Pratt & Whitney R-2800<
|The Pratt & Whitney R-2800 "Double Wasp" was probably the most important aircraft piston engine ever produced. It powered more different types of aircraft than any other. In addition to its inestimable contribution to victory in World War II, it also helped establish postwar commercial aviation in classic prop liners such as the Martin 404 and Douglas DC-6.|
|Ralph Jones has created a beautiful series of R-2800 component animations.
