MiG 211 / 2111 / Analog

The airframe of the test bed was that of a MiG-21S fitted with a compound sweepback delta wing (78 degrees at the wing root over one – third of the leading edge, then 55 degrees) Its thickness-chord ratio tapered from 2 3 percent at the wing root to 2 5 percent at the wing tip The trailing edge was shared evenly by the flaps and elevons The plan view of the wing was almost identical to that of the Tu-144—hence the nickname “Analog"

Two MiG-21Is were needed for research purposes No. 1 was first piloted by О V. Gudkov on 18 April 1968, and the flight tests continued for about one year Unfortunately, just after completion of the basic tests the prototype was destroyed. No 2 was kept airworthy for several years. Both MiG-21Is were powered by the R-13F-300 capable of 6,360 daN (6,490 kg st) The total capacity of the fuel tanks was 3,270 1 (864 US gallons). Both aircraft were used to train the first two pilots of the Tu-144, E Yelyan and M Kozlov
