ISBN-13: 9780897470254

Few plane designs have had as ordinary or advanced a historical past because the P-40 sequence. actually one wonders why the Air Corps elected to provide the H-75P a designation except a touch quantity within the P-36 sequence because it was once primarily a re-engined P-36A. Spin-offs from the P-36 layout might end result not just within the P-40 however the XP-37, XP-42, XP-46, XP-53, XP-60, and XP-62 plus those given Y designations and diverse sprint numbers.

Ignoring the Curtiss Hawk biplanes, the genealogy of the P-40 would appear to have its faucet roots within the XP-934 Curtiss quick of 1932 classic. even if a few event within the low-wing monoplane style used to be received while the corporate produced its famed Shrike sequence of assault planes, the fast, or XP-31 because it was once detailed by way of the Air Corps, used to be their first low-wing pursuit layout. by means of a kind of extraordinary quirks, the quick in the beginning was once powered via an in-line engine which gave solution to a extra strong radial, simply the opposite of the P-36 to P-40 layout improvement. The XP-31 used to be no longer profitable with both engine and the layout was once quickly deserted (It did earn the doubtful contrast of being the final U.S. pursuit airplane with a set touchdown gear). The Curtiss Company's fortunes took a downward flip within the pursuit box while the Boeing P-26A was once chosen by way of the Air Corps over the XP-31.
