Yakovlev Yak-36

 

Attack aircraft Yak-36, created by Soviet designers, the first prototype of the Soviet Union, which has a system of vertical takeoff. This machine had planned to use on aircraft carriers.

History of the attack aircraft Yak-36

The project began at the end of 50-ies in the design bureau Yakovlev. The main task was to develop an effective vertical take-off system. To implement these tasks in reality, engines like the TR-R-19-300 were developed. Originally it was planned to use two data of the engine with thrust in 3200 kgf and one marching power in 900 kgf. In parallel with this option, two more projects were developed with different arrangement of lifting installations. As a result of improvements, the designers received a new design of the aircraft, which was designated as "product B", and later Yak-36. At this time, the UK created a similar aircraft, but with a different arrangement of lifting equipment. The project was headed by S.G. Mordvinov with the support of engineer OA Sidorov.

Yak-36

For the first time in the air Yak-36 1964 year rose in the summer, but the flight began and ended with a running mileage. There was a vertical take-off, as designers could not accurately predict how the car will behave in such a flight. Soviet VTOL birthday is March 24 66 years since this day attack aircraft Yak-36 performed the first vertical take-off and flying a circle, and then made a prosperous vertical landing.

The general public is presented in a new car 67 year in the aviation parade in Domodedovo. Then the wings of the aircraft were fitted dummies possible weapons, it was done because of the light-duty machine. In the future, engineers have finalized a set of systems of ground attack that resulted in the receipt of such aircraft as the Yak-38. It should also be noted that based on the Yak-36 has developed many different versions. And the most important thing was that the Soviet designers have gained experience in creating aircraft with vertical takeoff.

Design features of the Yak-36

With the lifting and installation of the main engines on the apparatus needed to install the jet rudders. They had a great draft, one of them was located on the bar for the machine frame. This arrangement rudders help to keep the aircraft in hover. Propulsion motors were placed in front of the body, and their nozzles to be displayed on the center of gravity of the machine. To facilitate the work of the pilot's rudder is controlled automatically by the system. For ramp-up after lifting the machine performed turn the nozzles in a horizontal plane.

Due to this configuration of the power plant constructors were used bicycle landing gear. The chassis consisted of three pillars. Front support had driven one wheel and two rear support - on two wheels each. The machine frame is made of semi-monocoque scheme. Wings fitted with flaps spar. The innovation was to improve the ejection system in emergency situations. The evacuation was carried automatic pilot without his participation. There was a automatic control of the aircraft at near-zero rates.

For the tests, four Yak-36 aircraft were built, each to fulfill certain tasks. The first apparatus was used to test the strength of the structure, the second specimen performed tests for vertical take-off and landing. The third Yak-36 crashed during testing, it was during the landing that the chassis system broke down. Prior to the accident, he worked on the efficiency of the jet wheels. Due to these tests, it was possible to organize the optimal operation of jet rudders and to stabilize the machine on the hovering regime. The fourth car was used directly for flight tests.

Deck attack, the prototype of the first production aircraft with vertical takeoff and landing Yak 38. The idea of ​​creating a vehicle with vertical take-off was first implemented as a helicopter, but to build the aircraft with such capabilities failed. The matter was put in motion at the end of 1940 years after the appearance of jet engines. The first steps in the construction of such a device in 1947 year did engineer KV Szulik, the author received a patent for his invention. Later it was used in the English VTOL Harrier * * and domestic UC and UC 36 38.

I really like to get acquainted with interesting planes and study their features. It is Yak-36 which is a very interesting device, since it was the first aircraft created in the USSR, which could produce vertical take-off and landing. Before that, no OKB could boast of such machines. Due to the huge amount of work done, the designers managed to achieve high results and gain experience in the creation of such machines, which was actively used by other design bureaus later. It should be noted that the designers of Yakovlev almost always differed in creativity and brought their projects to the end or until the time allowed for the government.
