Yakovlev Yak-28 - Design and Development

Design and Development

It was first seen by the West at the Tushino air show in 1961. Western analysts initially believed it to be a fighter rather than an attack aircraft — and a continuation of the Yak-25M, at that — and it was designated "Flashlight". After its actual role was realized, the Yak-28 bomber series was redesignated "Brewer".

The Yak-28 had a large mid-mounted wing, swept at 45 degrees. The tailplane set halfway up the vertical fin (with cut-outs to allow rudder movement). Slats were fitted on the leading edges and slotted flaps are mounted on the trailing edges of the wings. The two Tumansky R-11 turbojet engines, initially with 57 kN (12,795 lbf) thrust each, were mounted in pods, similar to the previous Yak-25. The wing-mounted engines and bicycle-type main landing gear (supplemented by outrigger wheels in fairings near the wingtips) were widely spaced, allowing most of the fuselage to be used for fuel and equipment. It was primarily subsonic, although Mach 1 could be exceeded at high altitude.

Total production of all Yak-28s was 1,180.

Famous quotes containing the words design and/or development:

    Westerners inherit
    A design for living
    Deeper into matter—
    Not without due patter
    Of a great misgiving.
    Robert Frost (1874–1963)

    Women, because of their colonial relationship to men, have to fight for their own independence. This fight for our own independence will lead to the growth and development of the revolutionary movement in this country. Only the independent woman can be truly effective in the larger revolutionary struggle.
