Anyone know what this is?

:? Hi All:
I am a voulenteer at a small museum
www.indianamilitarymuseum.org
and while poking around in one of our storage areas I ran across this piece. It is about 30" tall and 24" in diameter. I think it may be a Rato unit of some kind or what? Any ideas would be appreciated.

Thanks
Frank

kind of hard to help you when we can't view the photos, it says access forbidden

I have no idea why that would come up. I can see them from my computer. I'll try to find out what's going on, thanks

You have to make the album public. You can see it because it's your album and you're logged into Kodak's servers.

I would suggest that you just open a Photobucket account and upload the pictures there. It's "harder" than using Kodak, but it will automatically resize the image for you and provide you with quick (and automatic) copying of the text needed to imbed your photos within the post so people can just see them when they look at the thread instead of having to click on each link. Just click on the field that says "IMG Code" next to it and it will automatically copy the text in it so all you have to do is click "Paste" in the "Message Body" field on here.

OK let's try this again

Looks like a can-annular burner unit for some type of jet engine. A good deal crushed. Not certain, but that is my guess...

PS- The grey bolt together rim looks like it is from a WC series WWII Dodge truck.

I'm pretty sure about it being an early burner setup- you can see the inlet guide vanes, which look like a fixed fan, in the end of each one, and also you can see there is actually an inner can within the outer can, within the housing: The inner can is most likely perforated, to allow the cooling and combustion air to circulate.

Need a jet engine expert to determine which model... I'd say a Junkers Jumo...The center and end sections are missing, but I'm pretty certain, based on the holes in the housing, and other details I can see...

Look at the bottom picture- ignore the big cutaway sections themselves, but look at the area inside them. Also, look at the interconnections between the cans- they are pretty identical, as are the round access cutouts.

Your museum may be abe to rectify this piece into a nice cutaway of a burner section...

:D Wow! Thanks guys. I think it shure might be for the Junkers Jumo especially since we have a cut away of one. As suggested this might be a good project to make a cut away to match. Any more info is appreciated.

Thanks again

Finally a warbird engine I can recognize. I agree that it appears to be a hot section for a Jumo 004, quite a rare find as only a relative few were shipped to the States for research.

Glad somebody concurs! I just started looking at pics of turbine hot sections, and was pretty well convinced that was what it would be... :)

I don't have lots of experience with turbines, but I think I know 'em when I see one! lol

The cool thing about the German turbine technology to me is the fact that they were able to make the hot section stay together as long as it did with the metallurgical resources they had. Plain old steel and other less-than-desireable alloys had to be used because no better materials were available. The stuff I wrench on every day is made from pure unobtainium by comparison, and we still have cracking and deterioration from time to time. Those BMW and Junkers engineers were light years ahead of the state of the art of the time, not to mention von Ohain (and Whittle in Great Britain) for pioneering the technology used.

Wow, quite a find indeed.

Cheers,
