The R-3350 Cyclone was designed in the US by the Wright Company. The Cyclone engine was first tested in May, 1937 and versions of the engine remained in production well into 1950’s.
The R-3350 found use in both civilian and military applications. It powered such aircraft as the Boeing B-29 Superfortress, Canadair CP-107 Argus, Fairchild C-119 Flying Boxcar, Douglas A-1 Skyraider and the Lockheed Constellation.
This version of the R-3350 is the R-3350-TC-EA 1 Turbo Compound. It was used on the Canadair Argus, a maritime patrol aircraft. It took four of these engines to power the Argus and they were capable of producing enormous amounts of heat and electrical power. In fact one aircraft could generate enough electricity to service 26 houses in the cold depths of the winter.
ACAM acquired a cutaway 3350 in 2002. This engine has been cleaned up and restored. It now has a small motor attached to the starter motor allowing the engine to be turned over by a visitor so that all the parts can be seen moving. Last touches on this engine should be completed in 2008 and glass will be installed in the exhibit cabinet. Once completed, the engine in the top picture minus the engine cowl will become surplus and will be removed from exhibit.
