Wright Cyclone R-3350-TC Cylinder
The major airframe application of the Wright R-3350 engine was the Boeing B-29 during World War II. This engine continued to give useful commercial service after the War, one version of which was the first of its type to have its exhaust turbines (3 of them) geared into the power system. This engine, called the Wright Turbo-Compound Cyclone, was the last and the most highly developed piston engine to be widely used in large military and commercial airplanes. It was used in commercial aircraft such as the Douglas DC-7 and Lockheed Super Constellation.
