http://forum.wbfree.net/forums/showpost.php?p=706234&postcount=1 need an assistance in the form: Bf 109 E, 400 liters internal, xxx minutes, reference: @@@@@ P-47D-40-RE, 776liters main, 377 aux, ? minutes, reference: Joe Baugher http://www.joebaugher.com/usaf_fighters/p47_4.html etc
in common, may calс fuel consumption as 0.45 kg*hp/hour <add> minimal fuel consumption w/o prop and exhaust system, at low temperature, with pressurization, can be considered as 0.30 kg*hp/hour (0.28…0.32)
I think something might be there, but it's all in that weird language :-/ (unreadable for me) http://www.cockpitinstrumente.de/archiv/Dokumente/ABC/m/Messerschmitt/Messerscmitt AG.htm
May I use this formula to calculate fuel consumption and post it with the real ones? For example, what I found about Ki-44-IIc: Ki-44-IIc, 900km range, ? liters internal, 140 minutes, reference: http://www.savagesquadron.com/JPpage/JPFighters/Ki_44.htm, http://www.warbirdsresourcegroup.org/IJARG/ki44shoki.html With the formula (0.45kg*hp/hour): Nakajima HA-109 - 1,520HP 0.45kg*1,520/60 = 11.4 (is this right?)
A6M3 Model 32, 2377km range, 545 liters internal, 261.6 minutes, reference: http://www.xs4all.nl/~fbonne/warbirds/ww2htmls/mitsa6m.html Using the brain and making some calcs: Maximum Range = 2377Km Internal Capacity = 545L It gives me 4.36Km/L 1h - ~544km/h = 124.77L consumed 545 / 124.77 = 4.36h of flight, wich is exactly 261.6 minutes I couldn't find this value using the formula, tough....
if the time is problematic, we can make following proposition: all engines have 300g/h fuel consumption per every cv/hp/ps (1000hp output will consume 300kg in one hour, equal to circa 370litres of kerosene). your calculations are wrong, because maximum range is developed at cruising speed with minimal expenditure of fuel per kilometre. dunno about model 32, but 21's cruising speed is 333km/h. i don't know power rating for cruising mode (+150mm 935hp 2500rpm is 100%mil, +250mm 1010hp 2550rpm is wep for sakae 12). also, a6m2 has 330l external tank ok, making very rough calcs: A6M2 model 21, cruising speed 333km/h, fuel consumption 0.3kg*hp/h, range 3100km, fuel mass (545l+330l)*0.8kg/l=700kg =3100km/333kph=9hours =700kg/9h=75kg/hour=75000g/hour =75000g/h/300ghp/h=251hp hmm... probably poor mixture must decrease consumption. having 200ghp/h we'll get 376hp, that sounds more reasonable. but anyways, if we get correct internal fuel capacity, we can make endurance more proportional to IRL. long story short format needed: model, fuel capacity in litres (don't give me gallons, folks, cause you probably won't know whether it's yankee's or tommie's) example: A6M3 model 32, 545L Bf 109 all, 400L ....
Here exec, hope this helps, actual charts from manuals and pilots notes http://www.zenoswarbirdvideos.com/Images/P-47/47FOIC.gif http://www.zenoswarbirdvideos.com/P47Stuff.html
Charts from the F6F actual manual http://www.zenoswarbirdvideos.com/More_F6F_Stuff.html I have a question exec, why does the current F6F-3 have wep? should be with the F6F-5 ?
fas analysed R-2800-10 and found out that it actually has wep mode. meanwhile, wep with water injection of R-2800-10W is more powerful. however, he could not answer about R-2800-21 and R-2800-8
0.45 coeff for non-pressurizired low-octane benzin engines for aircraft eng. more suitable 0.3…0.35 @ sea level For HA-109 1520 hp it's take-off mode, max power at 5km 1300 hp Ki-44-II contain 455 liter fuel internal, max/cruise speed 600/400 kmh, max time 135 min (900 km range). So, 455*60/135≈200 l/hour=150 kg/hour. Approximately, cruise power≈1300hp*(400 kph/600 kph)^2≈580 hp 150 kg/580 hp=0.26 kg*hp/hour @ 5000m
Exec, one question: do u want all planes of FHL currently? What about an index at the first post just do help making it easier to find? Like this: Ki-44-IIc = HA-109, 1300HP, 455L (internal), 135-140 minutes
