Book excerpt: The Fairey Rotodyne was a large British compound helicopter designed and built by the Fairey Aviation Company and intended for commercial and military applications. It was considered to be one of the iconic aviation projects of the 1950s/60s and a bright future was planned for the aircraft. Widely accepted to be a revolutionary design, it was economically viable, fast and capable of vertical take-off and landing from city centre heliports. However, despite the proven feasibility of this bold concept, the Rotodyne project was terminated in 1962 due to escalating development costs and unresolved technical issues. This book seeks to fill a gap in aviation literature on the history of the Rotodyne, an aircraft ahead of its time. Winner of Hampshire Libraries Special Collections Award 2010.
