The Tumansky RD-9 (initially designated Mikulin AM-5) was an early Soviet turbojet engine, not based on pre-existing German or British designs. The AM-5 was available in 1952 and completed testing in 1953; it produced thrust without afterburner. AM-5 engine is notable for making possible the first Soviet supersonic interceptor, the MiG-19 and the first all-weather area interceptor, the Yak-25. When Sergei Tumansky replaced Alexander Mikulin as the OKB-24's chief designer in 1956, the engine was renamed RD-9. The engine was later built under license in China as the WP-6. ==Variants and applications== ;RD-9A: ;RD-9B: Used in the East German civilian jetliner project Baade 152 in 1958 and 1959, replaced when Pirna 014 engines became available. ;RD-9AK: Non-afterburning versions for the Yak-25 and Yak-26. ;RD-9AF-300: Afterburning version for the Yak-27 and Yak-28. ;RD-9AF2-300: Afterburning version for the Yak-27 and Yak-28. ;RD-9B: Afterburning version for early MiG-19s. ;RD-9BF-811: Afterburning version for later MiG-19s. ;RD-9V: Afterburning version used in the Ilyushin Il-40P. ;WP-6: Chinese built version for the Shenyang J-6. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Tumansky RD-9」の詳細全文を読む スポンサード リンク
