How to make B-17 fly at realistic combat ceilings
« on: December 12, 1999, 10:03:00 PM »
These B-17s currently in AH flies through the climbing and even mission with full throttle, which gives em alot benefit at higher altitudes and climbing performance.
If we take a look at real B-17, it is not possible to keep throttle 100% all the time or engine overheats (if I do remember correctly, 80-90% throttle was maximum safe throttle, higher could overheat engine so that it would flame out or cut off)
If B-17s in AH should lower throttle to 80-85% at times to cool down engine, it would greatly reduce over 30k B-17s which I doubt are realistic with combat ceilings. (nor that they climb like rockets all the time)

My two pennies worth...

The unheated guns (and crewmen) would be freezing at 30k too I guess

Quick stop gap would be to make Norden less zoomable. If they wanna hit the target, make them come down.

But then again, without structural limits, they could nose down and dive from stratosphere to bomb, and climb back after the pass.

I had a B17G dive to the deck from 20k, trying to evade me today actually...

Listen to this:
"In shallow turns load factors are small, but this increases as the turn gets steeper. Banking at 10 degrees produces a load factor of 1.5, but at 70 degrees this becomes 3.0. In a heavily loaded aircraft this could cause structucal failure."
If they would model that, no more weirdo fighter B-17s...

Next quest, find the ack:
 
I'd guess this is taken from 20,000 to 25,000ft, after bombing recon picture.
Can't see much acks or little buildings to pinpoint bomb with 1 bomb huh?

Load factor is equal to the inverse of the cosine of the bank angle.  A 10 degree bank has a load factor of 1.015, not 1.5.  A 70 degree bank has a load factor of 2.92.
