ge90-115b flat rated?
Is the ge90-115b flat rated to say 90000lb of thrust or is it capable of actually producing 115000lb of thrust assuming no limitations with high OATs.

Perhaps a review of the meaning of flat rated thrust will help. I don't need to spell it out - someone's already done it:And yes, gas turbine engines are capable of more thrust on a cold day (surprise, surprise), but will encounter turbine temp or RPM or other limitations in hot day conditions. The -115B produces 115K# up to a corner point (30C I think) but it's cut back above that corner point.

Yes, rated at 115,540 lb for takeoff up to 30C.

Isn't that nice, Dave had the commonsense and civility to just give an answer.
Grivet could take note. |
Can someone provide a LINK to a document stating flat rating is ISA + 15 for these engines?

Except that the link provided in post #2 doesn't actually answer the OP's question about flat-rating.
|
so would i be correct in saying that the 115b is flat rated to 115000 lb/thrust although it theoretically is capable of much more if no limit was placed up to ISA+15?
Im assuming this is to protect the engine from unnecessary wear as the 300ER would never require more thrust than this amount? |

The 777-200LR uses the same -115B engine.
Its nonstop ferry range from KORD for example can take it to ANY international airport in the world, with one exception: Perth, WA. Now tell me, once more, why you want more thrust? |
