It was not until Frank Whittle, a young RAF pilot, persisted with no official support and little money, that a practical jet engine was produced in the late 1930s. Even then, it was not put to use until near the end of World War Two. Today, every country in the world is linked by means of jet propelled aircraft. This book gives the story of how jet and turbine engines have been developed and refined over the years, together with a detailed and accessible description of how they work. This updated edition contains recent developments in jet engine technology including thrust vectoring - as displayed at Paris and Farnborough air shows. It also explains the differences between gas turbines, jet propulsion and rocket motors, and details rocket and ramjet engines, turboprops, propfans and helicopter power plants.
