Title: I-153 and the re-introduction of the gullwing Post by: warhawk on April 05, 2015, 08:51:46 PM If I understood well from the Red Star book, he I-15bis had a standard (straight) upper wing because some pilots had complained about visibility issues on the standard, gull-winged I-15.
Why was it re-introduced again on the I-153 then? Title: Re: I-153 and the re-introduction of the gullwing Post by: Massimo Tessitori on April 06, 2015, 07:05:28 AM Hi,
because the Soviet government had to admit that the increasing of weight and drag due to the traditional upper wing had made the I-15bis less performing than the original I-15.

Massimo Title: Re: I-153 and the re-introduction of the gullwing Post by: learstang on April 07, 2015, 04:23:06 AM I also believe, no doubt due to performance issues, that Nikolai Polikarpov preferred the original gull-wing. There wasn't much point in going to the trouble of putting a larger engine and retractable landing gear on the I-153, if you then counteracted those speed-improving measures with the extra drag of the traditional straight upper wing.
