The honour that has been accorded me in being invited to deliver the Second Halford Lecture is very much appreciated. My personal acquaintance with Major Halford began about fifteen years ago, and every step since has been one of increasing respect and esteem. It is a privilege and pleasure to pay tribute to the memory of a man whom I recall as an effective crusader for simplicity and reliability in engine design. In the First Lecture, John Brodie discussed very fully the contribution of Major Halford to aircraft power plants, and little is left for subsequent lectures on this subject. I have therefore chosen to speak on the propulsion problems of high-speed aircraft—a field of primary interest to Halford, as demonstrated by the outstanding success of the Goblin and Ghost engines, and more recently by the Gyron series designed for supersonic propulsion.
