Turbo/Supercharger Compressors and Turbines for Aircraft Propulsion in WWII (TSCT) is another Great book from Calum Douglas.
I shall say a little more of my impressions to guide interested readers.
Calum has used the original papers of Prof Kollmann to produce a coherent modern translation and analysis of the Second World War Supercharger technology. Written with the assistance of Dr S. Can Gulen, the book is a superb volume for anyone interested in the subject.
Of great merit, the book combines the theoretical and technical detail with a clear and readable text. It can be read and understood by both experts and enthusiasts alike. The text reads easily and the mathematics is there but, it is not necessary to be a mathematician because the words also explain the detail. At the same time, for those of you who are mathematicians or thermodynamicists, you will find that the technical detail is there!
Beyond the theory, this book contains another dimension of the material covered in Calum's previous book, The Secret Horsepower Race, and I would consider them as companion volumes. The book continues from exhaust gas turbines into a chapter on German Turbojets.
So, that is it, a Great book. I do think that TSCT rates as a companion volume to TSHR. However, this book is more expensive. I looked at it this way, TSHR is cheap and if you buy this book, Turbo/Supercharger Compressors and Turbines, as a companion volume you get a set at a good overall price for books that really re-define the technology of WW2 aero engines.
IMO, this book really must be on the bookshelf of any serious WW2 Air Warfare enthusiast. It is that simple. This book will probably not see huge sales, but it is surely the definitive volume that will be published on the subject!
