He had only recently, much to the satisfaction of his many friends and associates, returned to aviation, in which he had filled such a distinguished part during the War, and he had only just been elected a member of the Society. His loss will be very keenly felt. [Main Left Clipping] MISS ENGLAND'S ENGINES THE NEW BRITISH ALLOY (FROM OUR MOTORING CORRESPONDENT) The Rolls-Royce engines in Sir Henry Segrave's boat, Miss England II., were constructed largely of the recently discovered aluminium alloy known as Hiduminium R.R. 50. Evolved in the Rolls-Royce laboratories, R.R. 50 was one of the secrets of the engines which won the Schneider Trophy for this country last September. Though originally designed to give 875 h.p. each unit was lightened and modified until it delivered nearly 2,000 b.h.p. with a power-weight ratio of 12oz. per brake-horse power—an astonishing figure for a water-cooled engine, and this with an even greater factor of reliability than before, thanks to the adoption of the new metal. The reason is that R.R. 50 is not only lighter and tougher than former aluminium alloys; it has many times their resistance to fatigue under the stress of heat and prolonged vibration. The engines in Miss England II. are very similar to those of the victorious Schneider seaplanes, which successfully withstood the severe strains of flying for long periods at over 350 m.p.h.; but in the boat an even greater power output, and consequent lower weight per horse power, was obtained from them. Another advantage of R.R. 50 is that it is cheaper to produce than former alloys, and already, it is stated officially, inquiries from Continental countries have been so numerous and valuable that the licensees have found it necessary to open an office in Paris to deal with the growing foreign business in the new metal.
