B-17 engine evolution
 

Dear Fellows,

I'm busy making a 1/32 model of the B-17 Flying fortress.
Waiting that paint is dry, i'm busy to read about this bomber, something is not clear for me.

from what I read, the B-17 was equipped with engine Wright R-1820 cyclone as summarized here under::
The Y1B17 with R-1820-32
The B-17B with R-1820- (I don't know the version)
The B-17C with R-1820- (I don't know the version)
The B-17D with R-1820- (I don't know the version)
The B-17E with R-1820-65
The B-17,F and G with the R-1820-97

What i'm interested to know is what changes has been introduced between each version of the R-1820-32,-65, -97
As well I saw a engine R-1820 -G2 for the B-17G...is it the R-1820 97 ?

I read as well that certain engines were equipped with a turbocharger from General electric...if fellows can have the patience to tell me more about that...

Thanks in advance

Philippe

The spec sheets at AEHS Home list the following variants:

R-1820-51: YB-17A, B-17B, B-17C, B-17D
R-1820-65: B-17C, B-17D, B-17E, B-17F, B-17G
R-1820-91: B-17E
R-1820-93: B-17H
R-1820-97: B-17F, B-17G, B-17H

Designations such as R-1820-G2 are the manufacturer's series, not the military one. The R-1820-97 was the Wright R-1820-G666A, for example.

Tried to send you a PM, but your inbox is full.

Might be 'cos Phigla is a new member - think some PPRuNe functions only kick in after 10 posts or something...

Lots of info about superchargers here:

The Turbosupercharger and the Airplane Power Plant

That makes sense. If the OP is reading this, I was going to point them to USAF Engine Models

Knowing that the B-17 s/n 42-31585 "Mount N Ride" has been interned by the Swiss Airforce, is it somewhere a tool to know what happened to it in Swiss?

As well, knowing that the B-17 Mount N Ride was part of the production block B-17G-20-BO: 42-31432 to 42-31631 ( info from internet) is it a tool to trace the history of that aircraft 42-31585.

In other words is it a tool to access to the log-book of it and as well to the crew log-book.

Difficult question.

Only info to hand.

42-31585 (323rd BS, 91st BG, *Mount'n Ride*) in emergency landing at Dudendorf, Switzerland after flak hit Mar 16, 1944 and interned. MACR 3221. Returned to UK at end of war and scrapped Oct 8, 1945.

Dear Fellows,

Thanks to you, for the information sent,
I make some slow progress about it.
Because the mailbox limitation to ONE message received or sent i'm a bit limited.
Please, if possible and not to boring, use email
Thanks

Best Regards

Philippe

Best regards

Dear Fellows,

I have another trivial question
For the prototype Model 299 it was 9 crews, for the B-17F and G it was 10 cews
For the Y1B17 I read 6 crews
My question is"
what is the number of crew and function for the Model 299, Y1B17, Y1B19A, B-17-B, B-17C,

Thanks in advance
