The J47 is an American turbojet engine developed by General Electric from its earlier J35 engine in the early Cold War. It was the first axial-flow turbojet approved for commercial service in the United States. This engine powered some of the most iconic aircraft of the post-war era, such as the F-86 Sabre, the B-47 Stratojet, and the Convair B-36 Peacemaker. It had a single-spool compressor, a reverse-flow combustor, and a double-spool turbine. The J47 could produce up to 6,000 lbf (27 kN) of thrust, depending on the model and configuration.
