Why did I miss this thread... very cool discussion.
I have a PDF here about the Jaktviggen and looks like the RM8B produces around 203kN (45,740 lbf) at Mach 1.1. This is ridiculous! Just like the FF, 115,265 lb/h.
The Viggen intake system works really well at transonic speeds, especially at .9 and 1.1. Very impressive how the airframe is able to do that. Ram recovery is certainly very well used here.
About the F110 Fuel flow, at sea level, standard day conditions, the F110-GE-400 (based on -100) producing a thrust of 26,950 (static thrust), it has an SFC of 2.104 lbs/lbf/h. Which gives me a fuel flow of 56,702 lb/h.
The RM8A at Mach 1.1, sea level, shouldn't it make around 160 kN instead?
