This image shows the detail of late type MiG-3. The large intake is for the left oil cooler tunnel. The small intake under the exhaust stacks should be for cooling the wires of the spark plugs. |
 |
The long fairings on the barrels of the side ShKAS 7,62 mm machine guns are characteristic of late type MiG-3s. This allowed to replace the ShKAS with two UBS 12,7 mm machine guns or even with ShVAK 20 mm guns. The central slot for UBS is not followed by any fairing. The couple of small slots should be both for guns cooling and for windshield de-icing. |
 |
Note that the intake lip of the right side oil cooler tunnel has a different shape from that of the left side. This was done to allow both intakes to captate air in the best way, because the air flow was put in rotation by the propeller. |
 |
|
 |
Note the metal sheet plates delimiting the upper and lower sides of the slots for exhaust stacks. One can vaguely see the actuating rod of the movable flap inside the oil cooler outlet. |
 |
The side plates behind the exhaust stacks were reinforced by a steel plate. |
 |
Each exhaust stack collects the fumes from two cylinders. The stacks are still new and shining. The movable outlet flap of the oil cooler is evident, as the triangular plates sealing its sides, that were introduced with late type MiG-3. |
 |
The fairing on the first exhaust stack was characteristic of late type MiG-3, and was introduced in production during the summer 1941. |
 |
The bubble under the nose is more protruding than on original MiG-3s, probably because of the use of an AM-38F engine from an Il-2 instead than the AM-35A utilized on MiG-3s. |
 |
The fast locks were introduced in the late type MiG-3s during the summer 1941. The earlier version was provided with Dzud locks on all the panels, and the engine cowling was scomposed in different way. |
 |
|
 |
This bubble-like protrusion should house the oil and coolant pumps. The hole provides some cooling. The bubble is higher than the original one.
|
 |
The oil coolers are visible inside their tunnel. |
 |
Here we see a thin lip covering the gap between engine cowling and prop spinner to prevent the access of snow. |
 |
The lip covers the upper and side parts of the gap, but it is not on the underside. It is partially overposed to the spinner. The asymmetry of the inlets of the oil coolers tunnels is evident. |
 |
The prop blade. It turns clockwise (seen from the front). |
 |
The intakes of the supercharger are located at the wingroots. A small door closes the intake when the engine is not running. This door opens by rotating backward on an horizontal axis located on its upper side. The door was introduced on late type MiG-3. The early model had only a grille. On the background, the flaps on the water cooler inlet are clearly visible. |
