General Electric J47 Turbojet Cut-Away

The General Electric J47 turbojet (GE company designation TG-190) was developed by General Electric from its earlier J35 engine. It first flew in May 1948. The J47 was the first axial-flow turbojet approved for commercial use in the United States. The engine was produced in at least 17 different series and was used to power such USAF aircraft as the F-86, FJ-2, XF-91, B-36, B-45, B-47, KB-50J, KC-97L and XB-51 and more than 36,000 were manufactured before production ended in 1956. Packard built 3,025 of the engines under license.

The J47 was advertised as an “all-weather engine” due to its anti-icing systems which allowed it to perform at high altitudes and extreme temperatures.

The J47 was retired from active military duty when the last Boeing KC-97L was withdrawn from the Air National Guard service in 1978, thus spanning 30 years of operational service.

Part of the engine casing has been cut away to reveal the engine’s internal components.
