Hi everyone thanks for adding me to the group.
Wanting to know if the turbo-supercharger used in ww2 aircraft were all the same.
No, they were not.
The US had two basic versions - the B-type (for engines of around 1500hp - like the V-1710 or R-1820) and the C-Type (for engines of 2,000hp and more - the R-2800). These were of teh same basic design, with an axial turbine and centrifugal compressor.
Germany had a turbo, at least on BMW radials (I believe it was a BMW design). I think that the basic layout was the same, though air cooled blades were developed for the turbine during the war.
Japan had some turbos as well, but I don't know anything about them.
So the one on a p-38 is the same as a b-17
Thanks for welcoming me.Yes, and the B-24.
There were also sub-variants, with different altitude ratings.
The CHM type turbosupercharger was a high altitude variant, used in late model P-47s.
Also, welcome to the forum.
Johno - I am very interested in your turbos. I couldn't open the link to the photos. Can you re-post or send them to me off-forum?

You can see the near-side wastegate on the side view, with the outlet louvres. There was one per side.
I notice in different pictures I have found that the cooling cap cn be bolted in several positions.Forgot to add a few links

The BMW engines used Hirth turbochargers.No, they were not.
The US had two basic versions - the B-type (for engines of around 1500hp - like the V-1710 or R-1820) and the C-Type (for engines of 2,000hp and more - the R-2800). These were of teh same basic design, with an axial turbine and centrifugal compressor.

Would the unit pictured have been built by General Electric?The BMW engines used Hirth turbochargers.
