Today's mystery object

This help any?

Yes, it looks more light-alloy than cast-iron in that shot…

…which was one of the things I had against it being the compressor-casting for a jet-engine.

Maybe not a Heinkel-Hirth HeS 011 but there seem to be startling similarities?

This help any?

Now we have some scale i guess we can eliminate domestic size washing machines at least.

It looks a bit like the exhaust outlets you would get on a rocket engine?
V2 perhaps?

A supercharger casing ? but from what or inside what, hmmm

Could it be part of a Heinkel-Hirth HeS 011 jet-engine?

The turbine-rotor behind it got me thinking about early German jet-engines. From the top are we looking at the air inlet with central shaft and gear power-take-off (through the hollow radial tunnels) to the starter / auxiliaries mounted on the flange / engine mount. The lower portion being the axial compressor with three rows of fixings for the stator blades?

Or it could be a washing-machine…

Is it a single-piece casting? If it is, from an engineering perspective, there would need to be very good reason for it to be made that way. The lattice-work ribs of the lower portion will add great strength without adding much weight or much extra material.

So were a large number of these made to justify the saving in material and the cost of the casting process?

Or was the strength and low weight the issue (whatever the cost)?

Washing machine drume and backplane?

Flowerpot with cupholders?
