General Electric YJ93
From Wikipedia, the free encyclopedia
The General Electric YJ93 turbojet engine was designed as the powerplant for both the North American XB-70A Valkyrie bomber and the North American XF-108 Rapier interceptor. The YJ93 was a single-shaft axial-flow turbojet with a variable-stator compressor and a fully-variable convergent/divergent exhaust nozzle. The maximum sea-level thrust was 31,500 pounds.
Unfortunately, the XF-108 interceptor was cancelled outright and the B-70 project was reoriented to a research project only.[1]
