Yak-200 and Yak-210, A.S.Yakovlev

In late 40's introduction of jet-bomber Il-28 specialized trainer aircraft became a necessity. A.S.Yakovlev OKB was charged with the project. Aircraft had to be much cheaper than the jet bomber, but have same cockpits layout and instrumentation, similar handling, performance (low-speed, of course) and even appearance.

Two variants of trainer were built - for pilots (Yak-200) and bombers/navigators (Yak-210) practice. Yak-200 had side-by-side seated pilot and instructor, while Yak-210 had side-by-side arrangement for instructor in glazed nose. Yak-210 also carried a bomb-aiming radar PSBN-M, installed in the radio-transparent fairing under the fuselage right aft the wing and AFA-BA-40 photocamera. It could carry 6 bombs on underwing hardpoints.

Both variants were equipped for all-weather operations: radio stations RSIU-3, RSB-5, radiocompass ARK-5, radio-altimeters RV-2 (low altitude) and RV-10 (high altitude), friend/foe ID system, marker receiver and intercom.

Yak-200 and Yak-210 carried some similarities to Yak-16 (wing and tail units) had identical all-metal construction with fabric skin on tail controls, ailerons and (partially) flaps. Pneumatic system was used to operate landing gear, wheel brakes and flaps. Engines were installed in underwing nacells, practically identical to nose section of the Yak-11 trainer. Oil coolers were installed inside the wing, as well as fuel tanks.

Trials started in 1953: Yak-200 in March, Yak-210 in July. Yak-210 was heavier, but performance of both was practically identical and in perfect agreement with requirements. Flight tests revealed serious handling and stability problems. Yak-200 was found statically unstable on some flight regimes. In case of one engine failure, aircraft had a trend to slide with serious risk of spin.

It was obvious that there is no quick cure by introducing of minor changes. Taking into account that trainer version of the Il-28 entered production, development of Yak-200/210 was cancelled.
