- General Electric YJ93
The General Electric YJ93
turbojet engine was designed as the powerplant for both the North AmericanXB-70A Valkyrie bomber and the North AmericanXF-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.
