111 recently, (Jeff Guinn on Aircrew Interview), there's always a comment made about the TF30 being a bad example of an afterburning turbofan. However the Viggen with its RM8 was an afterburning turbofan. As I understand it, and this is very basic, the Swede's grafted an afterburner onto an existing civilian turbofan, (JT-8D). Does anyone know why the Swede's didn't run into the same sort of trouble as P&W did on their TF30, or did P&W driven the Swede's in a direction that was the result of what they had learned on the TF30?
