Tumansky M-88
The Tumansky M-88 was an air-cooled radial engine for aircraft developed in the Soviet Union shortly before World War II.

Design and Development:
The M-88 was designed to address the shortcomings of the Tumansky M-87. The improvements incorporated in the M-88 were a strengthened crankcase, crankshaft, connecting rods, waffle ribbing at the piston bottom and a two speed geared centrifugal supercharger. The M-88 retained the same bore/stroke and displacement as the M-87 while increasing power to 1,000 - 1,150 hp. Design work began in 1937 and by 1939 the first prototypes were being flight tested in the Polikarpov I-180 fighter prototypes. At first the M-88 was not a success, but the designers persisted and the M-88 was made into a reliable and widely produced engine. There were a number of different variants with the most numerous being the M-88B, of which 10,585 were produced at Zaporozhye and Omsk. The M-88B solved most of the mechanical failures associated with the M-87 and early M-88's by including oil injectors in the crankshaft, improved cooling and strengthened drive components. 16,087 M-88's were produced.

  • Ilyushin Il-4
