RD-9 Preserved Tumansky RD-9B turbojet engine Type Turbojet Manufacturer Tumansky First run 1953 Major applications Yak-25
MiG-19The Tumansky RD-9 was the first Soviet turbojet engine not based on pre-existing German or British designs. It was a development of the Mikulin AM-5, featuring a new compressor with higher subsonic airflow. The engine completed testing in 1953 and produced 5,732 lbf (25.50 kN) thrust without afterburner. When Sergei Tumansky replaced Alexander Mikulin as the OKB-24's chief designer in 1956, the engine was renamed RD-9. The engine was built under license in China as the WP-6.
