The Allison V-1710 was one of the most important large U.S. aero engines,
with over 70,000 engines produced from the time of the first in 1931 to the last
in 1948. The engine was produced in large quantities in the early1940's for
several important fighters of WWII including the P-38, P-39, P-40, P-51A,
P-63, and P-82. While the debate over the merit of air-cooled -vs.- liquid
cooled engines had raged in the 1920's, each was recognized to have certain
advantages.
As the only liquid cooled U.S. designed engine of the second-world war (the
Rolls-Royce licensed Merlin being the other significant liquid cool manufactured
by Packard as the V-1650), the V-1710 exhibited the advantages inherent with
liquid cooled engines.
These advantages include low frontal area and high short-term peak power
output thanks to the coolant heat-sink, higher power because of the greater heat
rejection capability of liquid coolant, and packaging flexibility. The
air-cooled engines advantages are primarily the weight savings and reliability
inherent in eliminating the liquid cooling system.

ManualThe Allison V-1710 aircraft engine was the only indigenous
US-developed V-12 liquid-cooled engine to see service during WWII. A
sturdy and trustworthy design, it unfortunately lacked an advanced
and efficient mechanical centrifugal supercharger. Versions with a
turbo supercharger gave excellent performance at high altitude in
the twin-engined Lockheed P-38 Lightning, and turbo superchargers
were fitted to experimental single-engine fighters with the same
excellent results. View:

(1942) This Allison V-1710 Operators manual details subcomponent system
problems and maintenance of the legendary WW2 engine as well as
lubrication and electrical connections. The " Allison" V-1710 has 12
cylinders with a bore and stroke of 5.5 by 6 inches
in 60? V-format, aggregating to 1,710 in? total displacement,
with a compression ratio of 6.65:1. View: Allison V-1710 Operators manual (1942) | |
