• Sommario/riassunto: Mechanics of Flight is an ideal introduction to the principles of flight. The eleventh edition has been updated to conform to current teaching practices and technical knowledge. Written in a clear jargon-free style, the book contains simple numerical examples.The book commences with a summary of the relevant aspects of mechanics, and goes on to cover topics such as air and airflow, aerofoils, thrust, level flight, gliding, landing, performance, manoeuvres and stability and control. Important aspects of these topics are illustrated by a description of a trial flight in a light aircraft. The book also deals with flight at transonic and supersonic speeds, and finally orbital flight and spacecraft.
