KC-10 Maximum Unrefueled Range?

Thu Dec 09, 2004 4:31 pm

Hi,

Was just wondering if anyone could give accurate statistics to this question...both maximum possible (empty cargo, full fuel), and full cargo and fuel...

Thanks,

Well, as directed:

With 0 pnds cargo but 4 crew and max. fuel (356,000 pounds) the KC-10 can fly 10,000nm unrefueled.

With 170,000 pnds (MAX) of cargo and 356,000 pounds the KC-10 can fly 3,800nm unrefueled.

With 0 pnds cargo but 4 crew and 0 fuel the KC-10 can fly nowhere.  Smile

Without having a performance chart handy (like I ever read them anyway) the first number sounds about right. After GW1 10s flew Saudi Arabia/California non stop.

The second number is wrong with the fuel weights. With a max T/O weight of 590K here's approx what they should read;

Op weight=250K
Cargo weight=164K (can't carry more than this because the max ZFW is around 414K
Fuel weight=176K

Some jets are lighter, some heavier. But that's a not so rough guesstimate.

The last number sounds about right

How far can it fly with maximum fuel and then whatever additional cargo it can hold to get it to MTOW?

With max fuel it's not going to have any additional weight to spare for cargo. Because the MGTOW (which is also the inflight weight limit) is set at 590 the KC-10 can't even fuel up to 356K. I don't think it ever could-I doubt the 10 ever weighed 234K basic weight, let alone operating. 240 is the lowest I've ever heard. And that was from the 80s. Today, the average op weight for a "B" config jet (16 seats, 23 PPs), no pods, is roughly 250K. Add 340K fuel and you're at the max weight: 590K. That was the answer to the first criteria: max range unrefueled no cargo. 10,000 NMs sounds about right.. That's about 145 in the main tanks, 54 in the forward, 76 in the center and 64 in the aft.

Max cargo/ max fuel in a "B" config with a 250 Op weight. 164K of cargo, 145 in the mains and about 31K in the center. You can't really put alot of fuel in the forward and aft tanks because of zone load limits, ie, the aircraft's floor limitations. You can put alot of fuel underneath the floor or alot of cargo on top of the floor, but when you're hauling both you can carry less of both. It's a give and take: more cargo, less fuel in the Forward and aft tanks. More fuel in the forward and aft tanks, less cargo you can carry. For that, 3800 NMs sounds about right.

Edited for a stupid mistake
