They mean turbojets ("conventional" jet engines). The SR-71 doesn't use a conventional jet engine. http://en.wikipedia.org/wiki/Lockheed_SR-71_Blackbird#Engine... >A unique hybrid, the engine can be thought of as a turbojet inside a ramjet. At lower speeds, the turbojet provided most of the compression and most of the energy from fuel combustion. At higher speeds, the turbojet largely ceased to provide thrust; instead, air was compressed by the shock cones and fuel burned in the afterburner. |
