Tumansky R-15 : ウィキペディア英語版 | Tumansky R-15
The Tumansky R-15 is an axial flow, single shaft turbojet with an afterburner. Its best known use is on the Mikoyan-Gurevich MiG-25. ==Design and development== The R-15-300 was designed at OKB-300 design bureau led by Sergei Tumansky in the late 1950s. The engine was originally designed to be used in the Tupolev Tu-121 high-altitude high-speed cruise missile. Due to lacking Soviet resources and funding the engine casing was mainly steel, and in areas exposed to high levels of heat, 30 micrometre silver-plated steel. At the time, the USSR did not have the resources to exploit metals such as titanium, or other composite alloys, which could have greatly reduced the engine's weight. The Tu-121 effort was later canceled, but its basic design was re-used to create the Tupolev Tu-123 reconnaissance drone.
