****... worked 3/4 hours to gather range.. lost it.
But I get 422 km or 262 miles radius for 109F-4 with above conditions. Cruise out - more. Say 500+ km. Can't recall. In back route, when fuel is less (used in combat). This is distance it can get back from, after going there, burning lots of fuel in combat (5+20min) and has reserve for 20 min mimum cruise too.
By crusing at 510 kph at 7000 meter and a droptank. With exact conditions shortround pointed out.
Conditions.
400 liter internal, 300 liter in drop tank.
1 - 30 min rating. 372 liter / hour.
2 - same.
3,6. middle cruising. 510 km/h. 210 liters/hour. see http://www.beim-zeugmeister.de/zeugmeister/index.php?id=22&L=0/
5, 5 minutes 445 liter/h (this is F-4 max. or WEP, 600+ liters is wrong,, correct for 109K), 20 minutes 372 lit/hour (this is F-4)
0-min)
7, 20 minutes minimum cruise. 130 lit/hour at 410 km/h. Actually I believe even less possible. see. http://www.beim-zeugmeister.de/zeugmeister/index.php?id=22&L=0/
I only counted cruise in and out, no distance in climb, or during combat power.
Actually, quick re-do. I only need to know what remains after combat, after drop tank jettison.
109F arrives interception point, drops tank, has 400 liter internal.
5 mins at 110% - 1350 HP. 445 lit/h. -37 liter
20 mins at 100% - 1200 HP. 372 lit/h. -124 liter
30 min minimum cruise reserve - 0.65 ata / 1500 rpm. 130 liter/h. 410 km/h. - 65 liter.
37 + 124 + 65 = 226 liter. Leaves 174 liter in tank. For cruise! Note we have still reserves, already calculated in.. 65 liter. Enough for 1/2 hour very economic cruise - + 200 km range. for safety. This is margin of error, manouvers in formation etc.
Cruise back at 510 km/h, 210 liter/h = 0.82 hour cruise = 422 km or 262 miles. This is radius 109F by US standard. also G - very similiar.
Note: if max. range cruise allowed, plane can still get back to base at 410 kh / 130 lit/h.
109K may be bit less. Actually, easy to calculate.
***5 mins at 110% - 2000 HP. 650 lit/h. -54 liter*** revise!!! this is SL consumption. 109K at 7500 m do not produce 2000 HP, so do not consume 2000 HP fuel, either.. possible up to 5 km, so this is low altitude consumption, inappropriate at 75 km..
5 mins at 110% - 1550 HP (6,8 km) or less. 525 lit/h. - 43 liter
20 mins at 100% - 1285 HP at 6.8km . 425 lit/h. -141 liter
30 min minimum cruise reserve - 0.65 ata / 1500 rpm. 130 liter/h. 410 km/h. - 65 liter. I take this same as 109F/601E.
Revised. 43 + 141 + 65 = 249 liter. Leaves 141 liter in tank. For cruise! Note we have still reserves, already calculated in.. 65 liter. Enough for 1/2 hour very economic cruise - + 200 km range. for safety. This is margin of error, manouvers in formation etc.
Cruise back at 510 km/h, 210 liter/h = 0.67 hour cruise = 342 km or 212 miles. This is radius 109K by US standard (apprx. Assumes cruise is same as 109F. This is likely assumption. High speed range - given as same by German datasheet for F, G and K. So things even out..)
Note: if max. range cruise allowed, plane can still get back to base at 410 kh / 130 lit/h. In this case it can cover 442 km. But this is not compatible with above us standard, still, a possibility.
However, if rear tank in use 109K (+115 liter), it still has 256 liters in tank. Enough for 1,21 h / 621 km (386 miles) at 316mph/510 km/h, OR 2 h/ 807 km/501 miles at slower most economic cruise 410 km/h.
Cruise out and climb, takeoff, all consumed from droptank.
Translate into real world for demonstration.
109F in Calais can operate in this conditions up to Leeds or Liverpool by US stanadard.
109K in Calais can operate in this conditions up to bit beyond Birmingham by US stanadard.
In defence,
Frankfurt is in mid-west Germany.
109F in Frankfurst base can just cover out to the Channel in Holland, North Sea shore of Germany Berlin, Prague, Bremen, Hamburg, Amsterdam, and Paris, and out to the Italian border.
109K in Frankfurst base can just cover Bremen, Leipzig, München, Brussel etc.
This by returning to same base it took off from. But realistically - there were dozens of other bases on route to land..
So I do not agree 109F-K range was insufficient for task. You wrote: "A Mustang using just the 184 gallon wing tanks was rated at 150miles. With rear fuselage tank it was 325miles." 109F 262 miles, 109K 212 miles. Compares well for its task. Of course this with droptank - but 109 almost always carried it.
