MiG-3

 

MiG-3 is an upgrade of the MiG-1 fighter. Design and development of the aircraft belong to the OKB im. Mikoyan and Gurevich. It is a single-engine high-altitude one-engine fighter-interceptor, created during the Great Patriotic War. The AM-35 motor developed by A.A. Mikulina, the takeoff power of which was 1350 hp Although the takeoff weight of the car was large enough (3350 kg), its speed at the ground reached the value of 500 km / h, and at an altitude of 7000 m was 640 km / h. Compared with all the serial planes of the world at that time, this was the highest speed. The maneuverability of the fighter at altitudes above 6000 m was also the best among the analogs. The future of the plane promised to be successful.

History of the MiG-3

The first flight was made fighter 29.10.1940 running a test pilot AN Ekatova. In late December, the aircraft was sent to state tests. However, it began to actively deploy into production, and has already 9.12.1940 order of the government, he was replaced on the conveyor serial MiG-1. By the end of the year at the plant № 1 20 Aviakhim were built serial MiG-3. In accordance with the production program planned to release the aircraft in the number of units per 3500 1941, at the main plant and further 100 units in Kiev.

Tests of prototypes of the aircraft were completed in March 1941. Production models of the MiG-3 were submitted for testing. Test pilot A.G. was instructed to test the combat vehicle in action. Proshakov and military engineer A.G. Kochetkov.

After completions increased take-off weight of the aircraft, which has a negative impact on the flying machine data. Nevertheless, at the height of 7800 m plane outstanding performance speed equal to 640 km / h (prototype version - 636 km / h). Carrying capacity of the serial version was much worse. The serial version of the MiG-3 8000 was climbing m almost 2 minutes. longer than his experienced predecessor.

Test pilot that the aircraft was tested in comparison with the MiG-1 noted that during the execution of aerobatic plane was almost identical to its predecessor - easy to drive and predictable. Nevertheless, a large load leads to more congestion in the control room, which quickly wore aviator.

Design and armament of the MiG-3 were reliable. During the passage of the test did not have a single emergency due to damage any components. Claims were not also to the bomber armament.

MiG-3 cabin

The equipment serial MiG-3 included radar RCI-3, which allows you to receive signals from up to 150 km - higher than that of prototypes.

However, tests on all errors were found. Bending of rotor blades was placed at an angle 20 °. This made it possible to spin the engine over allows values ​​and could cause an explosion or fire power plant. The solution found in the selection of a new propeller.

Disadvantages of the MiG-3

As a modification of the MiG MiG-1-3 tried to create, thus eradicating the shortcomings of the basic model. However, not everyone was able to correct the error. The aircraft has a large landing speed - 144 km / h, the lack of maneuverability and a large radius bend. For other disadvantages include a low fire hazard and engine service life (up to 30 flight hours).

MiG-3

After the start of World War II, it became clear that an advantage in the air will have aircraft capable of effectively conduct fighting at close to medium range. Alas, the MiG-3 not apply to such units. Having a large take-off weight, he could not maneuver freely in the melee. As a result, the Soviet Union suffered a huge loss of aircraft at the beginning of the war, and the aircraft was removed from the production, based on the inappropriate release further.

Aircraft

A worthy continuer of the traditions laid down in the design of the MiG-1. A fighter adapted for fighting at great heights and having passed thousands of battles of the Great Patriotic War is an excellent example of a weighed approach to the modernization of old models with increasing power and productivity. This aircraft received from the ancestor an aerodynamic body with a modified cabin and an improved engine, allowing to develop the speed to 640 km / h, which at that time was considered a world record. The main task of MiG-3 was the interception of enemy fighters. The aircraft showed itself most well in the battle near Moscow and in the fighting in Moldova, the Crimea and the Kuban. He managed to overtake bombers and enemy fighters and destroy them on the outskirts of the protected area. However, in the course of military operations, flaws were found that soon required elimination: low flight speed at low altitudes, wide turning and bending radius, poor maneuverability at low altitudes and fire hazard of the engine. These shortcomings led to great losses in the course of the war, and soon the plane was withdrawn from production and transferred to the air defense units for guard service at important facilities.
