I got to looking into the Hispano-Suiza 12 Y engine series and it seems that the line took on a life of its own in Russia. The Soviet Union was licensed to produce the Hispano-Suiza 12 Y and the Klimov Bureau released it as the M-100.

The M-100 was improved into the M-103 and, progressively, into the M-105, M-105PA, M-105PF, and finally the M-105PF2 of 1310 hp. This engine turned into the VK-105.

So, just as the Merlin was one of the most-produced engines in the world, it now seems the Hispano-Suize basic design was used in most of the Soviet Union's inline applications.

I did not really know that the basic Klimov inline was a licensed engine ... and probably was built in greater numbers than either the Merlin OR the Allison.

Yeap, true.
Just VK-107 was absolutely different engine to M-105. May be that's why it didn't work properly! :D

M-105 all modifications for WWII were produced about 91000

Hi Capilatus!

Please tell me the Shvetsov wasn't a Pratt & Whittney!

Sorry!

I mean the Klimov 100 / 103 / 105 series was basically a Hispano Suiza, and I hope the Soviet radials were not developments of other radials.

My sources say they came from radial M-5 that was developed from captured American engine Liberty-12. The engine got very lucky 1917-1919 about 20000 were produced. Sure it pushed desiners to the better constructions like M-62 (I-15, I-153, I-16) and even still in use with An-2 biplane. Up to famos M-90 and M-88 (IL-4) and sure M-82FN (ASH-82) La-5,7 Tu-2. One of the best piston engines ever built. Though it was at the end absolutley new design in my opinion it couldn't be made without somehow captured Liberty-12...
