The aircraft type MiG-1 was established as the first fighter known designers Mikoyan and Gurevich. This machine has other designations, such as "product 61" project or "X", a well-known name and it was-200. This machine was the first high-speed fighter, which was created by Soviet designers.
The history of the MiG-1
The new fighter began designing in the design Polikarpov bureau since November 1939 years. The new product is planned to be used as a fighter that has to be different high-speed flight. For this reason, much attention has been paid to aerodynamics designers housing. To improve the aerodynamics of the machine using a new material and high quality polished paneling machine. But as is known, the speed of the aircraft is mainly responsible power plant, which in this fighter was powerful enough at that time. All this should provide high speed and excellent control of the aircraft.
Designers achieve planned airspeed in 670 km / h, with a practical ceiling flight should be at least 7 kilometers. The machine could perform military tasks such as attack or fighter escort over long distances. It is said that almost all the designers of the plans have been implemented in the new fighter.
At the end of the year 39 was approved layout MiG-1, and the next day, the designers started working drawings. In order for the aircraft was made as quickly as possible, it is connected a large number of workers from different industries. In addition, production was carried out in two shifts, and even a week.
After purging the first plane layout, it became clear that the designers thought was excellent aerodynamics of the machine. These studies have confirmed the usefulness of the project, and he was sent for further manufacturing. The joint fruitful work of designers has led to the fact that in February 40 years 1 MiG-was transferred to serial production.
For the first time this fighter was presented to the public in the summer of 1940 years at a military parade in Tushino. In the first year of serial production 100 machines of this type were built, and the following year were ready 89 devices.
The test apparatus MiG-1
In the first factory tests, it was clear that the car has reached conceived by designers of high-speed performance. In May, the MiG-40 1 reached a top speed of 648,5 km / h, these figures were obtained on the altitude in 6,9 kilometers. The second instance of the machine, which was tested and showed an even greater rate in the 651 km / h. With regard to the maximum altitude, it was equal to 8,5 kilometers. But there were rumors that the car could go up to a height of more than 11 kilometers, but documentary evidence that does not exist.
Mounted on the MiG-1 engine it was not always reliable and sometimes aggregate could sum pilots. Besides capricious temper, the engine also demanded replacement of motor spark after every three hours of flight, it was too inconvenient. That is why at the end of the year 40 designers began testing a new, more reliable engine type AM-37. This power unit is different in that air is fed into the carburetor of the blower unit, wherein the air has been pre-cooled radiator with aq. Also, for cooling water two vodoradiatora Nine were installed. Furthermore, the motor used for this new type of screw VISH-61, which could change step. But this practice is not crowned with great success, since even at the height of kilometer 4 engine started shaking and almost stalled.
Design features of the MiG-1
The aircraft had a design that is very much like airplanes and-16, but there were a lot of differences. new fighter fuselage was made by design scheme plan. The tail of the car is made as a semi-monocoque, which had the additional fastening of wooden frames and stingers. Middle and bow sections of the device are presented removable engine mount, which was welded from tubes and covered with sheets of duralumin.
aircraft center wing was constructed as an all-metal construction. Besides metals, included in the tree structure of the machine, from which were manufactured console wings, resulting in increased reliability and lower weight of the wing. Designers had to use wood because of an acute shortage of metal.
The power plant has been presented powerful enough, but at the same time heavy engine type AM-35, which should work well at high altitudes with low oxygen content in the air. This engine could give power 1200 horsepower, but it was achieved at altitudes of more than 5 kilometers. The most efficient flight was at an altitude of 7 kilometers or more, where the MiG-1 could reach the maximum speed performance. The closer to the ground flying machine, the worse were the characteristics of the flight.
With regard to the fuel system, the aircraft type MiG-1 it was represented by two tanks, which were placed in the center section of the wings. Further this type of aircraft were equipped with extra fuel tanks for greater range.
In addition to the merits, the plane also had shortcomings, the largest was the construction of the pilot lamp, which reclined side. This opening of the scheme has led to the fact that during the flight the pilot could not open the car lights. Window shutters, which were to provide ventilation of the cockpit, working ineffectively and can not provide adequate ventilation and cooling in the cabin. These deficiencies have been finalized, and serial MiG-1 were equipped with a flashlight, which shifted back. Also, designers have provided a more efficient ventilation and cooling system.
All the shortcomings of the MiG-1 have been identified and developed by designers. This metamorphosis has led to the emergence of a new fighter, which was designated as the MiG-3, he also replaced the MiG-1.
