The Sycamore Seeds: The Early History of the Helicopter
Overview
Britain’s rotorcraft beginnings—from autogyros to the nation’s first production helicopter. Tracing a line from Denny Mumford and Juan de la Cierva to Weir’s W.5/W.6 and the Bristol Sycamore, it uses company files, drawings, and test notes to explain breakthroughs in tail‑fans, tailless rotors, and control systems, as well as setbacks such as the Air Horse.
