Pegasus - The Heart of the Harrier: The History and Development of the World's First Operational Vertical Take-off and Landing Jet Engine

The conception of the Pegasus engine in 1957 upset all the conventions of aircraft design. It was previously usual for aircraft designers to seek a suitable engine, but this was an engine that sought an aircraft. The aircraft that resulted was the famous Harrier that is still in front-line service with air forces around the world including the RAF and US Marine Corps. This book takes an in-depth look at the engines original design concept, initial production and flight testing. It then goes on to explain how the developments and improvements have been made over the ensuing years and includes experiences of operational combat flying, both from land and sea. This volume chronicles the making of the Harrier Jump Jet—the innovative Cold War fighter aircraft designed to operate from virtually anywhere. In 1957, the British engine manufacturer Bristol Siddeley turned aircraft design on its head with the creation of the Pegasus engine. Until then, aircraft designs would seek out suitable engines. Now the Pegasus was an engine in search of a suitable aircraft. The result was the famous Hawker Siddeley Harrier, the first military airplane capable of vertical takeoff and landings. To this day, Harrier Jump Jets are still in front-line service with air forces around the world including the Royal Air Force and US Marine Corps. In this volume, former Bristol Siddeley executive Andrew Dow offers an in-depth look at the Pegasus engine's original design concept, production and flight testing. Dow then covers the developments and improvements that have been made over the years. He also includes experiences of operational combat flying, both from land and sea. Written in straightforward prose that avoids technical jargon, Pegasus, The Heart of the Harrier is copiously illustrated with many previously unseen photographs and diagrams.
