Kossov was a Shvetsov collaborator before WWII in the development of the M-11 5-cylinder radial.
-He also collaborated with the MG-11 that gave 165 hp and the 180 CV -F version.
-“MG” means “Motor Grazhdanskiy” that is, “Civil engine”.
-The Kossov M-12 was an improvement of the M-11, with five cylinders as well, but giving 190 CV.
-Below we see it installed in a Yak-18 but noting that the engine hood is like that of the Yak-11.
“Yak-18 with Kossov M-12 engine”
-Normally this plane would be powered by an Ivchenko AI-14R that gave 260 CV.
-With respect to the M-21 of 1938, this 7-cylinder engine was also improved by Kossov up to 220 CV.
-The 9-cylinder MG-31 radial engine from 1938 reached 300 CV and the -F version 330 CV.
-The engine known as MG-40 was an M-11 that was improved by Kossov for 140 CV as well.
