Through a representative in England, General Electric learned of the pioneering jet engine development of Frank Whittle. This resulted in a visit by General H.H. Arnold, Chief of the U.S. Army Air Corps, and manufacture of the Whittle engine by GE. The American engine incorporated a number of mechanical improvements, and two I-A engines first flew in a Bell P-59A in 1942.
GE followed with two designs of increased thrust; first the I-14 (aimed at 6,227 N (1,400 lb.) thrust) and then with the I-16. The J31-GE-4 or -5 (I-16-4 or-5) models provided continuing improvements such as improved turbine cooling intended for the P-59 aircraft.
Believing future tactical needs would require turbojets to use the same fuel as reciprocating engines, the U.S. Navy developed a 100-octane, gasoline-burning version of the standard I-16, which normally ran on kerosene fuel. The Navy’s first application of jet propulsion was the Ryan FR Fireball, a mixed-power (piston and jet-powered) fighter aircraft.
