Hello everyone, first time post here. I've got a mystery engine on my hands, I figure this may be a fun challenge for you guys to help me solve My lab just acquired an old engine that was being thrown out. My boss decided to give it a home in our high-bay and we want to cross-section it for display. The problem is, we have no idea what it actually is. The engine never flew but it did run. It has a bit of damage in the turbine which manifests itself as a quite grinding when you spin the shaft. The external plumbing is mostly missing, but the internals are all intact.  Here is the engine overall, the inlet is about a foot across.   Here is the ONLY bit of information on the case. It was built in 1988 but we're not sure by who. I've searched a bunch of combinations for the model and serial number but have yet to find anything promising. We are guessing it was meant for some sort of UAV. But thats about all we know. I'll continue my search and let you guys know if I figure it out! |

Nice engine! Crying shame it's going to be sectioned, but as it look like a disposable engine (likely cruise missile) that's probably better than it could hope for if it has core damage  My first thought was a Teledyne engine due to the case but the intake spike put paid to that. Need to fire up the GIS! Edit: Looks verrry similar to a Microturbo TRI-40. Wonder if it's a variant... |

Need to fire up the GIS! Yea it won't run. As I said with the damage and missing equipment, sectioning it for use as an educational tool is really the only thing we can do with it rather than leave it sit and collect dust. I've been looking into old-school UAV's and cruise-missiles all morning with no luck  |

Is it a fan engine ??
How many compressor stages ??
Whats the rear end look like ??
Williams maybe ??
Cheers

Looks a lot like an engine out of a SOM. There are some differences, but a lot of similarities. Could you find out the overall length, inlet diameter, or any technical specs?  EDIT: Did some more looking, it looks very similar to the chineese 700kgf engine used in UAV's and cruise missiles, but the english printed on the labels wouldnt suggest this to be the case. I agree that it fits the profile of an engine that belongs in either a UAV or cruise missile.  |

I'm not sure about the compressor stages, my supervisor won't let us open it until we are certain what it is. I have been leaning towards Williams, but I can't determine which model it might be. |

The inlet diameter is 12" and the length is roughly 3 feet. It doesn't run and I have no documentation so technical specs are kind of out of the question. That first picture really looks similar though. The way the lip around the inlet is formed and the angle and size of the fan are the most promising bits. The only problem is I believe that image is of a new Turkish prototype, but this engine is from 1988 and I believe they are no longer built. |

plz don't cut it. Repurpose it, we'll help! With all due respect I don't think you guys understand. It's damaged, it's missing lots of hardware, and this engine isn't made anymore. We are repurposing it by turning it into an educational display, there is really no more functional purpose it can serve. I'd love to get it running again, but it's not within the budget, if even possible :[ |
