Wright Aeronautical R-3350-23 Cyclone 18


The Wright R-3350 was one of the most powerful radial engines produced by the United States and was based earlier Cyclone engines and was chosen as the powerplant for the Boeing B-29.

Work on the engine began in January, 1936 and was first was tested in May, 1937. It was similar in design to the company's R-2500 14-cylinder radial. It shared the same bore and stroke but added two more cylinders per row for additional displacement. A three-piece forged alumium (later changed to steel) crankcase, cast heads and a magnesium supercharger case reduced weight.

Approximately 33,000 engines were built by Wright Aeronautical and Chrysler's Dodge Division. More R-335023/23A engines were built than any other R-3350 model.

This engine is located in the B-29 Hangar.
