GE J31 Turbojet Engine, Cutaway, Motorized

General Electric J31

Early flight tests of the first General Electric turbojet engine, the Type I-A, clearly showed the need for more powerful engines. GE followed with designs generating increased thrust, including the I-16, designated J31 by the military, which first ran in April 1943. About 250 were built, mainly for variants of the Bell P-59 Airacomet.

GE developed this engine for the U.S. Navy as a 100-octane, gasoline-burning version of the standard J31 engine, which normally ran on kerosene fuel.

Development began in 1943, when the government believed that future tactical needs would require turbojet engines to use the same fuel as reciprocating engines. Before it was made into a cutaway, this engine, along with a Wright R-1820 piston engine, powered the Ryan FR-1, the Navy’s first partially jet-powered aircraft.
