Someone is selling a contractors model of an engine for a cruise missile on ebay. The engine is an unducted aft fan design. This type of engine was proposed for use on jetliners; it provides fuel efficiency benefits but in the end the brain-melting noise it put out doomed the concept. Not only did it bother people, it also tended to buzz the bejeebers out of the aircraft structure. In the end very high bypass conventional turbofan engines proved capable of doing the job. Noise, of course, would not have been much of an issue for a cruise missile, but since this design was put forward (circa 1989) the US has not fielded any new major cruise missiles.

Note:”TCAE /GEAE” likely stands for Teledyne Continental Aviation and Engineering / General Electric Aviation Engines. Teledyne CAE was known as such between 1969 and 1999, an unhelpful 30-year span.
