- Klimov VK-106
The Klimov VK-106 was an experimental liquid-cooled
V-12 piston aircraft engine intended forSoviet aircraft duringWorld War II .Development
With the VK-105PF2 exhausting the potential of the M-105,
Klimov designed a new VK-106 engine in 1943. Since air combat on the Eastern Front took place primarily at medium altitudes (under 4,000 m {13,000 ft}), the new engine was built specifically for peak performance at those altitudes with a reducedcompression ratio and a single-speedsupercharger . Although reliable and easily installed in M-105-powered aircraft, VK-106 did not enter production because it differed from M-105 enough to require new tooling, and Soviet engine factories at the time lacked the capacity to produce another design. Like M-105P, VK-106P could house anautocannon in the "vee" between the cylinder banks.pecifications (VK-106P)
