Yakolev Yak-30 [1948]

yak-30-48


The Yakolev OKB's response to the March 1946 requirement for a Rolls-Royce Derwent-powered Mach=0.9 "frontal" or general-purpose tactical fighter suitable for use from existing unpaved airfields was the Yak-30. Derived from the Yak-25 from which it differed primarily in having wings sweptback 35 degrees at quarter chord, the Yak-30 retained the fuselage, tail surfaces and undercarriage of the earlier fighter fundamentally unchanged, together with the three-NR-23 cannon armament. Powered by a 1590kg RD-500 turbojet, the first of two Yak-30 prototypes was flown on 4 September 1948. The second prototype, the Yak-30D, which joined the flight test programme early in 1949, had a 38cm section inserted in the aft fuselage, revised mainwheel doors forming a large section of the fuselage skinning, Fowler-type flaps in place of split flaps, increased fuel and ammunition capacity, and changes to the oxygen system and radio equipment. The Yak-30D was also fitted with air brakes on the aft fuselage. Normal loaded weight (without external fuel) was increased by 110kg. Although the modifications introduced by the Yak-30D eradicated several shortcomings displayed by the first prototype, the first production deliveries of the superior MiG-15 were already taking place by the time that the improved version of the Yakolev fighter entered flight test, and the results of NIl V-VS trials were, therefore, little more than academic.
