Скачать или смотреть Yakovlev Yak-28 - A beautiful Swept-Wing Design As a Symbol of the Supersonic Era

Yakolev's approach to the Yak-28 was a no-frills design, similar to the other Soviet turbojet-powered aircraft of the time. The Yak-28 had a conventional aerodynamic design, it was a cantilevered, high-mounted, swept-shaped wing and a four-bearing bicycle-type chassis. Glider aircraft made entirely of aluminum alloys.
Yak-28 had a length of 21.6 meters (70 ft 10 in), a wingspan of 12.5 meters (41 ft 0 in), a height of 3.95 meters (13 ft 0 in), an empty weight of 9.97 tons, and a maximum takeoff weight of 20 tons.
