Pratt & Whitney R-1830 Twin Wasp

The Engine  Specifications
 

In 1927, Pratt & Whitney began researching twin-row radial engines.  One result, the R-1830 Twin Wasp, first flew in 1931.  It was one of the most efficient and reliable engines of the 1930s.

The R-1830 was in production from 1931 through 1951.  Over 173,000 were produced, more than any other aircraft engine (per Pratt & Whitney).
