Raduga Kh-28 (AS-9 Kyle)

Tactical missiles were also built by A. Berezhnyak's "Raduga" OKB engineering group, but by a different route than taken by the "Zvezda" Design Bureau. While "Zvezda" started from light air-to-air missiles, "Raduga" scaled down heavy air-to-ground missiles for strategic aircraft into light tactical ones.

The Kh-28 (Article 93, alias D8) was built by applying to it Kh-22 and KSR-5 features. Its structure is a conventional aerodynamic one, with small delta wings. Its propulsion system is a two-stage liquid-fuel rocket engine. It was produced as early as the nineteen sixties, especially as an antiradar missile for Yak-28 bomber aircraft (the first Soviet missile of this type). It was, however, never actually put on Yak-28 aircraft but instead used as weapon of Su-7B/17/24 and Tu-22M aircraft. Series production of the Kh-28 began in 1971. The warhead is programmed prior to the missile launch, either by a "Filin" [Eagle Owl] set on board the aircraft (Su-24) or a "Metel" [Blizzard] set suspended from the aircraft (Su-7B/17, Tu-22M), to track the frequency of detected enemy ground radar. On the Su-17 aircraft this missile is suspended under the center line of the fuselage and the "Metel" set on the right underwing pylon. The missile is no longer used.

X -28 - aircraft antiradar cruise missile of class?vozdux- surface? for the front aviation. Guidance system - PRLGSN. Engine - ZHRD - LIQUID PROPELLANT ROCKET ENGINE (R2shche-e00). Glider in appearance is such to rocket airframe X -22M, but it is characterized by overall sizes and absence of lower crest. Front fairing with the cargo hold has xomutno- wedge quick-disconnect fitting. Basic materials: AMG-' (skin), E0KHGSA (load-bearing elements), D -19.

In 1964 the mastery of the fiberglass laminate fairings about the rocket X, began. They although small according to the sizes (1250 mm X of 300 mm), requirement for the characteristics of radiotransparency were so rigid which for the first series of articles was necessary to complete three fairings, calculated each for its wave band. This required heavy expenses for each article. How in our aircraft industry, so also in a number of foreign aviafirm, there were the searches for the methods of preparing?svetlykh? (in the radio-technical sense) fairings. Carried out searches for?prosvetleniya? fairings they ended by the selection of the so-called?kompensatsionnykh lattices?, with the aid of which attained a substantial improvement in the radio-technical characteristics of the fairings about the rocket X -28, and then the rockets X -22. The blocks of the apportionment of aggregates with the application pneumo- and of hydraulic cylinders entered into the composition of articles X -22 and X -28. A question of finish machining of packing surfaces was problematic. As a result of introducing the process of diamond smoothing it was possible to forego the labor-consuming operations of the abrasive finishing of these surfaces, having simultaneously increased the quality of their working. Leading of this direction were the colleagues OF NIAT A. m. churayev and V. i. gasilin.
