Part 1, while this is brief, is a comprehensive and detailed summary and covers a significant amount of useful information for both practicing engineers but particularly engineering students. Part II of this book is where it really comes into its own. The book is written in an exceptionally clear manner that will be accessible to all. A sensible mix of theoretical modelling is included where appropriate, but always backed up by clear explanations, diagrams and examples. There are numerous example calculations through the book to help designers get to the fundamentals of the subject in question. As a result the book is of interest to both design and maintenance engineers as well as students. --The Aeronautical Journal
