Yakovlev Yak-30

 

In the Yakovlev Design Bureau in 1957, in accordance with the government decree, the creation of a two-seat Yak-104 aircraft began. At the very beginning, it was planned for the engine R-5-45 NG. Metskhverishvili, but in due course in connection with the termination of development on the engine all works on it have been frozen. 31 July 1958 year was a new decree on the creation of the Yak-104 aircraft, but with the engine designs of S.K. TUMAN RU19-300. The Yak-104, which later received the designation Yak-30, is an all-metal low-wing with a single-tailed tail and a trapezoidal wing with an average stabilizer location.

Yak-30 (Magnum) - Soviet jet training aircraft. In 1960, he made the first flight. A year later, he managed to win the competition for training jet machines for the Soviet Air Force in PZL TS-11 Iskra (Poland) and Aero L-29 Delfin (Czechoslovakia). However, serial production reached L-29 Delfin, since it is expected to build on the Czechoslovakian aviation enterprises that are more adapted. Double-metal aircraft has high maneuverability and a very contemporary design for those years, was created only four copies.

Yakovlev in 1957 year began to design a training jet machine, which received the designation Yak-104.

Three years later, were created 2 experienced Yak-104 (board «30» and board «50» 15 21 May and July, respectively). KV Sinel'shchikov has been a leading designer and acting deputy designer general AS Yakovlev. A plane was renamed to the Yak-30.

In the period from May 20 1960 1961 to March, both machines are factory tested. They consisted of 82 flight duration - hours 43 36 minutes. In operation of the engine and the aircraft had no difficulty. 1500 speed km / h was reached at the height of 788 m. For all programs airliner received positive evaluation.

The reclining gasroot is installed in the upper part of the fuselage, inside of which the electric cables are connected to the control rod. In front of the fuselage there is a ventilation box and ventilation equipment units with ejection seats with a curtain. To improve the review of the instructor, the rear seat is slightly higher than the front. For the first time in our country, the bailout could be done through glazing, without the need to reset the flashlight, when pulling out a soft curtain that provides face protection. This method allows you to significantly reduce the time of leaving the aircraft in the event of an accident. Three-wheeled chassis with a bow support. In the middle of the fuselage, there is an engine. Air intake has 2 output in the root parts of the wing, which are protected from penetration of foreign objects by reliable grids with side windows. The installation of doors is similar to the old scheme of old jet fighters.

On May 29 1960 1961 to March, the tests were carried out on the two factory cars. July 2 1960, the first aircraft made a flight, it was piloted VG Mukhin. L-2 «Dolphin» (Czechoslovakia) and TS-29 «Iskra» (Poland): Almost in parallel with this 11 sport aircraft have been created. In 1961 year airfield near Moscow passed comparative flight tests of these models and our Yak-30. Despite all the expert advice taken Yak-30, the judges gave the Czechoslovak L-29 «Dolphin".

State tests of the Yak-30 began in late August 1960 years. The machine demonstrated the full range of aerobatics. Successfully tested bailout, which provided safe leaving the aircraft through the glazing. In September 1961, after state tests, pilot VP Smirnov second Yak-30 2 was set world records: height - 16 128 m, speed - 767,308 km / h based on 15-25 km.

In 1959, the government issued a decree on the establishment of the Yak-30 single aircraft model. There were built Yak-3 32. Since January 1961 the aircraft was tested, and the state is not carried out. Test pilots were able to establish the Yak-32 three world records speed and altitude.

Yak-30 (1948)

The Yak-30 became the first jet machine, which was manufactured in the Yakovlev Design Bureau in the late 40-ies, with the arrow shaped wing. There were created two machines of this type. Commercially not manufactured.

History of the Yak-30

The basis of the new aircraft project Yak-25 was taken, but these devices have one significant difference, namely the form of the wing. The wings on the new machine have arrow-shaped. Sweep was 35 °. The wing is made of a single member. The wing structure have been incorporated aerodynamic ridges. Most other systems have been used with previous machines.

The first flight was carried out in early September 1948 years, after which followed the production tests, which were completed by December 48 years. The test results were marked by ease of management and control access to the pilots of the middle class. When compared to the original machine, the Yak-30 had many benefits in flight performance. It was obtained due to a new wing structure.

Yak-30

At the end of 48, the second Yak-30D aircraft was manufactured. It was distinguished by a more perfect wing, which consisted of two spars. Also, the fuel and combat power were increased. The wings already had retractable flaps. The tail part of the apparatus was equipped with brake flaps. State tests were started in 49 year and passed on the Crimean peninsula. During the tests, the number M was obtained, which was equal to 0,93. Tests by the state commission were completed at the end of May 49. Despite the successes in the tests, this machine was never put into serial production due to the fact that there were similar aircraft of the MiG-15 and La-15 type.

Design features of the Yak-30

The fuselage of the aircraft in its design almost completely corresponded to the aircraft Yak-25. The body consists of two sections, between which is the service connector for servicing the engine. The power plant of the machine occupied the tail part of the hull. The cockpit was located in the middle of the vehicle, two air intakes were placed on its sides. The wings had a high degree of sweep, which gave the aircraft much better flight and maneuverability characteristics. On the wings were mounted mounts for suspension fuel tanks with a total capacity of 380 liters. In the main tanks of the aircraft it was possible to fill 3,3 tons of fuel.

Yak-30

The cockpit is made on a sealed circuit with a ventilation system. To protect the pilot's cabin has a greater degree of reservation by metal plates, windshield and armored and has a thickness in 5,7 cm. The back of the chair is made of 8-millimeter armor. For the evacuation of the pilot in an emergency ejection seat equipped with the system.

By the combat power of the aircraft are two large-caliber gun W-3-23 150s charge to patrons, but they were soon replaced by the HP-23. Armament was located under the cockpit. The composition of airborne equipment was included finder type RPKO-10 and a radio RCI-6. The Yak-30 was set fotokinopulemet C-13. All systems are fed with electricity from the generator and 12-volt battery.

Constantly continuing to search for the most effective scheme of light fighter Yakovlev team in 1948 he was transferred to the test Yak 30 with engines of Rolls Royce * *.
UC 30 was built on the basis of 29 Yak and Yak is a deep modification 25.
Externally, 30 and 29 Yaks differed slightly, but in terms of their performance characteristics, the Yak 30 was significantly more attractive and it was he who went into mass production, leaving the Yak 29 project on paper. The plane was quite simple in control, perfectly performed all the aerobatics figures. Later the machine was built Yak 30D (doubler) with increased fuel and ammunition. Flight characteristics of the modified car, although they became a little lower, but remained quite high. Tests Yak 30D completed in 1949 year, but by that time MiG-15 and La-15 were already mass-produced, so there was not a place in the Air Force system for the Yak 30.

I am an active observer and a fan of aviation sports, so I can say that great quality Yak-30. It is this jet kid was able to show all the possibilities of flying machines on Yakovlev. In addition the device has an improved Yak-32 was established on the basis of the ego. As for the original model, namely the Yak-30 something about it can be said that he had once set world records aerobatics.
