The Allison V-1710 aircraft engine was the only indigenous US-developed V-12 liquid-cooled engine to see service during World War II. Versions with a turbosupercharger gave excellent performance at high altitude in the twin-engined Lockheed P-38 Lightning, and turbosuperchargers were fitted to experimental single-engined fighters with similar results. The US Army preference for turbosuperchargers early in the program meant that less effort was spent on developing suitable superchargers, and when smaller or lower-cost versions of the engine were desired, they generally had poor performance at higher altitudes. The V-1710 nevertheless gave excellent service when turbosupercharged, notably in the P-38 Lightning, which accounted for much of the extensive production run.

Famous quotes containing the word allison:
“The horror of class stratification, racism, and prejudice is that some people begin to believe that the security of their families and communities depends on the oppression of others, that for some to have good lives there must be others whose lives are truncated and brutal.”
—Dorothy Allison (b. 1949)
