General Electric YJ93

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. [ [http://home.att.net/~jbaugher2/b58_9.html NB-58A Testbed for General Electric J93 ] ]
