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. Stills from this animation set can be viewed HERE.
The definitive book on the R-2800 is available from the Society of Automotive Engineers.
