Ilyushin Il-30

From PlaneSpottingWorld, for aviation fans everywhere

The Ilyushin Il-30 was a Soviet turbojet-powered tactical bomber designed as a higher-performance version of the Il-28 in the late 1940s. It was apparently canceled before the prototype made its first flight, although sources disagree on this.


The Il-30 was a follow-on to the Il-28, although design began on 21 June 1948, before the Il-28 had flown. It was designed to meet a requirement for a jet bomber that could carry Template:Convert to a range of Template:Convert with a maximum speed no less than Template:Convert. The design took that of the Il-28 as a starting point, but had thin, mid-mounted swept wings with a 35° sweep angle chosen to allow the aircraft to reach its required speed. It was intended to be powered by two new Lyul'ka TR-3 axial-flow turbojet engines with 45.1 kN (10,140 lbf) thrust each in wing-mounted nacelles. Both the fuselage and nacelles were area ruled.[1]

The thin wing and the 2° anhedral necessary to cure the excessive lateral stability meant limited the amount of fuel that could be carried and tip tanks were required to meet the range requirement. The slim engine nacelles did not allow the main landing gear to be stowed there as was done in the Il-28. The solution was to house them within the fuselage — the first bicycle landing gear on a Soviet aircraft — with small, twin-wheeled, outriggers mounted underneath the nacelles to stabilize the aircraft on the ground.[2] The aircraft had a crew of four, the pilot, a bombardier, and two gunners. The pilot, bombardier and the dorsal gunner shared one pressurized compartment that was subdivided into the cockpit and the bombardier's position in the extensively glazed nose. The dorsal gunner was placed back-to-back with the pilot underneath the canopy and the tail gunner had his own separate pressurized compartment at the rear of the aircraft. Defensive armament was six Template:Convert Nudelman-Rikhter NR-23 cannon, two fixed forward and one pair each in the Il-V-12 dorsal turret immediately behind the cockpit and the Il-K6 tail turret. Maximum bomb load was Template:Convert[2]

The initial results were favorable, and a full-scale mockup was formally reviewed in March 1949. The prototype was completed by August 1949, but an incident involving the rival swept-wing Tupolev Tu-82 led to delays as additional tests were demanded to determine the strength of the wings before the first flight was made. By the following year, the Il-30 program had lost momentum as the Ilyushin OKB was ordered to concentrate on facilitating the service introduction of the Il-28. It was formally terminated by government order on 20 August 1950, and the prototype was eventually scrapped at the beginning of the 1960s.[3]

Although the Il-30 never actually flew[3], it was the subject of much (misinformed) speculation in the West. Some of the common misconceptions were that it had a ventral gun mount and that it was the first Soviet bomber to attain the speed of Template:Convert.[3]
