Yakovlev Yak-19

Yak-19, which is the codification of NATO called Type 7, is an experimental fighter aircraft development Yakovlev fuselage with the scheme. Also, this is the first all-metal fighter Yakovlev development. The first flight took place in the early 1947 2, the total manufactured copies.

According to the requirements of the government several OKB started to develop a new fighter with the engine design cradles the TR-1. In addition to the Yakovlev Design Bureau. Yakovlev Design Bureau began work Lavochkin OKB Mikoyan OKB Alekseev and Sukhoi.

Design and development Yakovlev Yak-19

The car for flight tests required to submit 29.10.1946. The design of the fighter was given only 50 days. Developed design Yak-19 3 chief engineer. At the initial stage of work on the Yak-19 was headed by L. M. Shekhter, then NK Skrzhinsky was put in his place, after which already in the pre-test periods this duty fell on the shoulders of L. L. Selyakova. The latter moved to Yakovlev KB from OKB-482 to 1946.


During the development of the fighter, the designers decided to abandon the redrawn scheme that was used on the Yak-15 and Yak-17. It was replaced by a fuselage (classical) scheme. The fighter was the first in the open spaces of the Soviet Union with a similar scheme, then it was taken as the standard in the production of fighters. Also, this aircraft was the first all-metal machine, created in the Yakovlev office. 27.10.1946 he was given the designation Yak-19.

Design Yakovlev Yak-19

As part of the armament Yak-19 received two cannons Sh-3-23 caliber 23 mm, designed by the designer BG. Shpitalny. The ammunition of each gun installation is 75 shells. It was on the Yak-19 that these guns passed state tests. The wing of the aircraft had a trapezoidal shape, a straight, double-spar, medium-spaced. Wing profile laminar, thin, had a relative thickness of 12%. In the wing fittings, the flaps of the TsAGI were used, which became the modified versions of the Fowler flap, and the ailerons of the Freize type. The cockpit was not sealed. As part of its armored part was 57 mm armored glass, 6 mm armor plate, 8 mm armored plate on the catapulted armchair. The chassis of the airplane was made three-way, retractable. Inside the fuselage, 2 fuel tanks were placed, the capacity of which was 815 liters of fuel.

Equipment Yakovlev Yak-19

Yak-19 equipped with radiopolukompasom RPKO-10M, the defendant "friend or foe" mid-3, 1200-GSK generator, battery 12-A-10, 22-fotokinopulemёtom PAHs and oxygen device KP-14 with a cylinder capacity of 2 l radio RSI- 6.

Tests Yakovlev Yak-19

Despite the fact that the structure of the aircraft had to use a large mass of innovative technical solutions, it still managed to build as quickly as possible. Work on the creation of the first instance has already ended November 29 1946 of Getting off the assembly line, the plane was immediately sent to the passage Khodinka ground test phase.

12.12.1946 after the first taxiing and testing of the systems onboard the Yak-19, a fire broke out, resulting in minor damage to the aircraft. After repairing the 8.01.1947, for the first time, the test pilot M.I. Ivanov. At the same time, the afterburner, specially designed for the Yak-25 fighter, was tested on the B-19J flying laboratory.


1.05. 1947 3000 the plane at an altitude of meters for the first time performed a flight in afterburner, and the rate increased by 90 km / h.

In the early summer of 1947, test pilot S.N. Anokhin began to conduct flight tests understudy Yak-XNUMHD. The main difference of the second car from the first copy was the presence of fuel tanks at the wing tips, the total capacity of 19 liters. In total, the factory tests were made 200 departures on the Yak-27 and 19 - on the Yak-37D. The total duration of the flights of experimental fighters was 19 hours.

3.08.1946 aircraft was demonstrated at the Tushino air parade and 2 months later transferred to the Air Force Institute for passing state tests, which started in October 17. Lead engineer was appointed VP Belodedenko, pilot - AG Proshakov.

In the final act of the state commission for passing the test experts identified a number of errors related to the complexity of managing post-combustion fuel, a lot of effort from the ailerons on RUS, lack of cabin heating and ventilation systems, insufficient armor pilot. Because such a vast number of design flaws Yak-19 was not recommended for mass production and formulation adopted.

For one "most-most" aircraft in the model range of products of any designer, there are always several machines that have not become widely known, made in single units, but without which the leader could not have taken place. Yak-19 - one of the projects OKB-115, laid and implemented by A.S. Yakovlev in the first post-war five years, and remained experimental. Released in only two copies, not accepted for production due to unavoidable shortcomings, the machine, nevertheless, can not be called unsuccessful. Much of this machine has been tested for the first time. The Yak-19 fighter is the first all-metal Yakovlev aircraft. Also, a transition was made to the fuselage layout, which became a classic, for the deployment of the turbojet engine, which in itself provided a significant improvement in the aerodynamic performance of the aircraft. Together with the engines, Yakovlev dealt with the issues of increasing the speed and takeoff and landing characteristics, taking over the development, creation and testing of the first afterburner at the Yak-19. Another innovation was the installation of a catapult chair for the pilot. Having surpassed the speed of the Yak-15 by more than 100 km / h and reduced the take-off / mileage by an average of 22%, the Yak-19 aircraft confirmed the correctness of the design bureau's transition to reactive engineering.

I have an active interest in aviation, both in our country and other countries and can say with certainty that this aircraft is the first Soviet jet fighter, which was made in the classical scheme of the structure of the body. Before the model Yak-19 jets is pleased to have the scheme, which was not very high quality and had many shortcomings. This machine has a long history of its creation, but it still takes pride of place in the line aircraft Yakovlev.
