Curtiss V-1570 Conqueror
The Curtiss V-1570
Conqueror was designed as the replacement for Curtiss' successful D-12 of
1922. The Conqueror went into production in 1926 producing 575 hp and was
producing 650 hp by 1931.
Although the Conqueror accounted for 2/3 of the Army's purchases of of
large engines as late as 1932, the Conqueror marked the beginning of the
end for Curtiss aircraft engines. Tests in 1931 showed glycol leaks and,
with a declining interest in liquid-cooling, funding was cut a year later.
