Low‐Drag and Suction Aerofoils: The Eleventh Wright Brothers Lecture delivered by Dr Sydney Goldstein, Chairman of the Aeronautical Research Council, before the Institute of the Aeronautical Sciences on December 17th, 1947

I SHOULD like first to say how much I appreciate the honour of being invited to deliver the Wright Brothers Lecture. To anyone whose work is associated in any way with the aeronautical sciences, it must be a source of pride and gratification to be invited to be a chief participant in one of the greatest occasions in the world of aeronautical research, an occasion designed in honour of the two great pioneers, Wilbur and Orville Wright. In my own case these feelings are shared with a feeling of humility and of my own unworthiness for the task.
