Ok, it's the hot core of an engine with fan assembly and internal shroud attached. But beyond that, it doesn't give me any INFORMATION. Perhaps you should submit it to www.aircraftparts.com
But seriously, I think Bronko's suggestion of a Technical Photos category is quite a valid suggestion and bears serious consideration.
The problem I see however in a Technical Photos category is where do you draw the line. If it's the full engine as shown here, well ok, but what happens when I show a photo of a "black box" say like a FADEC box (Full Authority Digital Engine Controls) or say a flap retract proximity switch sensor? Where do we draw the line. When someone sends in a macro shot of a single cold set rivet? Bears thinking about.
