@Kreep2knight In the end it's up to you. Most people on here don't pay attention to fuel. Personally, I use extra hidden engines that activate automatically at 95% throttle. The extra thrust and fuel consumption seem more or less accurate like that.
@Kreep2knight @Aeromotive A Vietnam-era F4 could burn through hours worth of fuel in 10 minutes with the afterburner running. Each J-79 engine consumed just under 10 pounds per second with afterburner, and it had two of them. That's why midair refueling is so important for fighter planes.
@Aeromotive It depends on the engine design. In the case of the SR71 and the Foxbat, they were completely designed around using their afterburners to the fullest extent. The J58 is a partial ramjet because of its unique bypass system, but the Foxbat's engines were traditional after burning turbojets, just really really big ones. The thing about afterburners is that you can more than double your thrust with them under the right circumstances, especially with unburned air coming from a bypass. The downside is that afterburners use an astounding amount of fuel, as much as 385 gallons per minute.
@F104Deathtrap Alright so if I understand correctly; the core of the engine becomes less and less influential on thrust as speed increases past mach 2, turning it more into a ramjet. And wow I knew that aircraft was powerful but that's pretty insane.
@Aeromotive Yeah, past mach 2 most jet power comes from the inlet and the afterburner. The actual engine is just what you use to get there. The Mig-25 was the same way, except it didn't have a fancy bypass system. Fun-fact: the Mig could generate so much thrust with its massive afterburners that it could continue to accelerate past the point where the engines failed, melted and literally began to eat themselves.

@F104Deathtrap @Aeromotive I guess I could make my afterburners use a lot...

@Kreep2knight I know right that's about 6 gallons PER SECOND
@F104Deathtrap Blubbering... sputtering... Gulping... WHAT!!!!!!!!!!! That much fuel??!!
Demn, hence why it was good
@F104Deathtrap Fascinating stuff tbh

@F104Deathtrap Hah, so that's the reason it works up to mach 3.5 and 80,000 ft.
@Aeromotive I wish. Turbo-ramjet confirmed.
@jamesPLANESii Remember this next time you strap a J15 to something, it can power an SR-71 lmao
Oh sound. Yeah it does lol
Hmm you sure about that lol
