What widely used on aircraft in the 1930s through 1950s was the result of the development of the M-25?
Shvetsov ASh-82 The Shvetsov ASh-82 (M-82) is a Soviet 14-cylinder, two-row, air-cooled radial aircraft engine developed from the Shvetsov M-62. The M-62 was the result of development of the M-25, which was a licensed version of the Wright R-1820 Cyclone.
Davis wing The Davis wing is an aircraft wing design that was used for some time on a variety of World War II aircraft, most notably a number of designs from Consolidated Aircraft, the most notable being the Consolidated B-24 Liberator. Thicker and with lower drag than most contemporary designs, it allowed high speeds and lift even at high angles of attack. Its use ended almost immediately following World War Two.
