SPEEDS OF AIRCRAFT

OVER 400 MILES AN HOUR Opinions Of Engineer Military aeroplanes capable of speeds of more than 400 miles an hour are engaging the thoughts of British designers. Mr. A. H. R. Fedden, chief engineer of the Bristol Aeroplane Company’s engine department, quoted between 425 and 450 miles an hour as the maximum speed likely to be attained' within the next five years by one category of aeroplane. His remarks were made in a paper which he read before the Royal Aeronautical Society. Mr. Fedden said aircraft designers were awaiting the resul's of important research work on the shape of aeroplane wings which have have farreaching effects on engine design. Speeds of the order contemplated meant use of a good deal of power, therefore a, considerable step up in the unit size of engines was likely. He forecast that the trend of aircraft design would be in the direction of submerging engines entirely within the covering of the wings
