Definitely worth a read. Thankx for posting this.

" Firing of the nose guns caused the buildup of carbon monoxide contamination in the cockpit, and this could reach a lethal level very quickly."

...could it have been really that serious? I don't recall reading anything about this before...

As a result of these qualities Airacobra was withdrawn from RAF service by the end of '41/i/smilies/16x16_smiley-very-happy.gif .
So much for those british tests.

The 109E comparison just reveals what we already new about the Cobra. It turns well and has good dive characteristics. The question I have is, how did the P-39 compare to the 109 and 190 in a climb?

Interesting. Thanks for the heads up.

Salute

As someone mentions, the chart in question shows the rollrate for a P-39D.

http://naca.larc.nasa.gov/reports/1947/naca-report-868/42.gif


The N model had a similar armament to the D, ie. 4 .30 cals. mounted in the wings.

The P-39Q1 had two .50's mounted in the wings, which were heavier than the four .30's.

The P-39Q10 had no wing guns, so should be considerably faster in its rollrate, without that inertia to overcome.

It is also clear that improvements were made to the P-39's as the war went on. The Soviets were very active in sending suggestions for improvements and changes to Bell.

One of the changes which differed the P-39N from the P-39D was the removal of four fuel cells in the wings which reduced the fuel from 120 gallons to 86. This shortened the range, but lightened the aircraft by approximately 350 lbs. It would be very likely that the removal of these cells would improve the rollrate.

On the other hand, it seems the Q10 model had the fuel cells added back again, bring the capacity back to 120 gallons.

My conclusion would be that the issue probably should be put to Oleg, but at the same time, it is quite possible that he has got it right already.
