The Jakowlew Jak-30 ( Russian Яковлев Як-30 , NATO code name Magnum ) is a Soviet jet trainer for training jet pilots from the Experimental Design Office (OKB) Jakowlew from 1960.
history
This pattern was created on the basis of a tender for a standard jet trainer for the Warsaw Pact air force as a competitor to the Polish TS-11 Iskra and the Czechoslovak L-29 Delfin . The order was placed on July 31, 1958 and development began as Jak-104 in the late 1950s. The construction of the OKB was based on the series of light, single-engined fighter planes it developed in the 1940s, some of which were taken over from components such as wings and landing gear. The horizontal stabilizer of the Jak-23 served as a model as well as the vertical stabilizer of the Jäger from 1948, also named Jak-30 . The hull, however, was a completely new design.
The first flight took place on May 20, 1960 with the pilot Vladimir Smirnov. Together with a second prototype ( yellow 50 ), which was completed a little later , the 82 flights and 43 flight hours of extensive factory testing were completed and completed in March 1961. At the same time, the state acceptance flights took place, which were carried out by two other aircraft ( yellow 80 and yellow 90 ) from August 1960 and successfully completed on August 14, 1961. In the subsequent comparison flights in Monino in September 1961 with the two competitive models, the Jak-30 performed very well. However, since the maintenance of the machine was too time-consuming and complicated, the decision was ultimately made in favor of the L-29, which was then also built in large numbers over the next few years.
Nonetheless, the Jak-30 was tested further. On September 22nd, 1961 Vladimir Smirnov was able to fly with the type 767.3 km / h over a 15- / 25-km distance and thus a world record for this class, on September 25th a record height of 16,128 m was reached. In November 1961, the third prototype was examined for use as a ground attack aircraft. In addition, the yellow 80 received two lower wing stations, where either containers for unguided air-to-ground missiles or 100 kg free-fall bombs could be carried. Two prototypes were converted into control aircraft in the spring of 1962. For a number of years they served as Jak-30KP and Jak-30M for the remote control of Jak-25RW-II altitude reconnaissance aircraft that had been converted to unmanned drones .
A single-seat development appeared in 1961 under the name Jak-32 .
The designation Jakowlew Jak-30 also carries a front fighter from 1948, see Jakowlew Jak-30 (1948) .
