General Electric J47

The Engine Specifications (J47-A)
 
After losing the J33 and J35 to rival Allison, GE decided to design a J35 replacement.  Using the same frame size as the J35, the J47 used a new compressor and turbine.  First flight tested in 1948, the J47 was also the first axial-flow engine in the United States to be approved for commercial use.

By the time production ended in 1956 36,500 had been built requiring production at Studebaker and Packard.
