Wright R-3350 Cyclone 18

Specifications |

The R-3350 was one of the most powerful radial engines produced in the
United States. Using 18 cylinders of the R-2600, gave it a
displacement of 3,342 cubic inches. The crucial application
was for the Boeing B-29.
The R-3350 was first run in 1937. The earliest
flight I can find is on the XB-19 in 1941. The Cyclone 18
became the engine of choice for large military and civilian aircraft
into the 1950s.
Some later versions of the R-3350 were produced as
"turbo compound" engines. Three exhaust driven
turbines converted about 20% of the exhaust gas heat energy into
useful power. These turbines drove a gearing mechanism that
added power to the engine crankshaft.
