Allison J35
Encyclopedia : A : AL : ALL : Allison J35
The Allison J35 was originally developed by the General Electric Company in parallel with the Whittle-based centrifugal-flow J33, and was the Air Force's first axial-flow (straight-through airflow) compressor engine. The J35 was fairly simple, consisting of an eleven-stage axial-flow compressor and a single-stage turbine. With the afterburner, which most models carried, it produced 7,400 lbf.
Operational History
The J35 first flew in the XP-84 in 1946. Late in 1947, complete responsibility for the production of the engine was transferred to the Allison Division of General Motors. More than 14,000 J35s had been built by the time production ended in 1955.The J35 was used to power the X-5 variable-sweep research aircraft and various prototypes such as the XB-43, XB-45, XB-46, XB-47, XB-48, and XB-49. It is probably best known, however, as the engine used in two of the Air Force's leading fighters of the 1950s, the F-84B/C/D/E/G "Thunderjet" and the F-89 "Scorpion."
