Extract

The CHAIRMAN, introducing the author, said Mr HAYWARD IS a member of the Helicopter Association of Great Britain He is a Bristol man, having been educated m that city, and later he served a five-year apprenticeship with the Bristol Aeroplane Company, Limited He served for some time on the technical staff of D Napier & Son, returning to The Bristol Aeroplane Company in 1945, and from there joined the Fairey Aviation Company as Patent Engineer

The title of Mr Hayward's paper is, I think, deceptive, for not only does he give a comprehensive review of the helicopter patent situation, but m addition almost a complete history of the helicopter through the ages, from Leonardo da Vinci to present day developments in the propulsion of helicopter rotors by jet motor
