The Yakovlev in 1957, in accordance with the government decree began the creation of double Yak-104. In the beginning it was planned under the engine F-5-45 NG Metshverishvili, but eventually in connection with the termination of the development of the engine for all the work they had been frozen on it. July 31 1958, it was a new decree on the establishment of the Yak-104, but SK with engine design Tumansky RU19-300. The Yak-104, who later received the designation Yak-30, is an all-metal nizkoplan odnokilevym with feathers and tapered wing with the average location of the stabilizer.
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.
Fold-fairing mounted on top of the fuselage, in which laid electroplaits to the control rod. In front of the fuselage is germokorobka type of ventilation and ventilation equipment units such as ejection seats with curtain. rear seat slightly higher than the front to improve the instructor review. For the first time in our country a bailout could be carried out through the windows, without having to reset the lamp, when vydviganii soft curtain, providing face protection. Such a method can significantly reduce the time of leaving the aircraft in case of an accident. Tricycle landing gear with a nose wheel. In the middle part of the fuselage-mounted engine. The air intake has 2 output in the wing roots, which are protected against the ingress of foreign objects with robust mesh side windows. Installation of doors similar to the old scheme Reda 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.
Yakovlev Yak-30 characteristics:
|Aircraft Length m||10.14|
|Wing area, m2||14.30|
|engine's type||1 TRD RU-19-300|
|Thrust, kgf||X 1 900|
|Maximum speed km / h||660|
|Cruising speed, km / h||548|
|Practical range, km||500|
|Practical ceiling, m||14000|
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.
At the end of the year 48 was made the second Yak-30D. He had a more perfect wing, which consisted of two spars. There was also increased fuel capacity and combat power. Wings had already retractable flaps. The tail part of the apparatus equipped with the brake flaps. State tests were started in 49 year and held in the Crimean peninsula. When testing a number M, which is equal to 0,93 was obtained. Testing by the state commission were completed in late May 49 years. Despite advances in testing, this machine has not been put into serial production due to the fact that there were similar aircraft such as the MiG-15 and 15-La.
Design features of the Yak-30
The fuselage of the aircraft in its construction almost matched the plane Yak-25. The housing consists of two sections, between which there is a connector for operating the engine maintenance. Power plant machinery took the tail part of the body. Cockpit was located in the middle of the unit laterally from it two inlet were placed. The wings have a high degree of sweep, which gave much better aircraft flying and maneuvering characteristics. On the wings were installed for mounting external fuel tanks with a total capacity in liters 380. The main aircraft tanks could fill 3,3 tons of fuel.
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.
