The Klimov M-106 was an experimental liquid-cooled V12 piston aircraft engine intended for Soviet aircraft during World War II.[1]
Development
With the VK-105PF exhausting the potential of the M-105, Klimov prolonged its development into new VK-106 engine from 1941. Since air combat on the Eastern Front took place primarily at low altitudes (under 4,000 m {13,000 ft}), the new engine was built specifically for peak performance at those altitudes with a reduced compression ratio and a single-speed supercharger. Static testing was carried out from 27 October till 9 November 1942. Although reliable and easily installed in M-105-powered aircraft, VK-106 did not enter production because its cooling problems were not solved. Like M-105P, VK-106P could house an autocannon in the "vee" between the cylinder banks.
