We reliably burn about a grand for a burner takeoff in an A-G config. That gets us from a dead stop to 350KTS at 2000 feet. We bring it out of AB usually at 300KTS unless the gear hasn't finished retracting, then we'll bring it out sooner. Both the PW220 in the Block 42 and the GE110 in the Block 40 burned about the same. The most fuel flow I've ever seen on takeoff was around 36K per hour. Why are you asking?
Hi,
If this is what you copied----it says a grand---ie 1000. So if it is a 1000 gals----then it is 3 times that amount of 7%---ie 21% and they normally climb to about 30000 ft and not 2000 ft.
But if 5 to 7 % is all they consume on an after burner take off with a full load and climb to their crusing altitude of around 30000 feet---we got our problems solved----let us get some more of those panes---.
Just a simple example----my Honda civic---give about 34 miles a gallon on regular driving surface streets-----. But when I am climbing up the hill thru Cajon pass at 75 miles and hour at 5000 RPM's in 4th gear---I am getting about 18-20 miles a gallon and still the engine can go up by another 2500 RPM's.
You guys want to try it on your own----just drive your cars in 3rd gear at 4500 rpms and see how these little cars become gas guzzlers---.
The bottom line question is----why would we need refuelers if only 5 to 7% of the fuel is used for take off----
