I am a fan of turbo compound engines and I did
not know Allison was the first to build one let
alone that they built one in the first place.
I am sure learning a lot from this book.

19% better fuel consumption with 19% better
power with no increase in cooling capacity required.
Looks like what they needed was an Inconel turbine wheel.

Curtis Wright solved the problem with the R3350-TC
by using aircooled turbine blades. See the ACRE web
site for a picture of the R3350 turbo compound.

Picture is from a new book by 
Daniel D. Witney. Vee's For Victory. The Story
Of The Allison V-1710 Aircraft Engine 1929-1948.
