Yakovlev UTI-26 (Yak-7UTI)


Yak-7UTI, or as it is called, UTI-26, a plane, which is actively used during the Second World War, Soviet pilots. This machine was designed by Yakovlev Design Bureau. The main task of this unit has been training pilots or borrowing their qualifications. On this machine were trained mainly future fighter pilots. She began to be produced commercially to 1941 years 186 just been built vehicles. End of designing fell on the summer 40 years, in the same year was built the first prototype.

Design features of UTI-26

Training aircraft type UTI-26 is a double unit, which was equipped with a screw motor. Due to the fact that the aircraft had two seats for the pilots, they can control each of the pilots, for that all control systems are duplicated. This machine is a low-wing monoplane.

Power plant machinery was represented by one air-cooled engine M-105P, it had a capacity of 1050 horsepower. This motor drives the screw, which consisted of three metal blades. Yak-7UTI had a screw diameter of 3 meters and designated as VISH-61P.

The cockpits of the pilots were arranged in tandem and had a lantern that was made of plexiglas. To get the pilot into the cabin, the lantern was equipped with a movable part that opened back. The front cabin was designed for the student, and the instructor was located in the back. The entire inside of the car was made in the same way as the I-26 fighter, which allowed the students to get more fully acquainted with the machine on which they would fly on combat missions in the future. Talks between the pilots were carried out with the help of gestures or a negotiation hose, later models were equipped with a SPU-3 talker.

Navigation equipment was quite primitive and mainly the pilot had to navigate on land targets. This machine can only be used during daylight and in good visibility behind.

The history of the unit UTI-26

This training machine has been manufactured on the basis of fighter I-26. Because of this, these machines have many similar structural parts. This was done for the most realistic training pilots as they prepared to fly fighter planes.

After making the first training unit was transferred to the factory tests, which took place in the summer of 1940 years. After the factory test car was handed over to the State Commission for further testing. When the state testing machine was damage to the chassis, because of which the tests were interrupted for two weeks. Despite the damage, the car completed the state testing by the end of autumn 40 years. The State Commission has confirmed the suitability of the device, and recommended it for serial production.

After the plane UTI-26 based at the Research Institute of the Air Force, where continued flight testing. Test pilots have worked all flight options and determine which is able to maneuver the machine.

Production aircraft UTI-26 were equipped with the best equipment and more reliable than the first devices of this class. Thus, serial training aircraft had not retractable landing gear, which allowed to increase the safety of pilots during landing. There was also an elaborate system that regulates the temperature of the VMG, the cooling was carried out by reducing the engine speed to 2350 / min. Also, the machine gun was mounted type ShKAS, enclosing five hundred rounds of ammunition.

Yak-7UTI maybe created as a learning machine, but the ego figures and significantly increasing application showed that he can do much more than simply to carry out training of flight personnel. Ego can be used even as a scout, as high-speed performance and high maneuverability make the ego hardly vulnerable to enemy fire. But he did a lot of names for pilot training before they sit down in combat vehicles.

As an experienced designer light gliders, AS Yakovlev was well aware of the important part played by the professional training of flight personnel. Progress in the development of the aircraft led to the fact that at a certain stage of training for future combat aces only Slower biplanes loses all meaning. It requires special transitional type of aircraft, ensuring the fastest possible adaptation of the young pilots to modern technology.
Therefore, when designing the first fighter in the design bureau A. Yakovlev designers worked in parallel to create an educational and training option. At first it was called UTI-26, and then after a number of improvements it got its own name - Yak-7UTI. The student's and instructor's cabins were located one behind the other, closing with a common lantern with independent moving planes. The equipment was duplicated, and its composition was close to the instrumentation of the combat vehicle and allowed to fly in the daytime on landmarks. The instructor was placed in the back cabin and monitored the cadets' actions visually or with the help of an intercom. With the outbreak of the war, the Yak-7UTI began to be used as a two-seater scout or a headquarters aircraft.

I believe that any training model of the aircraft should be equipped with a training version that will prepare young pilots for work with a particular vehicle. It was Yak-7UTI that was able to quickly prepare a huge number of pilots for military operations during the war with the Germans. Despite the fact that such models were produced in limited quantities and in a two-seated configuration for the instructor and the young pilot, the ego was widely used by the high command to independently fly around the territory of military operations. High-ranking officials chose this device for flights due to their high maneuverability and speed.
