About the Book
This book brings together, for the first time, the experience of a group of international authors who have been closely involved in the design of air intakes for both airframe and engine manufacturers. Valuable data from systematic experimental measurements on intakes for missiles, combat and V/STOL aircraft research sources in the UK, USA, France and Germany is included, together with the latest developments in computational fluid dynamics applied to air intakes.
