Yakovlev-30

 

Plane-30 and a fighter of World War II era. This unit was developed design bureau Yakovlev only two copies. In various sources, he is designated as the Yak-3 or I-26U.

Tests and fighter-30

For the first time, the I-30 aircraft broke away from the surface of the airfield at the end of the spring of 1941 under the supervision of the test driver P.Ya. Fedrovi. The first flights were successful, and the car showed excellent flight performance. The disadvantage was only the unreliable engine of the M-105P model, which was developed for flights at high altitudes. Soon the engine of such modification failed, after which the usual engine M-105 was installed. After that, most of the problems were solved. During testing, the fighter showed excellent maneuverability, which confirmed it as a quality combat unit. The device slightly did not hold out on high-speed indicators, especially at altitudes in 5 kilometers.

A year later it was made and the second model-30. The main difference from the first product was the bow construction because it was redesigned air intake. Tests of the second prototype took place without incident, which allowed to talk about the serial production of the aircraft. Chief designer Yakovlev persuaded senior management and put-30 on serial production only under the designation Yak-3.

Produce this unit is planned at the same time at three plants were even worked out the details and technical inventory of the aircraft. Despite this, in 41 year and it has not begun manufacturing And-30 because of the outbreak of the war, with the result that the project was shelved. All worked details altered to other machines, and finished samples were sent for scrapping.

The plane is made under the scheme nizkoplan with all-metal construction of the fuselage. This machine was able to remove the chassis in the middle of the body during the flight. Farm machinery was produced by welding steel pipes, which created the frame of the aircraft.

The nose part of the aircraft was equipped with removable hatches made of duralumin. These covers made it possible to quickly and easily reach the main parts of the power plant. The tailboard was made of plywood, which was attached to the pipes of the farm. All the wooden parts of the cladding were covered with linen. The wing was made of metal and was a double-lined structure. On the wings were installed two detachable consoles. The slats were automatic, and automatic flaps consisting of four sections were also installed. The ailerons were equipped with a metal frame with a linen hose. The left wing aileron had a trimmer in its design.

The plumage was both horizontal and vertical structure and were made of RAF-30 profile. The tail fin of the aircraft and stabilizers composed of two spars, which were made of aluminum tubing and over the sheathed blade.

chassis system has been represented by three pillars with telescopic shock absorbers liquid-gas type. Wheels to the uprights joined console mount. Release exercised chassis system that runs on compressed air. Stop the machine when planting carried out brake and brake pads.

Initially, the power plant was presented to the engine M-105PD who had a supercharger model E-100 to fly at high altitudes. During test flights this unit demonstrated its unreliability, when he was replaced by a standard engine model M-105P. On a jet exhaust nozzle installed with a fairing.

As for the weapons, it was represented by three 20-millimeter cannon type ShVAK on 360 rounds each. The structure of weapons and fighter-30 was included one machine gun caliber 7,62 mm.
