A-26D/E Performance Figures

[Zipper730]

I'm curious if anybody has performance figures for the A-26D/E which seemed to differ in the fact that it had a more powerful engine, a redesigned cowling, and wide-chord blades. Does anybody have figures for maximum speed, what altitude this applies at, and so on?

Based on the data I have from a PDF "USAF~USN engine designations 9th ED (50-01-01)", the R-2800-83 was rated for 17500', but these figures are w/o ram compression.

Odd you should ask about the D/E, the two I have not found.

Hey CORSNING,

I do not think that the XB-26D or E ever moved beyond prototype stage. There were only 2x (3x?) XB-26D built, and only 1x XB-26E (I think). Would there necessarily have been any SACs put together?

According to Baugher, only one XA-26D and XA-26E were built.

The A-26B and C had the R-2800-27 which was combat rated at 2,000hp @ 1,500ft and 1,600hp @ 13,500ft. Normal rating was 1,600hp at 5,700ft and 1,450hp @ 13,000ft.

The R-2800-83 of the D/E was combat rated at 2,100hp @ 3,000ft and 1,700hp @ 16,000ft. Normal rating was 1,700hp at 7,300ft and 1,500hp at 17,500ft.

White has performance numbers for the A-26B, C and and B-26K.

The B-26K has an even more powerful engine, 1,900hpat 7,000ft and 1,700hp at 14,500ft normal, maximum power 2,300hp (dry), top speed improved by a few mph but at a 5,000ft higher altitude. Climb performance was substantially increased, as was ceiling and cruise speed.

Was the top speed figures with water injection or without? Based on the cube rule, depending on that, the performance without water injection could be as low as 385.5 to 421.3 mph

White has performance numbers for the A-26B, C and and B-26K.

Who's White?
